[PATCH v3 04/15] arm64: dts: imx8mm-phycore-som: Assign regulator for dsi to lvds bridge

From: Andrej Picej <hidden>
Date: 2025-02-18 07:42:47
Also in: imx, linux-devicetree, lkml
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

From: Yashwanth Varakala <redacted>

Add a missing voltage regulator of 1.8v to the sn65dsi83
(dsi_lvds bridge) node. Due to the absence of this regulator, a fallback
dummy regulator is used and that triggers a warning message from the
kernel. Assigning the appropriate regulator avoids the warning.
