Hi Florian,
I think patches 05/10 ("ARM: dts: bcm2835-rpi: Move duplicate
firmware-clocks to bcm2835-rpi.dtsi"), 07/10 ("ARM: dts: bcm2711-rpi:
Add pinctrl-based multiplexing for I2C0"), 08/10 ("ARM: dts:
bcm2711-rpi-cm4-io: Add RTC on I2C0") and 09/10 ("ARM: dts:
bcm2711-rpi-4-b: Add CAM1 regulator") are ready for you to merge. This
would help reducing further iterations of this series.
