Subject: [PATCH v2 0/4] RK3588 GPU support

Hi,

Panthor has landed in linux-next including the DT bindings, so it is
time to add the necessary DT changes to support the GPU on RK3588.
This adds support at SoC level and support for the EVB1 as well as
the Rock 5B, which covers both variants found in RK3588 boards:

1. Having dedicated regulators for GPU core and GPU memory. This
   is handled by coupling both regulators.
2. Having a shared regulator for GPU core and GPU memory.

I prepared a branch with the GPU DT changes (and the panthor driver
changes for testing, consdering they do not clash) based on Heiko's
for-next branch:

https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/commits/rk3588-gpu

Changes since PATCHv1:
 - https://lore.kernel.org/all/20240325153850.189128-1-sebastian.reichel@collabora.com/
 - remove always-on from the GPU regulator in the Rock 5B patch
 - add comment to the always-on for the GPU regulators in the EVB1 patch
 - add explanation for the always-on in the EVB1 commit description

Greetings,

-- Sebastian
