[PATCH v2 1/3] ARM: dts: Modify GPIO table for Asrock X570D4U BMC

Renze Nicolai renze at rnplus.nl
Wed Apr 3 06:28:51 PDT 2024


Restructure GPIO table to fit maximum line length.

Fix mistakes found while working on OpenBMC
userland configuration and based on probing
the board.

Schematic for this board is not available.
Because of this the choice was made to
use a descriptive method for naming the
GPIOs.

 - Push-pull outputs start with output-*
 - Open-drain outputs start with control-*
 - LED outputs start with led-*
 - Inputs start with input-*
 - Button inputs start with button-*
 - Active low signals end with *-n
