Merge tag 'arm-soc/for-6.10/devicetree' of https://github.com/Broadcom/stblinux into soc/dt
This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 6.10, please pull the following:
- Laurent converts the Raspberry Pi firmware DT binding to YAML, updates
the firmware driver to use the proper 'struct device' reference for
DMA mappings and drops unneeded properties from the DT node and
finishes by removing the duplicate firmware-clocks property to
bcm2835-rpi.dtsi. He also added support for the CAM1 camera interface
regulator.
- Uwe adds a pinctrl-based multiplexing description to allow the use of
I2C0 pins to allow usage between the 40-pin Raspberry Pi header and
the CSI and DSI connectors. He then describes the PCF85063 RTC device
available on the CM4 I/O board making use of that pinctrl-based
muxing.
- Arinc updates the Asus RT-AC3100 and RT-AC88U DTs to have proper LED
colors and function properties, NVMEM MAC addresses and removes
duplicates and unnecessary properties and does a few Device Tree
cleanups.. He then adds support for the Asus RT-AC3200 (BCM4709-based)
and RT-AC3500 routers.
- Jean-Michel adds DT nodes for the CSI Unicam camera interfaces on the
Raspberry Pi 4 / BCM2711 SoCs
- Florian adds support for the Ethernet LEDs on Raspberry Pi 4 B and
Raspberry Pi 4 CM boards.
