[GIT PULL] clockevents for 4.5

From: Daniel Lezcano
Date: Thu Dec 17 2015 - 09:50:12 EST

Hi Thomas,

this pull request is bigger than the other ones. It contains a lot of changes and cleanups in order to increase the compilation test coverage.

- Add cosmetic changes on error and a memory leakage on failure at init time for the mediatek timer (Alexey Klimov)

- Remove the useless dsb() usage in the rockchip timer, the side effect is it can compile for the ARM and ARM64 (Caesar Wang)

- Huge cleanups and fixes for the timers st_lpc, pxa_timer, tango, pistachio, mediatek, rockchip, armada-370-xp, meson6, orion, digicolor, dw_apb, sun4i, sun5i, tegra2, vt8500, cadence_ttc, asm9260, lpc32xx, nomadik_mtu, prcmu, exynos_mct, samsung-pwm and fsl-ftm in order to add the COMPILE_TEST option (Daniel Lezcano)

- Cleanup of the h8300 timers and add the COMPILE_TEST option (Daniel Lezcano)

- Factor out the tango-xtal and the timer_sun5i code by using the clocksource_mmio_init (Daniel Lezcano)

- Fix suspend / resume on the arch_arm_timer (Grygorii Strashko)

- Implement an ARM delay timer, fix return value and use relaxed io to improve performances on the dw_apb_timer (Jisheng Zhang)

- Improve greatly performances by using writel_relaxed in gt_compare_set in the arm_global_timer (Jisheng Zhang)

- Use the dynamic irq affinity flag on the tegra2 timer (Lucas Stach)

- Correct pr_err() output format on the lpc32 timer (Vladimir Zapolskiy)

- Second round of cleanups on the h8300 timers (Yoshinori Sato)
