16.1 Patch touch screen driver

In linux 2.6.25.8, there is no touch screen driver for S3C2440. So we need to patch the driver first. First, copy the driver source code we provided

£¨name£ºEmbedSky_ts.c£©to kernel directory “drivers/input/touchscreen/”, and copy header file£¨name£ºts.h£©to kernel directory “include/asm-arm/arch-s3c2410/”. Add “clock.h” to kernel directory “include/asm-arm/hardware/”.

Modify “Kconfig”and“Makefile”under “drivers/input/touchscreen/”to support the newly added files.

Modify file “Kconfig” under “drivers/input/touchscreen/”:

config TOUCHSCREEN_USB_GOTOP

default y

bool “GoTop Super_Q2/GogoPen/PenPower tablet device support” if EMBEDDED

depends on TOUCHSCREEN_USB_COMPOSITE

config EmbedSky_TOUCHSCREEN

tristate “EmbedSky touchscreen”

depends on ARCH_S3C2410 && INPUT && INPUT_TOUCHSCREEN

select SERIO

help

To compile this driver as a module, choose M here: the

module will be called EmbedSky_ts.ko.
