Merge tag 'timers-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource

Pull clocksource/events driver updates from Daniel Lezcano:

   - Add the module owner to all the drivers which can be converted into
     modules in order to have the core time framework to take the
     refcount and prevent wild module removal. In addition export the
     symbols for the sched_clock_register() function to allow the drivers
     to be converted into modules (Daniel Lezcano)

   - Convert the faraday,fttmr010 DT bindings to yaml schema (Rob
     Herring)

   - Add the DT bindings compatible string for the MT6572 (Max
     Shevchenko)

   - Fix the fsl,ftm-timer bindings by using the items to describe a
     register (Frank Li)

   - Add the DT binding documentation for Andes machine timer (Ben
     Zong-You Xie)

   - Avoid 64-bit divide operation which fails on xtensa and simplify the
     timeleft computation with 32 bits operations on Tegra186 (Guenter
     Roeck)

   - Add the fsl,timrot.yaml DT bindings for i.MX23/i.MX28 timer (Frank
     Li)

   - Replace comma by semicolon which were introduced when moving the
     static structure initialization (Chen Ni)

   - Add a new compatible for the MediaTek MT8196 SoC, fully compatible
     with MT6765 (AngeloGioacchino Del Regno)

   - Add the support for the s32g2 and s32g3 platforms in the PIT timer
     after cleaning up the code to support multiple instances (Daniel
     Lezcano)

   - Generate platform devices for MMIO timers with ACPI and integrate it
     with the arch ARM timer (Marc Zyngier)

   - Fix RTL OTTO timer by working around dying timers (Markus Stockhausen)

   - Remove extra error message in the tegra186 timer (Wolfram Sang)

   - Convert from round_rate() to determine_rate() in the Ingenic sysost
     driver (Brian Masney)

   - Add PWM capture functionality in the OMAP DM driver (Gokul Praveen)

   - Autodetect the clock rate to initialize a prescaler value compatible
     with the frequency changes on the ARM global timer (Markus
     Schneider-Pargmann)

   - Fix rollbacks missing resource deallocation in case of error on the
     clps711x (Zhen Ni)

   - Reorganize the code to split the start and the stop routine on the
     sh_cmt driver (Niklas Söderlund)

   - Add the compatible definition for ARTPEC-9 on exynos MCT (SungMin Park)
