Merge tag 'timers-v5.20-rc1' of https://git.linaro.org/people/daniel.lezcano/linux into timers/core
Pull clockevent/source updates from Daniel Lezcano: - Add the missing DT bindings for the MTU nomadik timer (Linus Walleij) - Fix grammar typo in the ARM global timer Kconfig option (Randy Dunlap) - Add the tegra186 timer and use it on the tegra234 board (Thierry Reding) - Add the 'CPUXGPT' CPU timer for Mediatek MT6795 and implement a workaround to overcome an ATF bug where the timer is not correctly initialized (AngeloGioacchino Del Regno) - Rework the suspend/resume approach to enable the feature on the timer even it is not an active clock and fix a compilation warning (Claudiu Beznea) - Add the Add R-Car Gen4 timer support along with the DT bindings (Wolfram Sang) - Add compatible for ti,am654-timer to support AM6 SoC (Tony Lindgren) - Fix Kconfig option to put it back to 'bool' instead of 'tristate' for the tegra186 (Daniel Lezcano) - Sort 'family,type' DT bindings for the Renesas timers (Geert Uytterhoeven) - Add compatible 'allwinner,sun20i-d1-timer' for Allwinner D1 (Samuel Holland) - Remove unnecessary (void*) conversions for sun4i (XU pengfei) - Remove unnecessary (void*) conversions for sun5i (Li zeming) Link: https://lore.kernel.org/all/7472984e-f502-5f27-82bf-070127dd85a5@linaro.org
