OMAP UART IP needs manual idle modes based on functional state of the IP. Currently this is handled by the driver with function pointers implemented in platform code. This however breaks in case of device tree because of missing idle handling. The series tries to address the issue and tries to remove complete sysc handling from serial driver. Patches has been tested on OMAP4430 SDP and OMAP5 EVM where the console sluggishness was observed without idle mode handling. CPUIDLE and suspend tested ok on these devices. Thanks to Vaibhav Bedia for testing on Beaglebone(AM33XX) with suspend and also the UART async wakeup from suspend. Thanks to Sourav Poddar for Beagle XM(OMAP3630) devices testing with retention and offmode in Idle and suspend for non-DT builds. Serial driver platform code still has one more function pointer left which is used to trigger io_ring(). This one needs some discussion with pincontrol driver folks on how to implement such a feature with generic pincontrol driver.
