The BCM2711 supports 58 GPIOs [1] by using the existing BCM2835 GPIO registers completely. So there is no need to change the binding. Patch 1 and 2 prepare the pinctrl driver to be extended to 58 GPIOs in Patch 3. I didn't want to squash them in order to make review as easy as possible. The final patch 4 assigns all SoC GPIOs a label as we already did for the older Raspberry Pi boards. Changes since RFC: - avoid using memcpy as suggested by Nicolas - drop unused entry from GPIO label legend [1] - https://github.com/raspberrypi/linux/issues/3101#issuecomment-573092294 Stefan Wahren (4): pinctrl: bcm2835: Drop unused define pinctrl: bcm2835: Refactor platform data pinctrl: bcm2835: Add support for all GPIOs on BCM2711 ARM: dts: bcm2711-rpi-4-b: Add SoC GPIO labels arch/arm/boot/dts/bcm2711-rpi-4-b.dts | 73 +++++++++++++++++++++++ drivers/pinctrl/bcm/pinctrl-bcm2835.c | 106 ++++++++++++++++++++++++++-------- 2 files changed, 155 insertions(+), 24 deletions(-) -- 2.7.4
