clocksource: vf_pit_timer: Support shutdown mode ... In order to avoid waking up the system in a low power mode, the clocksource should not generate interrupts anymore. Disable the PIT timer interrupt when changing into the CLOCK_EVT_MODE_SHUTDOWN mode.

clocksource: vf_pit_timer: use complement for sched_clock reading ... Vybrids PIT register is monitonic decreasing. However, sched_clock reading needs to be monitonic increasing. Use bitwise not to get the complement of the clock register. This fixes the clock going backward. Also, the clock now starts at 0 since we load the register with the maximum value at start.

clocksource: vf_pit_timer: Switch to sched_clock_register() ... 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.

clocksource: vf_pit_timer: Use linux/sched_clock.h ... Commit 38ff87f7 (sched_clock: Make ARM's sched_clock generic for all architectures) changed the header to <linux/sched_clock.h>, so adapt it in order to fix the following build error: drivers/clocksource/vf_pit_timer.c:15:29: fatal error: asm/sched_clock.h: No such file or directory Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Cc: shawn.guo@linaro.org Cc: sboyd@codeaurora.org Cc: john.stultz@linaro.org Link: http://lkml.kernel.org/r/1372116008-2323-1-git-send-email-festevam@gmail.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Fabio Estevam   authored and   Thomas Gleixner   commited 2013-06-25 01:41:48 +02:00	2699339361
