+Description:
+ The /sys/devices/.../power/pm_qos_latency_tolerance_us attribute
+ contains the PM QoS active state latency tolerance limit for the
+ given device in microseconds. That is the maximum memory access
+ latency the device can suffer without any visible adverse
+ effects on user space functionality. If that value is the
+ string "any", the latency does not matter to user space at all,
+ but hardware should not be allowed to set the latency tolerance
+ for the device automatically.
+
+ Reading "auto" from this file means that the maximum memory
+ access latency for the device may be determined automatically
+ by the hardware as needed. Writing "auto" to it allows the
+ hardware to be switched to this mode if there are no other
+ latency tolerance requirements from the kernel side.

+Updating on-disk metadata
+-------------------------
+
+On-disk metadata is committed every time a FLUSH or FUA bio is written.
+If no such requests are made then commits will occur every second. This
+means the thin-provisioning target behaves like a physical disk that has
+a volatile write cache. If power is lost you may lose some recent
+writes. The metadata should always be consistent in spite of any crash.
+
+If data space is exhausted the pool will either error or queue IO
+according to the configuration (see: error_if_no_space). If metadata
+space is exhausted or a metadata operation fails: the pool will error IO
+until the pool is taken offline and repair is performed to 1) fix any
+potential inconsistencies and 2) clear the flag that imposes repair.
+Once the pool's metadata device is repaired it may be resized, which
+will allow the pool to return to normal operation. Note that if a pool
+is flagged as needing repair, the pool's data and metadata devices
+cannot be resized until repair is performed. It should also be noted
+that when the pool's metadata space is exhausted the current metadata
+transaction is aborted. Given that the pool will cache IO whose
+completion may have already been acknowledged to upper IO layers
+(e.g. filesystem) it is strongly suggested that consistency checks
+(e.g. fsck) be performed on those layers when repair of the pool is
+required.

+* Samsung S2MPA01 Voltage and Current Regulator
+
+The Samsung S2MPA01 is a multi-function device which includes high
+efficiency buck converters including Dual-Phase buck converter, various LDOs,
+and an RTC. It is interfaced to the host controller using an I2C interface.
+Each sub-block is addressed by the host system using different I2C slave
+addresses.
+
+Required properties:
+- compatible: Should be "samsung,s2mpa01-pmic".
+- reg: Specifies the I2C slave address of the PMIC block. It should be 0x66.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+ the interrupts from s2mpa01 are delivered to.
+- interrupts: An interrupt specifier for the sole interrupt generated by the
+ device.
+
+Optional nodes:
+- regulators: The regulators of s2mpa01 that have to be instantiated should be
+ included in a sub-node named 'regulators'. Regulator nodes and constraints
+ included in this sub-node use the standard regulator bindings which are
+ documented elsewhere.
+
+Properties for BUCK regulator nodes:
+- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
+ (default), 25000, or 50000. May be 0 for disabling the ramp delay on
+ BUCK{1,2,3,4}.
+
+ In the absence of the regulator-ramp-delay property, the default ramp
+ delay will be used.
+
+ NOTE: Some BUCKs share the ramp rate setting i.e. same ramp value will be set
+ for a particular group of BUCKs. So provide same regulator-ramp-delay=<value>.
+
+ The following BUCKs share ramp settings:
+ * 1 and 6
+ * 2 and 4
+ * 8, 9, and 10
+
+The following are the names of the regulators that the s2mpa01 PMIC block

ST pinctrl driver controls PIO multiplexing block and also interacts with

-Required properties: (PIO multiplexing block)
+GPIO bank can have one of the two possible types of interrupt-wirings.
+
+First type is via irqmux, single interrupt is used by multiple gpio banks. This

+a single pincontroller.
+ _________

+Required properties:
- compatible : should be "st,<SOC>-<pio-block>-pinctrl"
like st,stih415-sbc-pinctrl, st,stih415-front-pinctrl and so on.
-- gpio-controller : Indicates this device is a GPIO controller
-- #gpio-cells : Should be one. The first cell is the pin number.
+- st,syscfg : Should be a phandle of the syscfg node.
- st,retime-pin-mask : Should be mask to specify which pins can be retimed.
If the property is not present, it is assumed that all the pins in the
bank are capable of retiming. Retiming is mainly used to improve the
IO timing margins of external synchronous interfaces.
-- st,bank-name : Should be a name string for this bank as
- specified in datasheet.
-- st,syscfg : Should be a phandle of the syscfg node.
+- ranges : defines mapping between pin controller node (parent) to gpio-bank
+ node (children).

