Add pending general purpose timer support for various J7 family
Full list of K3 SoCs:
* AM625: already merged
* AM62A7: https://lore.kernel.org/all/[email protected]/
* AM64: https://lore.kernel.org/all/[email protected]/
* AM65: already merged
* J7200: https://lore.kernel.org/all/[email protected]/ (needs a respin)
And the timers for remaining J7 platforms (J721e, J721s2, J784s4) are
addressed in this series.

There are 20 general purpose timers on j721s2 that can be used for
things like PWM using pwm-omap-dmtimer driver. There are also
additional ten timers in the MCU domain which are meant for MCU
firmware usage and hence marked reserved by default.
Though the count is similar to J721e/J7200, the device IDs and clocks
used in j721s2 are different with the option of certain clocks having
options of additional clock muxes. Since there is very minimal reuse,
it is cleaner to integrate as part of SoC files itself. The defaults
are configured for clocking the timers from system clock(HFOSC0).

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
