Rocket Lake (RKL) is another gen12 platform, so the driver support is
mostly a straightforward evolution of our existing Tiger Lake support.
One area of this patch series that's a bit non-intuitive and warrants
some extra explanation is the output handling. All four of RKL's output
ports use combo PHYs, but the hardware guys have recycled the naming
scheme from Tiger Lake. The DDI's are still named "A, B, TC1, and TC2"
even though none of them are actually connected to Type-C PHYs on this
platform. From a register offset perspective, these four DDIs are
effectively A, B, D, and E (skipping over the register range that would
usually be used for a "C" instance of the DDI). However the PHYs
attached to those DDIs do *not* skip the "C" instance, so we wind up
with the following output relationships:
DDI-A (port A) <-> PHY-A
DDI-B (port B) <-> PHY-B
DDI-TC1 (port D) <-> PHY-C
DDI-TC2 (port E) <-> PHY-D
Given that most of our past platforms have straight DDI==PHY mappings,
extra care is needed to ensure we use the proper namespace (port or phy)
when programming various output-related registers.
