Subject: [PATCH v3 0/6] Add Unisoc's drm kms module
Date:   Tue,  5 Jan 2021 21:46:01 +0800
Message-Id: <1609854367-2720-1-git-send-email-kevin3.tang@gmail.com>
Precedence: bulk

ChangeList:
RFC v1:
1. only upstream modeset and atomic at first commit. 
2. remove some unused code;
3. use alpha and blend_mode properties;
3. add yaml support;
4. remove auto-adaptive panel driver;
5. bugfix

RFC v2:
1. add sprd crtc and plane module for KMS, preparing for multi crtc&encoder
2. remove gem drivers, use generic CMA handlers
3. remove redundant "module_init", all the sub modules loading by KMS

RFC v3:
1. multi crtc&encoder design have problem, so rollback to v1

RFC v4:
1. update to gcc-linaro-7.5.0
2. update to Linux 5.6-rc3
3. remove pm_runtime support
4. add COMPILE_TEST, remove unused kconfig
5. "drm_dev_put" on drm_unbind
6. fix some naming convention issue
7. remove semaphore lock for crtc flip
8. remove static variables

RFC v5:
1. optimize encoder and connector code implementation
2. use "platform_get_irq" and "platform_get_resource"
3. drop useless function return type, drop unless debug log
4. custom properties should be separate, so drop it
5. use DRM_XXX replase pr_xxx
6. drop dsi&dphy hal callback ops
7. drop unless callback ops checking
8. add comments for sprd dpu structure

RFC v6:
1. Access registers via readl/writel
2. Checking for unsupported KMS properties (format, rotation, blend_mode, etc) on plane_check ops
3. Remove always true checks for dpu core ops

RFC v7:
1. Fix DTC unit name warnings
2. Fix the problem of maintainers
3. Call drmm_mode_config_init to mode config init
4. Embed drm_device in sprd_drm and use devm_drm_dev_alloc
5. Replace DRM_XXX with drm_xxx on KMS module, but not suitable for other subsystems
6. Remove plane_update stuff, dpu handles all the HW update in crtc->atomic_flush
7. Dsi&Dphy Code structure adjustment, all move to "sprd/"

v0:
1. Remove dpu_core_ops stuff layer for sprd drtc driver, but dpu_layer need to keeping.
   Because all the HW update in crtc->atomic_flush, we need temporary storage all layers for
   the dpu pageflip of atomic_flush.
2. Add ports subnode with port@X.

v1:
1. Remove dphy and dsi graph binding, merge the dphy driver into the dsi.
2. Add commit messages for Unisoc's virtual nodes.

v2:
1. Use drm_xxx to replace all DRM_XXX.
2. Use kzalloc to replace devm_kzalloc for sprd_dsi/sprd_dpu structure init.
3. Remove dpu_core_ops midlayer.

v3:
1. Remove dpu_layer midlayer and commit layers by aotmic_update

Kevin Tang (6):
  dt-bindings: display: add Unisoc's drm master bindings
  drm/sprd: add Unisoc's drm kms master
  dt-bindings: display: add Unisoc's dpu bindings
  drm/sprd: add Unisoc's drm display controller driver
  dt-bindings: display: add Unisoc's mipi dsi controller bindings
  drm/sprd: add Unisoc's drm mipi dsi&dphy driver
