+Elantech Touchpad Driver
+========================
+
+ Copyright (C) 2007-2008 Arjan Opmeer <arjan@opmeer.net>
+
+ Extra information for hardware version 1 found and
+ provided by Steve Havelka
+
+ Version 2 (EeePC) hardware support based on patches
+ received from Woody at Xandros and forwarded to me
+ by user StewieGriffin at the eeeuser.com forum
+
+
+Contents
+~~~~~~~~
+
+ 1. Introduction
+ 2. Extra knobs
+ 3. Hardware version 1
+ 3.1 Registers
+ 3.2 Native relative mode 4 byte packet format
+ 3.3 Native absolute mode 4 byte packet format
+ 4. Hardware version 2
+ 4.1 Registers
+ 4.2 Native absolute mode 6 byte packet format
+ 4.2.1 One finger touch
+ 4.2.2 Two finger touch
+
+
+
+1. Introduction
+ ~~~~~~~~~~~~
+
+Currently the Linux Elantech touchpad driver is aware of two different
+hardware versions unimaginatively called version 1 and version 2. Version 1
+is found in "older" laptops and uses 4 bytes per packet. Version 2 seems to
+be introduced with the EeePC and uses 6 bytes per packet.
+
+The driver tries to support both hardware versions and should be compatible
+with the Xorg Synaptics touchpad driver and its graphical configuration
+utilities.
+
+Additionally the operation of the touchpad can be altered by adjusting the
+contents of some of its internal registers. These registers are represented
+by the driver as sysfs entries under /sys/bus/serio/drivers/psmouse/serio?
+that can be read from and written to.
+
+Currently only the registers for hardware version 1 are somewhat understood.
+Hardware version 2 seems to use some of the same registers but it is not
+known whether the bits in the registers represent the same thing or might
+have changed their meaning.
+
+On top of that, some register settings have effect only when the touchpad is
+in relative mode and not in absolute mode. As the Linux Elantech touchpad
+driver always puts the hardware into absolute mode not all information
+mentioned below can be used immediately. But because there is no freely
+available Elantech documentation the information is provided here anyway for
+completeness sake.
+
+
+/////////////////////////////////////////////////////////////////////////////
+
+
+2. Extra knobs
+ ~~~~~~~~~~~
+
+Currently the Linux Elantech touchpad driver provides two extra knobs under
+/sys/bus/serio/drivers/psmouse/serio? for the user.
+
+* debug
+
+ Turn different levels of debugging ON or OFF.
+
+ By echoing "0" to this file all debugging will be turned OFF.
+
+ Currently a value of "1" will turn on some basic debugging and a value of
+ "2" will turn on packet debugging. For hardware version 1 the default is
+ OFF. For version 2 the default is "1".
+
+ Turning packet debugging on will make the driver dump every packet
+ received to the syslog before processing it. Be warned that this can
+ generate quite a lot of data!
+
+* paritycheck
+
+ Turns parity checking ON or OFF.
+
+ By echoing "0" to this file parity checking will be turned OFF. Any
+ non-zero value will turn it ON. For hardware version 1 the default is ON.
+ For version 2 the default it is OFF.
+
+ Hardware version 1 provides basic data integrity verification by
+ calculating a parity bit for the last 3 bytes of each packet. The driver
+ can check these bits and reject any packet that appears corrupted. Using
+ this knob you can bypass that check.
+
+ It is not known yet whether hardware version 2 provides the same parity
+ bits. Hence checking is disabled by default. Currently even turning it on
+ will do nothing.
+
+
+/////////////////////////////////////////////////////////////////////////////
+
+
+3. Hardware version 1
+ ==================
+
+3.1 Registers
+ ~~~~~~~~~
+
+By echoing a hexadecimal value to a register it contents can be altered.
