Merge branch 'akpm' (patches from Andrew)
Merge first patch-bomb from Andrew Morton:
- A few hotfixes which missed 4.4 becasue I was asleep. cc'ed to
-stable
- A few misc fixes
- OCFS2 updates
- Part of MM. Including pretty large changes to page-flags handling
and to thp management which have been buffered up for 2-3 cycles now.
I have a lot of MM material this time.
[ It turns out the THP part wasn't quite ready, so that got dropped from
this series - Linus ]

+* ARM Secure world bindings
+
+ARM CPUs with TrustZone support have two distinct address spaces,
+"Normal" and "Secure". Most devicetree consumers (including the Linux
+kernel) are not TrustZone aware and run entirely in either the Normal
+world or the Secure world. However some devicetree consumers are
+TrustZone aware and need to be able to determine whether devices are
+visible only in the Secure address space, only in the Normal address
+space, or visible in both. (One example of that situation would be a
+virtual machine which boots Secure firmware and wants to tell the
+firmware about the layout of the machine via devicetree.)
+
+The general principle of the naming scheme for Secure world bindings
+is that any property that needs a different value in the Secure world
+can be supported by prefixing the property name with "secure-". So for
+instance "secure-foo" would override "foo". For property names with
+a vendor prefix, the Secure variant of "vendor,foo" would be
+"vendor,secure-foo". If there is no "secure-" property then the Secure
+world value is the same as specified for the Normal world by the
+non-prefixed property. However, only the properties listed below may
+validly have "secure-" versions; this list will be enlarged on a
+case-by-case basis.
+
+Defining the bindings in this way means that a device tree which has
+been annotated to indicate the presence of Secure-only devices can
+still be processed unmodified by existing Non-secure software (and in
+particular by the kernel).
+
+Note that it is still valid for bindings intended for purely Secure
+world consumers (like kernels that run entirely in Secure) to simply
+describe the view of Secure world using the standard bindings. These
+secure- bindings only need to be used where both the Secure and Normal
+world views need to be described in a single device tree.
+
+Valid Secure world properties:
+
+- secure-status : specifies whether the device is present and usable
+ in the secure world. The combination of this with "status" allows
+ the various possible combinations of device visibility to be
+ specified. If "secure-status" is not specified it defaults to the
+ same value as "status"; if "status" is not specified either then
+ both default to "okay". This means the following combinations are
+ possible:
+
+ /* Neither specified: default to visible in both S and NS */
+ secure-status = "okay"; /* visible in both */
+ status = "okay"; /* visible in both */
+ status = "okay"; secure-status = "okay"; /* visible in both */
+ secure-status = "disabled"; /* NS-only */
+ status = "okay"; secure-status = "disabled"; /* NS-only */
+ status = "disabled"; secure-status = "okay"; /* S-only */
+ status = "disabled"; /* disabled in both */
+ status = "disabled"; secure-status = "disabled"; /* disabled in both */

+Binding for Samsung S2M and S5M family clock generator block
+============================================================
+
+This is a part of device tree bindings for S2M and S5M family multi-function
+devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
+outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
+
+To register these as clocks with common clock framework instantiate under
+main device node a sub-node named "clocks".
+
+It uses the common clock binding documented in:
+ - Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+
+Required properties of the "clocks" sub-node:
+ - #clock-cells: should be 1.
+ - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
+ "samsung,s2mps14-clk", "samsung,s5m8767-clk"
+ The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
+ clocks.
+
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.
+ Clock ID Devices
+ ----------------------------------------------------------
+ 32KhzAP 0 S2MPS11/13/14/15, S5M8767
+ 32KhzCP 1 S2MPS11/13/15, S5M8767
+ 32KhzBT 2 S2MPS11/13/14/15, S5M8767
+
+Include dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines
+in device tree sources.
+
+
+Example:
+
+ s2mps11_pmic@66 {
+ compatible = "samsung,s2mps11-pmic";
+ reg = <0x66>;
+
+ s2m_osc: clocks {
+ compatible = "samsung,s2mps11-clk";

