Subject: [PATCH] arm: dts: imx53-qsb-hdmi: Disable panel instead of deleting node
Date: Tue, 14 May 2024 11:07:18 +0800	[thread overview]
Message-ID: <20240514030718.533169-1-victor.liu@nxp.com> (raw)

We cannot use /delete-node/ directive to delete a node in a DT
overlay.  The node won't be deleted effectively.  Instead, set
the node's status property to "disabled" to achieve something
similar.

Fixes: eeb403df953f ("ARM: dts: imx53-qsb: add support for the HDMI expander")