+
+For example:
+
+ echo -n 0x16 > reg_10
+
+* reg_10
+
+ bit 7 6 5 4 3 2 1 0
+ B C T D L A S E
+
+ E: 1 = enable smart edges unconditionally
+ S: 1 = enable smart edges only when dragging
+ A: 1 = absolute mode (needs 4 byte packets, see reg_11)
+ L: 1 = enable drag lock (see reg_22)
+ D: 1 = disable dynamic resolution
+ T: 1 = disable tapping
+ C: 1 = enable corner tap
+ B: 1 = swap left and right button
+
+* reg_11
+
+ bit 7 6 5 4 3 2 1 0
+ 1 0 0 H V 1 F P
+
+ P: 1 = enable parity checking for relative mode
+ F: 1 = enable native 4 byte packet mode
+ V: 1 = enable vertical scroll area
+ H: 1 = enable horizontal scroll area
+
+* reg_20
+
+ single finger width?
+
+* reg_21
+
+ scroll area width (small: 0x40 ... wide: 0xff)
+
+* reg_22
+
+ drag lock time out (short: 0x14 ... long: 0xfe;
+ 0xff = tap again to release)
+
+* reg_23
+
+ tap make timeout?
+
+* reg_24
+
+ tap release timeout?
+
+* reg_25
+
+ smart edge cursor speed (0x02 = slow, 0x03 = medium, 0x04 = fast)
+
+* reg_26
+
+ smart edge activation area width?
+
+
+3.2 Native relative mode 4 byte packet format
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+

+ bit 7 6 5 4 3 2 1 0
+ c c p2 p1 1 M R L

- * DS1286 Real Time Clock interface for Linux
- *
- * Copyright (C) 1998, 1999, 2000 Ralf Baechle
- *
- * Based on code written by Paul Gortmaker.
- *
- * This driver allows use of the real time clock (built into nearly all
- * computers) from user space. It exports the /dev/rtc interface supporting
- * various ioctl() and also the /proc/rtc pseudo-file for status
- * information.
- *
- * The ioctls can be used to set the interrupt behaviour and generation rate
- * from the RTC via IRQ 8. Then the /dev/rtc interface can be used to make
- * use of these timer interrupts, be they interval or alarm based.
- *
- * The /dev/rtc interface will block on reads until an interrupt has been
- * received. If a RTC interrupt has already happened, it will output an
- * unsigned long and then block. The output value contains the interrupt
- * status in the low byte and the number of interrupts since the last read
- * in the remaining high bytes. The /dev/rtc interface can also be used with
- * the select(2) call.
- *
- * This program is free software; you can redistribute it and/or modify it

+ Say Y here if you have an Elantech PS/2 touchpad connected
+ to your system.
+
+ Note that if you enable this driver you will need an updated
+ X.org Synaptics driver that does not require ABS_PRESSURE
+ reports from the touchpad (i.e. post 1.5.0 version). You can
+ grab a patch for the driver here:
+
+ http://userweb.kernel.org/~dtor/synaptics-no-abspressure.patch
+
+ If unsure, say N.
+
+ This driver exposes some configuration registers via sysfs
+ entries. For further information,

- * Device driver for the PCMCIA controller module of the
- * Hitachi HD64465 handheld companion chip.
- *
- * Note that the HD64465 provides a very thin PCMCIA host bridge
- * layer, requiring a lot of the work of supporting cards to be
- * performed by the processor. For example: mapping of card
- * interrupts to processor IRQs is done by IRQ demuxing software;
- * IO and memory mappings are fixed; setting voltages according
- * to card Voltage Select pins etc is done in software.
- *
- * Note also that this driver uses only the simple, fixed,
- * 16MB, 16-bit wide mappings to PCMCIA spaces defined by the
- * HD64465. Larger mappings, smaller mappings, or mappings of
- * different width to the same socket, are all possible only by
- * involving the SH7750's MMU, which is considered unnecessary here.
- * The downside is that it may be possible for some drivers to
- * break because they need or expect 8-bit mappings.
- *
- * This driver currently supports only the following configuration:
- * SH7750 CPU, HD64465, TPS2206 voltage control chip.
