Hello,
i try to get running the tps6507x-ts touchscreen driver on the Kevin Hilman
Davinci kernel tree
(git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-davinci.git).
I enabled the following parts in the kernelconfig:
Device Drivers - Multifunction Device Drivers - TPS6507x Power Management /
Touch Screen chips
Device Drivers - Input device support - Event Interface
Device Drivers - Input device support - Touchscreens - TPS6507x based
touchscreens
That gives a compile error : "can`t find" kzalloc and kfree!
After applying following patch the driver compiles.
diff --git a/drivers/mfd/tps6507x.c b/drivers/mfd/tps6507x.c
index dcddef0..dbaab1a 100644

#include <linux/mfd/tps6507x.h>

On runtime the kernel gives the following error:
tps6507x-ts: probe of tps6507x-ts failed with error -121
Any idea whats to do now?
Thank you very much,

Bastian.
P.S.
