From 48fa7c17d11a66a0a6202c3ac90c77907515304b Mon Sep 17 00:00:00 2001 From: Xu YiPing Date: Tue, 20 Aug 2019 23:06:17 +0000 Subject: [PATCH] drm: kirin: Move plane number and primay plane in driver data As part of refactoring the kirin driver to better support different hardware revisions, this patch moves the number of planes and the primary plane value to the kirin_drm_data structure This will make it easier to add support for new devices via a new kirin_drm_data structure.
