  Changes in v4:
 - Added a fix for MT8192 Vgpu voltage constraints
 - Changed constraints for MT8192 VSRAM-GPU to reflect the maximum
   achievable voltage as per the actual vsram-vgpu relation constraint

Changes in v3:
 - Changed MT8186 compatibles for new bindings
 - Added min/max voltage overrides for vgpu/vsram_gpu on
   mt8183-pumpkin and evb as suggested by Chen-Yu
 - Cosmetic fixes for "arm64: dts: mediatek: mt8192: Add GPU nodes"

Changes in v2:
 - Changed MT8186 to use only two power domains for the GPU.

We finally have working GPU DVFS on MediaTek SoCs.
On Panfrost.
For real.
...and the best part is that it's going upstream.

In order to get GPU DVFS working, it was necessary to satisfy a
specific constraint (which is different, depending on the SoC)
between two regulators: GPU VCORE and GPU SRAM.
This was done through adding the mtk-regulator-coupler driver,
which transparently manages the voltage relation between these
two vregs, hence completely eliminating the need to manage these
regulators in the Panfrost driver; this solves the long standing
issue with devfreq+opp tables not supporting managing voltages
for two regulators per opp entry out of the box, due to which
we never got GPU DVFS on those SoCs, often locking them out to
a low GPU frequency.

This changes. Right now!

Tested on MT8192, MT8195 Chromebooks.

This series depends on [1].

Series looks good but from my understanding has a dependency on:
[PATCH v4 00/12] Panfrost: Improve and add MediaTek SoCs support 
(https://lore.kernel.org/linux-mediatek/20230228102610.707605-1-angelogioacchino.delregno@collabora.com/)

Did I get that right?

Yes you got it right - without the mentioned series, this one will do nothing
at all (and will also fail binding checks, as the bindings are introduced in
that other series).

Please also let me test them on MT8183 and MT8186 before merging them.

Of course, I'll wait for your tested-by tags then.

Tested-by: Chen-Yu Tsai <wenst@chromium.org>

on MT8183, MT8186, MT8192 and MT8195 Chromebooks.

BTW, Angelo, I see that Panfrost keeps the GPU regulator enabled, but
the power domains, and thus the SRAM regulator, get powered off when
the GPU is not in use. There doesn't seem to be any damaging effects,
but I worry about idle power consumption.

Yes I've seen that as well... and it's true there will be some unwanted
small power leakage.

Though, I would propose to do things step by step. Right now, as it is, the
platform is fully stable... so let's get this in so that we estabilish a
known working baseline... what I have in mind is, exactly:

1. Get Panfrost+DVFS working on current platforms; then
2. Resolve the GPU binning situation (eFuses -> opp-supported-hw)
3. Improve the power consumption (all GPU regulators off during suspend)

Thanks for all the valuable testing and support!

Cheers,
Angelo

Hello Matthias,

The Panfrost driver patches were just queued to drm-misc-next [1], can you please
pick this fully reviewed and fully tested series, so that we get them both to land
at the same time?

Many thanks!
