Actally, a better fix for this problem is to completely remove SYSC
register accesses for OMAP3+ platforms. This is handled already at the
hwmod layer.
Also, please Cc linux-omap for OMAP changes.
Agree,
1. Currently the flag HWMOD_INIT_NO_RESET is there for OMAP4.
2. Currently the reset is there even in the error paths and hwmod
takes care of it in init only.
3. I2C reset sequence is disable -> reset -> enable and poll. So it
needs a .reset function in hwmod.
Another issue I am not able to solve currently is that after reset the
restore of settings.
Doing get_sync and put_sync is one option however it will be a hack again.
Anyways fixing it is in my plans till then thought of having it
corrected.
Kevin