+Optional properties:
+- interrupts : Interrupt number of the irqmux. If the interrupt is shared
+ with other gpio banks via irqmux.

+
+Description
+-----------
+
+This driver implements support for the Texas Instruments ADC128D818.
+It is described as 'ADC System Monitor with Temperature Sensor'.
+
+The ADC128D818 implements one temperature sensor and seven voltage sensors.
+
+Temperatures are measured in degrees Celsius. There is one set of limits.
+When the HOT Temperature Limit is crossed, this will cause an alarm that will
+be reasserted until the temperature drops below the HOT Hysteresis.
+Measurements are guaranteed between -55 and +125 degrees. The temperature
+measurement has a resolution of 0.5 degrees; the limits have a resolution
+of 1 degree.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 2.55 volts, with a resolution
+of 0.625 mV.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared by the time the alarm is read. The driver
+caches the alarm status for each sensor until it is at least reported
+once, to ensure that alarms are reported to user space.
+
+The ADC128D818 only updates its values approximately once per second;
+reading it more often will do no harm, but will return 'old' values.
+
+In addition to the scanned address list, the chip can also be configured for
+addresses 0x35 to 0x37. Those addresses are not scanned. You have to instantiate
+the driver explicitly if the chip is configured for any of those addresses in
+your system.

+Each sensor has its own critical limit. Additionally, there is a relative

+Description
+-----------
+
+The LTC2945 is a rail-to-rail system monitor that measures current, voltage,
+and power consumption.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC2945 devices, since there is no register
+which can be safely used to identify the chip. You will have to instantiate
+the devices explicitly.
+
+Example: the following will load the driver for an LTC2945 at address 0x10
+on I2C bus #1:

+real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the
+value of the divider resistor against the measured voltage and R2 is the value
+of the divider resistor against Ground.
+
+Current reading provided by this driver is reported as obtained from the ADC
+Current Sense register. The reported value assumes that a 1 mOhm sense resistor
+is installed. If a different sense resistor is installed, calculate the real
+current by dividing the reported value by the sense resistor value in mOhm.

+ Why does this work?
+
+ One key point is that we are only talking about the CPU doing

+ that matter, the developer) switched the operations, deadlock
+ -could- occur.
+
+ But suppose the CPU reordered the operations. In this case,

+ simply elected to try executing the later lock operation first.
+ If there is a deadlock, this lock operation will simply spin (or
+ try to sleep, but more on that later). The CPU will eventually
+ execute the unlock operation (which preceded the lock operation
+ in the assembly code), which will unravel the potential deadlock,
+ allowing the lock operation to succeed.
+
+ But what if the lock is a sleeplock? In that case, the code will
+ try to enter the scheduler, where it will eventually encounter
+ a memory barrier, which will force the earlier unlock operation
+ to complete, again unraveling the deadlock. There might be
+ a sleep-unlock race, but the locking primitive needs to resolve
+ such races properly in any case.

+Active state latency tolerance
+This device PM QoS type is used to support systems in which hardware may switch
+to energy-saving operation modes on the fly. In those systems, if the operation
+mode chosen by the hardware attempts to save energy in an overly aggressive way,
+it may cause excess latencies to be visible to software, causing it to miss
+certain protocol requirements or target frame or sample rates etc.
+
+If there is a latency tolerance control mechanism for a given device available
+to software, the .set_latency_tolerance callback in that device's dev_pm_info
+structure should be populated. The routine pointed to by it is should implement
+whatever is necessary to transfer the effective requirement value to the
+hardware.
+
+Whenever the effective latency tolerance changes for the device, its
+.set_latency_tolerance() callback will be executed and the effective value will
+be passed to it. If that value is negative, which means that the list of
+latency tolerance requirements for the device is empty, the callback is expected
+to switch the underlying hardware latency tolerance control mechanism to an
+autonomous mode if available. If that value is PM_QOS_LATENCY_ANY, in turn, and
+the hardware supports a special "no requirement" setting, the callback is
+expected to use it. That allows software to prevent the hardware from
+automatically updating the device's latency tolerance in response to its power
+state changes (e.g. during transitions from D3cold to D0), which generally may
+be done in the autonomous latency tolerance control mode.
+
+If .set_latency_tolerance() is present for the device, sysfs attribute
+pm_qos_latency_tolerance_us will be present in the devivce's power directory.
+Then, user space can use that attribute to specify its latency tolerance
+requirement for the device, if any. Writing "any" to it means "no requirement,
+but do not let the hardware control latency tolerance" and writing "auto" to it
+allows the hardware to be switched to the autonomous mode if there are no other
+requirements from the kernel side in the device's list.
+
+Kernel code can use the functions described above along with the
+DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type to add, remove and update
+latency tolerance requirements for devices.

