From bb59462e414f8c0c55800064e9be4c596ae6898d Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 15 Dec 2021 20:45:29 -0800 Subject: [PATCH] arm64: dts: qcom: sc7180: Add board regulators for MIPI camera trogdor boards Some trogdor boards have on-board regulators for the MIPI camera components. Add nodes describing these regulators so boards with these supplies can consume them.
