From 2f52be8b8def41e74fa9dce585d7819bab28ec11 Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Mon, 28 Nov 2022 01:02:25 -0600 Subject: video: sunxi: dw-hdmi: Probe driver by compatible Currently the sunxi dw-hdmi driver is probed unconditionally, even if there is no such device. Switch the driver to probing via a compatible string. This brings many benefits; the driver is only probed when needed, and now it can read the DT node.
