Merge tag 'timers-v6.11-rc1' of https://git.linaro.org/people/daniel.lezcano/linux into timers/core
Pull clocksource/event driver updates from Daniel Lezcano: - Remove unnecessary local variables initialization as they will be initialized in the code path anyway right after on the ARM arch timer and the ARM global timer (Li kunyu) - Fix a race condition in the interrupt leading to a deadlock on the SH CMT driver. Note that this fix was not tested on the platform using this timer but the fix seems reasonable enough to be picked confidently (Niklas Söderlund) - Increase the rating of the gic-timer and use the configured width clocksource register on the MIPS architecture (Jiaxun Yang) - Add the DT bindings for the TMU on the Renesas platforms (Geert Uytterhoeven) - Add the DT bindings for the SOPHGO SG2002 clint on RiscV (Thomas Bonnefille) - Add the rtl-otto timer driver along with the DT bindings for the Realtek platform (Chris Packham) Link: https://lore.kernel.org/all/91cd05de-4c5d-4242-a381-3b8a4fe6a2a2@linaro.org
