+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.

+   ==================
+3.1 Registers
+    ~~~~~~~~~
+By echoing a hexadecimal value to a register it contents can be altered.
+For example:

+         A: 1 = absolute mode (needs 4 byte packets, see reg_11)

+         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?
