- Add simplefb device-tree node which is required to show
early boot-up logs on display when UEFI initializes display
- Default status of the node is disabled by default in DT
and is enabled dynamically by UEFI only when it initializes display
- Following information is contained in the simplefb node.
i) Add display power-domain property. Without this, genpd driver
will powergate the display power-domain during kernel boot.
ii) Add all display clocks handles (even if not enabled by UEFI).
Without this, kernel CCF will disable clocks during kernel boot-up.
iii) Add reference to fb reserved region memory node.
fb reserved region node is updated by UEFI driver when it
initializes display.
iv) Add width, height, stride properties initialized to
"0" and format of display surface initialized to 32bit RGB pixel
format. These are updated by UEFI when it initializes display as
per UEFI display surface properties.