-* Samsung S5M8767 Voltage and Current Regulator
-
-The Samsung S5M8767 is a multi-function device which includes voltage and
-current regulators, rtc, charger controller and other sub-blocks. It is
-interfaced to the host controller using a i2c interface. Each sub-block is
-addressed by the host system using different i2c slave address. This document
-describes the bindings for 'pmic' sub-block of s5m8767.
-
-Required properties:
-- compatible: Should be "samsung,s5m8767-pmic".
-- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
-
-- s5m8767,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck2 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck3-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck3 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck4-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck4 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck-ds-gpios: GPIO specifiers for three host gpio's used
- for selecting GPIO DVS lines. It is one-to-one mapped to dvs gpio lines.
-
-[1] If none of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
- property is specified, the 's5m8767,pmic-buck[2/3/4]-dvs-voltage'
- property should specify atleast one voltage level (which would be a
- safe operating voltage).
-
- If either of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
- property is specified, then all the eight voltage values for the
- 's5m8767,pmic-buck[2/3/4]-dvs-voltage' should be specified.
-
-Optional properties:
-- interrupt-parent: Specifies the phandle of the interrupt controller to which
- the interrupts from s5m8767 are delivered to.
-- interrupts: Interrupt specifiers for two interrupt sources.
- - First interrupt specifier is for 'irq1' interrupt.
- - Second interrupt specifier is for 'alert' interrupt.
-- s5m8767,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
-- s5m8767,pmic-buck3-uses-gpio-dvs: 'buck3' can be controlled by gpio dvs.
-- s5m8767,pmic-buck4-uses-gpio-dvs: 'buck4' can be controlled by gpio dvs.
-
-Additional properties required if either of the optional properties are used:
-
-- s5m8767,pmic-buck234-default-dvs-idx: Default voltage setting selected from
- the possible 8 options selectable by the dvs gpios. The value of this
- property should be between 0 and 7. If not specified or if out of range, the
- default value of this property is set to 0.
-
-- s5m8767,pmic-buck-dvs-gpios: GPIO specifiers for three host gpio's used
- for dvs. The format of the gpio specifier depends in the gpio controller.
-
-Regulators: The regulators of s5m8767 that have to be instantiated should be
-included in a sub-node named 'regulators'. Regulator nodes included in this
-sub-node should be of the format as listed below.
-
- regulator_name {
- ldo1_reg: LDO1 {
- regulator-name = "VDD_ALIVE_1.0V";
- regulator-min-microvolt = <1100000>;
- regulator-max-microvolt = <1100000>;
- regulator-always-on;
- regulator-boot-on;
- op_mode = <1>; /* Normal Mode */
- };
- };
-The above regulator entries are defined in regulator bindings documentation
-except these properties:
- - op_mode: describes the different operating modes of the LDO's with
- power mode change in SOC. The different possible values are,
- 0 - always off mode
- 1 - on in normal mode
- 2 - low power mode
- 3 - suspend mode
- - s5m8767,pmic-ext-control-gpios: (optional) GPIO specifier for one
- GPIO controlling this regulator (enable/disable); This is
- valid only for buck9.
-
-The following are the names of the regulators that the s5m8767 pmic block
-supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
-as per the datasheet of s5m8767.
-
- - LDOn
- - valid values for n are 1 to 28
- - Example: LDO1, LDO2, LDO28
- - BUCKn
- - valid values for n are 1 to 9.

+Binding for Samsung S2MPA01 regulator block
+===========================================
+
+This is a part of device tree bindings for S2M family multi-function devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPA01 device provide buck and LDO regulators.
+
+To register these with regulator framework instantiate under main device node

+ - Example: BUCK1, BUCK2, BUCK9
+Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
+as per the datasheet of device.
+
+
+Optional properties of buck regulator nodes under "regulators" sub-node:
+ - 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.

+ will be set for a particular group of bucks so provide the same
+ regulator-ramp-delay value for them.
+ Groups sharing ramp rate:
+ - buck{1,6},
+ - buck{2,4},
+ - buck{8,9,10}.

+
+1) Main node
+
+ Required properties:
+
+ - compatible: must be "cavium,octeon-5750-usbn"
+
+ - reg: specifies the physical base address of the USBN block and
+ the length of the memory mapped region.
+

+
+ - ranges: specifies the translation between child address space and parent
+ address space.
+
+ - clock-frequency: speed of the USB reference clock. Allowed values are
+ 12000000, 24000000 or 48000000.
+
+ - cavium,refclk-type: type of the USB reference clock. Allowed values are

+
+ - refclk-frequency: deprecated, use "clock-frequency".
+
