trouble configuring the touchscreen driver for OMAP OSK 5912

[abhishek@nextbitcpu.com]

Hello,

I have been trying to build the linux kernel for the omap osk 5912 with
touchscreen option but it is not working. The OSK is connected to a
Mistral QVLM display module.
 I am using linux kernel version 2.6.18 along with the appropriate omap
patch patch-2.6.18-omap1. After applying the patch i use the following
procedure.

make clean
make omap_osk_5912_defconfig
make menuconfig

I use the following link for reference
http://oskfordummies.hp.infoseek.co.jp/howto/touch.html

According to this refence document i have to enable the  options

CONFIG_INPUT_EVDEV
CONFIG_INPUT_TOUCHSCREEN
CONFIG_TOUCHSCREEN_OMAP

i am not getting any option for CONFIG_TOUCHSCREEN_OMAP. Also while trying
to enable the LCD i dont get an option for CONFIG_FB_OMAP_INTERNAL_LCDC.

here is the Input Device Drivers section of .config file generated after
the 'make menuconfig' command.

#

The graphics support section of .config

# CONFIG_FB_OMAP_BOOTLOADER_INIT is not set

# CONFIG_FB_OMAP_DMA_TUNE is not set

Still i continued with the following procedure and loaded the kernel using
using tftp.

$ make
$ arm-linux-objcopy -O binary -R .note -R .comment -S
arch/arm/boot/compressed/vmlinux linux.bin
$ gzip -9 linux.bin
$ /usr/src/u-boot-1.1.6/tools/mkimage -A arm -O linux -T kernel -C gzip -a
0x10c08000 -e 0x10c08000 -n 'Linux Kernel Image' -d linux.bin.gz uImage.cc
$ cp uImage.cc /tftpboot/uImage.cc

The kernel boots correctly but when i run the command

cat /proc/bus/input/devices

nothing is displayed.

Is there anything i missed out when compiling the kernel? Plese help.
