Subject: [PATCH v2 0/2] Bindings and DTS for Apple SoC GPUs

Hi.

This patch series adds the DT bindings and tree entries for the GPU
present in Apple M-series SoCs. The driver itself is in Rust and
upstream is currently missing several prerequisite bindings, so will
be sent later.

The kernel and m1n1 (bootloader) that are using those bindings are
available at the following branches:
Kernel: https://github.com/WhatAmISupposedToPutHere/linux/tree/starlight
m1n1: https://github.com/WhatAmISupposedToPutHere/m1n1/tree/bootloader-cal-blobs

Signed-off-by: Sasha Finkelstein <fnkl.kernel@...il.com>

Changes in v2:
- s/firmware-compat/firmware-abi/
- drop the agx-g13x compatible
- rework reserved regions
- Improved memory region and register descriptions
- Link to v1: https://lore.kernel.org/r/20250611-sgx-dt-v1-0-7a11f3885c60@gmail.com
