From aefdaa15e54c092709cb926a4b2732986386ef34 Mon Sep 17 00:00:00 2001 From: "Lowry Li (Arm Technology China)" Date: Tue, 17 Sep 2019 11:25:44 +0000 Subject: [PATCH] drm/komeda: Adds register dump support for gcu, lup and dou Adds to support register dump on lpu and dou of pipeline and gcu on D71 Changes since v1: - For a constant format without additional arguments, use seq_puts() instead of seq_printf().
