Touchscreen & PMIC

Other Parts Discussed in Thread: OMAP-L138, TPS65070

Hi,

I'm running kernel v2.6.34 from linux/kernel/git/khilman/linux-davinci.git/ on custom hardware based on OMAP-L138 EVM. I got tps65070 to manage power, touchscreen and LCD backlight. My touchscreen is working fine but when I try to communicate with my PMIC by I2C, I got this error  "errno 16 Device or resource busy".

If I disable the touchscreen driver, everything is fine and I can modify PMIC registers without problem.

Any ideas?

Thanks.
Regards,
Nicolas
