i2c problem with twl4030

Hi,

I am having some problem with i2c.

In my env I cant make i2c working.

During boot, Twl4030 tries to send few i2c data, but it didnt going ok.

static void twl_init_irq(void), issues many i2c write but fails with
error -121 (EREMOTEIO).

I tries to some twl4030 i2c read and write from video driver but also
failes with same error.

My env and my board is based on OMAP2.

with some debugging I found dev->cmd_err is 2.

any idea?

is there any special initialization needed for twl4030?

-SG
