Subject: [PATCH] overlays: pisound: Make button pins owned by card
|
|
|
|
The pisound overlay claims a number of GPIOs using a pinctrl node, but
|
|
for some reason hangs this claim on the main gpio node. This obscures
|
|
the ownership of the pins (as shown by gpioinfo and in the kernel logs)
|
|
and isn't scalable - only one overlay can use the trick at a time.
|
|
|
|
Change the overlay to make the pin ownership clear and avoid any future
|
|
conflicts, removing a bogus claim on pins_spi0 at the same time.
|
|
|
|
