[PATCH 0/2] Add rockchip-timer for RK356X

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add the rockchip-timer to the RK356x SoC. The timer for the RK356x is
register compatible with the rk3288. Address range taken from BSP
device tree and confirmed with rk3568 technical reference manual.

Please make sure to check get_maintainers to catch all needed recipients.

# scripts/get_maintainer.pl -f Documentation/devicetree/bindings/timer/rockchip,rk-timer.yaml

you're especially missing the clocksource maintainers:
    Daniel Lezcano <daniel.lezcano@kernel.org> (maintainer:CLOCKSOURCE, CLOCKEVENT DRIVERS,in file)
    Thomas Gleixner <tglx@kernel.org> (maintainer:CLOCKSOURCE, CLOCKEVENT DRIVERS)

and some additional lists:
    linux-kernel@vger.kernel.org (open list:CLOCKSOURCE, CLOCKEVENT DRIVERS)
    linux-arm-kernel@lists.infradead.org (moderated list:ARM/Rockchip SoC support)

the clocksource part does not seem to have a dedicated list, so
linux-kernel should be included.

I apologize, sorry about that. I assumed since I was only modifying the
device-tree and bindings I didn't need to copy the rest of the teams.

Should I resubmit with the additional names?

Thank you,
Chris

very likely ... i.e. the binding is generally going through the driver-tree
here the tree holding the clocksource drivers.

For me to apply the binding, I'd definitly need an Ack from the clocksource
people.

Resending since I left a few key people off, sorry about that.
