Laying the groundwork for the AMD DAL display driver.
This patch includes the basic services and defines basic
types required by the display driver, such as:
- ASIC register access
- VBIOS access
- Vector and flat_set data structures
- Display signal types
- ASIC versions and IDs
- HW IDs
- Logging functionality
This patch adds Kconfig options to enable the DAL
display driver.
- DRM_AMD_DAL
- DRM_AMD_DAL_VBIOS_PRESENT
- DRM_AMD_DAL_DCE11_0
- DRM_AMD_DAL_DCE10_0
- DEBUG_KERNEL_DAL
