2025-06-18drm/amd/display: Deprecate Loading Bounding Box From DMUB On DCN4Austin Zheng
[WHY] dml2_soc_bb struct can continuously receive updates for future ASICs. Alignment issues may arise since VBIOS DMCUB contains an older version of the SOC BB. Populating the bounding box with values from DMCUB is no longer necessary since values such as UCLK will be overridden by values acquired by PMFW anyways. [HOW] Use bb_from_dmub to store DCN specific bounding box parameters in DMCUB. Add helpers to translate DCN specific struct to the corresponding dml2_soc_bb field. To avoid alignment issues: Deprecate applying DMCUB SoC BB for DCN4 For future projects: Create a flattened struct containing all sensitive parameters in the bounding box. New parameters can be added to the bottom of the new struct as needed.

2025-06-18drm/amd/display: Get LTTPR IEEE OUI/Device ID From Closest LTTPR To HostMichael Strauss
[WHY] These fields are read for the explicit purpose of detecting embedded LTTPRs (i.e. between host ASIC and the user-facing port), and thus need to calculate the correct DPCD address offset based on LTTPR count to target the appropriate LTTPR's DPCD register space with these queries. [HOW] Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a laptop) will always be addressible using the max LTTPR count seen by the host. Therefore we simply need to use a recently added helper function to calculate the correct DPCD address to target potentially embedded LTTPRs based on the received LTTPR count.
