From mboxrd@z Thu Jan 1 00:00:00 1970 From: Leonard Crestez Subject: [PATCH v2 0/2] Fix imx6sl display power domain Date: Mon, 9 Jul 2018 15:23:00 +0300 Message-ID: Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Lucas Stach , Shawn Guo , Fabio Estevam Cc: Robin Gong , Anson Huang , Dong Aisheng , linux-pm@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, linux-imx@nxp.com, kernel@pengutronix.de List-Id: linux-pm@vger.kernel.org Right now the imx6sl display power domain is automatically shut down during boot so lcd doesn't work at all. This has been broken for a while with old gpc bindings, since nobody noticed fix by converting to new bindings. Link to v1: https://lkml.org/lkml/2018/6/5/689 There is also a nasty errata here, treat it like on 6qp. Previous version included a patch to improve lcdif power management, but since ERR006287 effectively disables runtime PM for display it is no longer strictly required. This doesn't depend on other GPC patches I sent either, it's an unrelated fix.
