[GIT PULL] clockevents for 4.5

[Daniel Lezcano <daniel.lezcano@linaro.org>]

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)
