From 63c4acfb8031fbcd50cf51cb94aaadc816d99c7c Mon Sep 17 00:00:00 2001 From: Johan Jonker Date: Tue, 11 May 2021 07:05:08 +0200 Subject: [PATCH] dt-bindings: gpio: convert rk3328-grf-gpio.txt to YAML Current dts files with RK3328 GRF 'gpio' nodes are manually verified. In order to automate this process rk3328-grf-gpio.txt has to be converted to YAML. Rename 'grf-gpio' nodename to 'gpio'.
