Abhilash ,
I am not sure what is PSP 04.02.00.07 release. But you should make sure
that the hwmod structures in omap_hwmod_3xxx_data.c should have the
16_bit flags.
Below is just a snippet in P.S.. There is already a patch submitted by
andy green for this. Not sure, if it is merged.
With this and the posted v3 patch, you should not see timeouts. Or else
you have some other problem.
thanks ,

PS:
static struct omap_hwmod omap3xxx_i2c1_hwmod = {
.name = "i2c1",
+ .flags = HWMOD_16BIT_REG,
