Subject: [PATCH V7 5/6] arm64: dts: imx8mp: add HDMI display pipeline
Date: Tue, 27 Feb 2024 16:04:39 -0600 [thread overview]
Message-ID: <20240227220444.77566-6-aford173@gmail.com> (raw)
In-Reply-To: <20240227220444.77566-1-aford173@gmail.com>
From: Lucas Stach <l.stach@pengutronix.de>
This adds the DT nodes for all the peripherals that make up the
HDMI display pipeline.

V7: Make PVI node disabled by default to avoid EPROBE_DEFER
V6: Make LCDIF3 disabled by default
V5: No change
V3: Re-ordered the HDMI parts to properly come after irqstree_hdmi
inside AIPS4. Change size of LCDIF3 and PVI to match TRM sizes
of 4KB.
V2: I took this from Lucas' original submission with the following:
Removed extra clock from HDMI-TX since it is now part of the
power domain
Added interrupt-parent to PVI
Changed the name of the HDMI tranmitter to fsl,imx8mp-hdmi-tx
Added ports to HDMI-tx
