[Kevin Tang]

From: Kevin Tang <kevin.tang at unisoc.com>

ChangeList:
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

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

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

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

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

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
