[PATCH] i2c-omap: Program I2C_WE on OMAP4 to enable i2c wakeup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For the I2C module to be wakeup capable, programming I2C_WE
register (which was skipped for OMAP4430) is needed
even on OMAP4.
This fixes i2c controller timeouts which were seen recently
with the static dependency being cleared between MPU and
L4PER clockdomains.
