[GIT PULL] amlogic ARM64 DT updates for v6.15

[GIT PULL] amlogic ARM64 DT updates for v6.15

[Neil Armstrong]

Hi,

Here's a changeset for Amlogic ARM64 DT, also switching to the new PWM bindings,
adding pinctrl support for Amlogic A4 SoC with a brand new binding style then
finally gpio_intc node for Amlogic A4 & A5 SoCs.

Thanks,
Neil

I'll skip this one for 6.15, seeing that the branch contains both
driver and devicetree changes, which messes up the way I send
the contents.

From the description I also can't tell to what degree there is
backwards compatibility in the new binding, I assume the changed
PWM and pinctrl drivers continue to work find with the old dts
but not the other way round, which is why you sent them together?

There's an immutable branch in the linux-pinctrl tree from Linus.
I'm not sure on the exact process here (whether the contents of the
tag are fine and we're "just" missing a description, ...) so I'll let
Neil comment on this.

The PWM part is backwards compatible. The bindings are upstream since
commit 5fd61cc28171 ("dt-bindings: pwm: amlogic: Add a new binding for
meson8 pwm types").
The mentioned pinctrl binding / driver is completely new for the A4
SoCs, so there's nothing to be backwards compatible with.

Neil, for me it's fine to skip this one for 6.15 if it causes too much
work on your side.
Using the old PWM bindings for another release won't hurt anyone.
And I think the same goes for A4 pinctrl support as well as GPIO
interrupt controller nodes for A4/S5.


Best regards,
Martin

Sure, I can strip out the pinctrl DT changes, since they can definitely wait another cycle.

For the PWM bindings, they are in -next for a long time already, and
everything was done to keep the old bindings still work over time.

So we're pretty confident it works fine since it has run over CI for
multiple months.

I'll resent a new PR without the new A4 pinctrl changes.

Thanks,
Neil
