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)
