2018-05-06thermal: exynos: check return values of ->get_trip_[temp, hyst] methodsBartlomiej Zolnierkiewicz

2018-05-06thermal: exynos: move trips setting to exynos_tmu_initialize()Bartlomiej Zolnierkiewicz
* Add dummy exynos4210_tmu_set_trip_hyst() helper. * Add ->tmu_set_trip_temp and ->tmu_set_trip_hyst methods to struct exynos_tmu_data and set them in exynos_map_dt_data(). * Move trips setting to exynos_tmu_initialize().

Set trips in ascending order in exynos7_tmu_initialize() (it should make no difference in driver operation).

Since the commit "8003c9ae204e: add APIC Timer periodic/oneshot mode VMX preemption timer support", a Windows 10 guest has some erratic timer spikes. Here the results on a 150000 times 1ms timer without any load: Before 8003c9ae204e | After 8003c9ae204e Max 1834us | 86000us Mean 1100us | 1021us Deviation 59us | 149us Here the results on a 150000 times 1ms timer with a cpu-z stress test: Before 8003c9ae204e | After 8003c9ae204e Max 32000us | 140000us Mean 1006us | 1997us Deviation 140us | 11095us The root cause of the problem is starting hrtimer with an expiry time already in the past can take more than 20 milliseconds to trigger the timer function. It can be solved by forward such past timers immediately, rather than submitting them to hrtimer_start(). In case the timer is periodic, update the target expiration and call hrtimer_start with it. v2: Check if the tsc deadline is already expired. Thank you Mika. v3: Execute the past timers immediately rather than submitting them to hrtimer_start(). v4: Rearm the periodic timer with advance_periodic_target_expiration() a simpler version of set_target_expiration().
