   4 Subject: [PATCH] arm64: dts: rockchip: add rk3588 gpio aliases to soc dtsi
   5
   6 The gpio controllers on rk3588 are named gpio0 - gpio4. Board schematics
   7 also use these exact numbers and we want those names to also reflect
   8 in the OS devices because everything else would just cause confusion.
   9 Userspace gpio access is a thing afterall.
  10
  11 To prevent each board repeating their list of gpio aliases, define them
  12 in the soc dtsi, as previous Rockchip soc like the rk356x do already.
