Subject: [PATCH] arm64: dts: rockchip: add rk3588 gpio aliases to soc dtsi
|
||
|
|
|
||
|
|
The gpio controllers on rk3588 are named gpio0 - gpio4. Board schematics
|
||
|
|
also use these exact numbers and we want those names to also reflect
|
||
|
|
in the OS devices because everything else would just cause confusion.
|
||
|
|
Userspace gpio access is a thing afterall.
|
||
|
|
|
||
|
|
To prevent each board repeating their list of gpio aliases, define them
|
||
|
|
in the soc dtsi, as previous Rockchip soc like the rk356x do already.
