This patch introduces new Samsung PWM driver, which is completely rewritten to be multiplatform- and DeviceTree-aware. In addition, remaining problems of old driver are fixed, such as: - proper handling of hardware variants, - synchronization on SMP systems, - handling of boundary parameter values, - hardware sharing with PWM clocksource driver, - undefined state of PWM output after stopping PWM channel.
