From f944b15966d410fd81f6051a836f86d5263f617e Mon Sep 17 00:00:00 2001 From: Maxime Jourdan Date: Tue, 4 Jun 2019 22:26:19 +0200 Subject: [PATCH] video: meson: hdmi-supply regulator should be optional Some boards don't have such a regulator, and don't need one to enable HDMI display. Make it optional, fixing hdmi display for those boards. Also surround the regulator code with a config check on DM_REGULATOR.
