Subject: [RFC v3 1/8] dt-bindings: display: convert ingenic,lcd.txt to ingenic,lcd.yaml
Date: Sun, 29 Mar 2020 19:35:47 +0200 [thread overview]
Message-ID: <a75c77fa8528f44832993f9780ae4ea409125a90.1585503354.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1585503354.git.hns@goldelico.com>
and add compatible: jz4780-lcd, including an example how to
configure both lcd controllers.
Also fix the clock names and examples.
Based on work by Paul Cercueil <paul@crapouillou.net> and
Sam Ravnborg <sam@ravnborg.org>
