openwrt/target/linux/bcm27xx/patches-6.6/950-0870-ARM-dts-Standardise-downstream-Pi-GPIO-pin-names.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches 
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0870/1085] ARM: dts: Standardise downstream Pi GPIO pin names
Standardise the names of the pins on the 40-pin GPIO header. This makes
it easier to use libgpiod (and the gpiod tools) for cross-platform GPIO
manipulation.
