[PATCH v1 0/4] Add display support for SC7280 target

From: Krishna Manikandan
Date: Tue Apr 06 2021 - 01:10:23 EST


The changes in this series adds all the required support for display driver for
SC7280 target. In addition to the basic catalog changes, changes are added to
accommodate new registers for SC7280 target.

SC7280 target comes under next generation targets. The register differences in
SC7280 when compared to SC7180 are mentioned below:

- SC7280 uses UBWC3.0 and changes are added to program the ubwc static
registers properly

- Pingpong dither block offset value has changed for SC7280 family. Separate
sub block is defined for sc7280 pingpong block and changes are added to
handle this.

- Interface offsets are different for SC7280 family. These offset values are
used to access the interface irq registers. Changes are added to handle
this based on the target.

- A new register called CTL_FETCH_PIPE_ACTIVE is introduced in SC7280 family,
which tells the HW about the active pipes in the CTL path. Changes are
added to program this register based on the active pipes in the
current composition.

- Changes are added to program INTF_CONFIG2 properly since the reset value
of this register has changed in SC7280 family and we need to explicitly program
it with correct values to avoid wrong interface configuration.

- INTF_5 is added to intf configuration to support EDP.
