This series of patches enables to boot MSM8226 SoC in Samsung Galaxy S III Neo
mobile phone. Implemented clocks are on top of MSM8974 GCC driver because there
is really little difference between them. UART serial communication is working.
I have working patches for the regulators, EMMC, multithreading and Wifi for
this device but they are not clean and ready to submit.
