From 13047a092c6d3f23b7d684b5b3fe46b2b50423b9 Mon Sep 17 00:00:00 2001 From: Edmund Dea Date: Tue, 20 Apr 2021 15:31:53 -0700 Subject: [PATCH] drm/kmb: Remove clearing DPHY regs Don't clear the shared DPHY registers common to MIPI Rx and MIPI Tx during DSI initialization since this was causing MIPI Rx reset. Rest of the writes are bitwise, so will not affect Mipi Rx side.
