From b891d5e46c96b0a41a5b09024794c631ee77c37b Mon Sep 17 00:00:00 2001 From: Dhinakaran Pandiyan Date: Fri, 23 Feb 2018 14:15:15 -0800 Subject: drm/i915/psr: New power domain for AUX IO. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PSR on CNL requires AUX IO wells to be kept on and the existing AUX domain for AUX-A enables DC_OFF well too. This is not required, so add a new AUX_IO_A domain for AUX-A to allow DC states to remain enabled. Other AUX channels re-use the existing AUX domains. v4: Reword comment (Rodrigo and Ville) Rename _get and _put functions to include aux_io substring(Rodrigo) Remove unnecessary diff that got included. v3: Extract aux domain selection into a function (Ville) v2: Add AUX IO domain only for AUX-A Rebased on top of Ville's AUX series.
