Pull clock framework changes from Michael Turquette: "The common clk framework changes for 3.12 are dominated by clock driver patches, both new drivers and fixes to existing. A high percentage of these are for Samsung platforms like Exynos.

clocksource: samsung_pwm_timer: Get clock from device tree

2013-09-06T20:33:05Z

When booting with device tree static clkdev aliases should not be used. This patch modifies the samsung_pwm_timer driver to use DT-based clock lookup when booting with device tree. Signed-off-by: Tomasz Figa Signed-off-by: Kyungmin Park Reviewed-by: Sylwester Nawrocki Signed-off-by: Mike Turquette

clocksource: samsung_pwm_timer: Handle suspend/resume correctly

2013-08-05T23:21:43Z

Current suspend/resume handling of the driver was broken, because: - periodic timer was being enabled in CLOCK_EVT_MODE_RESUME mode, which does not seem to be correct behavior looking at other platforms, - PWM divisors need to be restored, but they were not, - clockevent interrupt mask needs to be restored, but it was not, - clocksource was being restored in clockevent resume callback. This patch fixes issues mentioned above, making suspend/resume handling in the driver correct.

clocksource: samsung_pwm_timer: Do not use clocksource_mmio

2013-08-05T23:21:43Z

In case of Samsung PWM timer, clocksource MMIO can not be used, because custom suspend/resume callbacks are required.

clocksource: samsung_pwm_timer: Cache clocksource register address

2013-08-05T23:21:42Z

Instead of calculating register every time the timer should be read, we can just do it one time at initialization and store the address in driver data.

clocksource: samsung_pwm_timer: Correct definition of AUTORELOAD bit

2013-08-05T23:21:41Z

PWM channel 4 has its autoreload bit located at different position. This patch fixes the driver to account for that. This fixes a problem with the clocksource hanging after it overflows because it is not reloaded any more.

clocksource: samsung_pwm_timer: Do not request PWM mem region

The 32 bit sched_clock interface now supports 64 bits. Upgrade to the 64 bit function to allow us to remove the 32 bit registration interface. Cc: Tomasz Figa Cc: Kyungmin Park Cc: Kukjin Kim Signed-off-by: Stephen Boyd Signed-off-by: John Stultz
