Pull clocksource updates from Thomas Gleixner:

- Further preparations for modular clocksource/event drivers

- The usual device tree updates to support new chip variants and the
related changes to thise drivers

- Avoid a 64-bit division in the TEGRA186 driver, which caused a build
fail on 32-bit machines.

- Small fixes, improvements and cleanups all over the place

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)

clocksource/drivers/arm_arch_timer: Add standalone MMIO driver

Add a new driver for the MMIO side of the ARM architected timer.
Most of it has been lifted from the existing arch timer code,
massaged, and finally rewritten.

It supports both DT and ACPI as firmware descriptions.
