X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3d5c0c21d86fed05caeae43549e0c13ddd203c31;p=users%2Fhch%2Fmisc.git

arm64: dts: rockchip: add vcc3v3-lcd-s0 regulator to roc-rk3576-pc

This fixed regulator is described by the schematics as being part of the
baseboard and its output supply is then routed to the 30pin DSI connector
on the board.
