Hi,
To support a plethora of MIPI panels, the VBT has been enhanced to support
multiple panels in a generic manner. This involves adding one MIPI configuration
block (#52) which provide all panel specific configuration data along with the
dphy configuration information as per panel/tcon specs. Also a sequence (#53) block
is added to provide required sequences for panel enabling.
The driver will use this parsed data to enable the panel which is described in these
two block. The i-g-t tool intel_parse_bios changes to parse these new block is WIP.
The generic driver will be as one of sub-encoder driver in the existing design to support
MIPI. Followup patches for this driver will come next.
v2: Address review comments from Jani Nikula
- update datastructures and related code to enable cleaner and simpler code
- using kmemdup instead of kmalloc and memcpy
- Proper error detection during parsing MIPI sequence block
Regards
Shobhit