+ * ACPICA policy for new _OSI strings:
+ *
+ * It is the stated policy of ACPICA that new _OSI strings will be integrated
+ * into this module as soon as possible after they are defined. It is strongly
+ * recommended that all ACPICA hosts mirror this policy and integrate any
+ * changes to this module as soon as possible. There are several historical
+ * reasons behind this policy:
+ *
+ * 1) New BIOSs tend to test only the case where the host responds TRUE to
+ * the latest version of Windows, which would respond to the latest/newest
+ * _OSI string. Not responding TRUE to the latest version of Windows will
+ * risk executing untested code paths throughout the DSDT and SSDTs.
+ *
+ * 2) If a new _OSI string is recognized only after a significant delay, this
+ * has the potential to cause problems on existing working machines because
+ * of the possibility that a new and different path through the ASL code
+ * will be executed.
+ *
+ * 3) New _OSI strings are tending to come out about once per year. A delay
+ * in recognizing a new string for a significant amount of time risks the
+ * release of another string which only compounds the initial problem.
+ *

+ * @deadline: deadline jiffies for the operation
+ * @online: Return value to indicate if device online
+ *
+ * Due to the limitation of the hardware PHY, a difference set of setting is
+ * required for each supported disk speed - Gen3 (6.0Gbps), Gen2 (3.0Gbps),
+ * and Gen1 (1.5Gbps). Otherwise during long IO stress test, the PHY will
+ * report disparity error and etc. In addition, during COMRESET, there can
+ * be error reported in the register PORT_SCR_ERR. For SERR_DISPARITY and
+ * SERR_10B_8B_ERR, the PHY receiver line must be reseted. The following
+ * algorithm is followed to proper configure the hardware PHY during COMRESET:
+ *
+ * Alg Part 1:
+ * 1. Start the PHY at Gen3 speed (default setting)
+ * 2. Issue the COMRESET
+ * 3. If no link, go to Alg Part 3
+ * 4. If link up, determine if the negotiated speed matches the PHY
+ * configured speed
+ * 5. If they matched, go to Alg Part 2
+ * 6. If they do not matched and first time, configure the PHY for the linked
+ * up disk speed and repeat step 2
+ * 7. Go to Alg Part 2
+ *
+ * Alg Part 2:
+ * 1. On link up, if there are any SERR_DISPARITY and SERR_10B_8B_ERR error
+ * reported in the register PORT_SCR_ERR, then reset the PHY receiver line
+ * 2. Go to Alg Part 3
+ *
+ * Alg Part 3:
+ * 1. Clear any pending from register PORT_SCR_ERR.
+ *
+ * NOTE: For the initial version, we will NOT support Gen1/Gen2. In addition
+ * and until the underlying PHY supports an method to reset the receiver
+ * line, on detection of SERR_DISPARITY or SERR_10B_8B_ERR errors,
+ * an warning message will be printed.

help
- This driver uses ACPI INT3403 device objects. If present, it will
- register each INT3403 thermal sensor as a thermal zone.
+ Newer laptops and tablets that use ACPI may have thermal sensors
+ outside the core CPU/SOC for thermal safety reasons. These
+ temperature sensors are also exposed for the OS to use via the so
+ called INT3403 ACPI object. This driver will, on devices that have
+ such sensors, expose the temperature information from these sensors
+ to userspace via the normal thermal framework. This means that a wide
+ range of applications and GUI widgets can show this information to
+ the user or use this information for making decisions. For example,
+ the Intel Thermal Daemon can use this information to allow the user
+ to select his laptop to run without turning on the fans.

+ * When retransmitting timed-out data, the endpoint should
+ * attempt to pick the most divergent source-destination

+ *
+ * Note: Rules for picking the most divergent source-destination
+ * pair are an implementation decision and are not specified

'NAME' specifies the name of this argument (optional). You can use the name of local variable, local data structure member (e.g. var->field, var.field2), local array with fixed index (e.g. array[1], var->array[0], var->pointer[2]), or kprobe-tracer argument format (e.g. $retval, %ax, etc). Note that the name of this argument will be set as the last member name if you specify a local data structure member (e.g. field2 for 'var->field1.field2'.)
'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo. You can specify 'string' type only for the local variable or structure member which is an array of or a pointer to 'char' or 'unsigned char' type.
+On x86 systems %REG is always the short form of the register: for example %AX. %RAX or %EAX is not valid.
