These patches coninue work started by AngeloGioacchino Del Regno in the previous cycle by further decoupling and dissecting MDSS and MDP drivers probe/binding paths.
This removes code duplication between MDP5 and DPU1 MDSS drivers, by merging them and moving to the top level.
Changes since v4: - Fixed the issue with MODULE_DEVICE_TABLE reported by robot - Fixed the comments accoring to suggestions of Stephen - Removed extra goto (Stephen's suggestion) - Break long kms->dev->dev->parent chains into cleaner dpu_dev/mdp_dev and mdss_dev to document device tree bindings. Add related comments. (Stephen's suggestion)
Changes since v3: - Rebased on top of current msm/msm-next - Fixed issue with enabling/disabling MDP4/MDP5 vs DSI driver (per Stephen's suggestion) - Reworked mdss_probe to remove extra platform_set_drvdata calls (per Stephen's suggestion) - Fixed a typo in the Kconfig (noted by Rob) - Added a patch to move component mastership from mdss to mdp5/dpu1 devices
Changes since v2: - Rebased on top of current msm/msm-next(-staging) - Allow disabling MDP4/MDP5/DPU/HDMI components (like we do for DP and DSI) - Made mdp5_mdss_parse_clock() static - Changed mdp5 to is_mdp5 argument in several functions - Dropped boolean device data from the mdss driver - Reworked error handling in msm_pdev_probe() - Removed unused header inclusion - Dropped __init/__exit from function prototypes
Changes since v1: - Rebased on top of [2] and [1]
