Subject: [PATCH 0/4] pinctrl: bcm2835: Add support for all BCM2711 GPIOs
Date: Sat, 8 Feb 2020 14:02:51 +0100 [thread overview]
Message-ID: <1581166975-22949-1-git-send-email-stefan.wahren@i2se.com> (raw)
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
