clocksource/drivers/exynos_mct: Increase priority over ARM arch timer

2019-07-26T07:12:43Z

[ Upstream commit 6282edb72bed5324352522d732080d4c1b9dfed6 ] Exynos SoCs based on CA7/CA15 have 2 timer interfaces: custom Exynos MCT (Multi Core Timer) and standard ARM Architected Timers. There are use cases, where both timer interfaces are used simultanously. One of such examples is using Exynos MCT for the main system timer and ARM Architected Timers for the KVM and virtualized guests (KVM requires arch timers). Exynos Multi-Core Timer driver (exynos_mct) must be however started before ARM Architected Timers (arch_timer), because they both share some common hardware blocks (global system counter) and turning on MCT is needed to get ARM Architected Timer working properly. To ensure selecting Exynos MCT as the main system timer, increase MCT timer rating. To ensure proper starting order of both timers during suspend/resume cycle, increase MCT hotplug priority over ARM Archictected Timers.

clocksource/drivers/tegra: Restore base address before cleanup

2019-07-26T07:12:43Z

[ Upstream commit fc9babc2574691d3bbf0428f007b22261fed55c6 ] We're adjusting the timer's base for each per-CPU timer to point to the actual start of the timer since device-tree defines a compound registers range that includes all of the timers. In this case the original base need to be restore before calling iounmap to unmap the proper address.

clocksource/drivers/timer-ti-dm: Remove omap_dm_timer_set_load_start

2019-04-16T12:26:54Z

Commit 008258d995a6 ("clocksource/drivers/timer-ti-dm: Make omap_dm_timer_set_load_start() static") made omap_dm_time_set_load_start static because its prototype was not defined in a header. Unfortunately, this causes a build warning on multi_v7_defconfig because this function is not used anywhere in this translation unit: drivers/clocksource/timer-ti-dm.c:589:12: error: unused function 'omap_dm_timer_set_load_start' [-Werror,-Wunused-function] In fact, omap_dm_timer_set_load_start hasn't been used anywhere since commit f190be7f39a5 ("staging: tidspbridge: remove driver") and the prototype was removed in commit 592ea6bd1fad ("clocksource: timer-ti-dm: Make unexported functions static"), which is probably where this should have happened.
