Subject: [PATCH 038/552] pinctrl-bcm2835: Set base to 0 give expected gpio
numbering
Signed-off-by: Noralf Tronnes <notro@tronnes.org>
SQUASH: pinctrl: bcm2835: Set base for bcm2711 GPIO to 0
Without this patch GPIOs don't seem to work properly, primarily
noticeable as broken LEDs.
Squash with "pinctrl-bcm2835: Set base to 0 give expected gpio numbering"
