[PATCH] i2c: nomadik: move runtime suspend of hw to _noirq

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

 



The runtime suspend of the hardware (declocking and pin control
resting) needs to happen in the *_noirq callbacks after all
hardware interrupts are disabled and we know there will be no
more I2C traffic in the system.
