[PATCH 0/6] arm64: dts: broadcom: bcm2712: add missing nodes

[Gregor Herburger]

Hi,

This series addresses some missing nodes for the bcm2712 raspberry pi 5
and includes some fixes for the -d revision.
I identified these while working on the camera interfaces on the
rapsberry pi 5. All the drivers were already there. Only the devicetree
nodes were missing.
As I don't have access to any datasheets, these changes were ported from
the downstream tree (https://github.com/raspberrypi/linux/).

[PATCH 5/6] arm64: dts: broadcom: bcm2712-d-rpi-5-b: add fixes for pinctrl/pinctrl_aon

[Gregor Herburger]

On the -d revision of the bcm2712 the pinctrl differs from the c0
revision. The driver already supports both and distinguishes the two
with the compatible string.

Update the compatible string and reg length to reflect the different
pinctrl.
