From e7c21940463cf02bdefb4edd38d61dd7c589bb5c Mon Sep 17 00:00:00 2001 From: Sergio Paracuellos Date: Tue, 20 Sep 2022 07:20:50 +0200 Subject: dt-bindings: i2c: migrate mt7621 text bindings to YAML SoC MT7621 I2C bindings used text format, so migrate them to YAML. There are some additions to the binding that were not in the original txt file. This binding is used in MT7621 and MT7628a Ralink SoCs. To properly match both dts nodes in tree we need to add to the schema 'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and 'reset-names' use 'i2c' as string so maintain that as const in the schema. Also, Properly update MAINTAINERS file to align the changes.
