I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/57139
to look at the new patch set (#21).
Change subject: soc/intel/common/tcss: Optimize USB-C DP flow and code structure ......................................................................
soc/intel/common/tcss: Optimize USB-C DP flow and code structure
HPD event may not be ready when configuring TCSS mux for DP, check if any DP device is connected and wait for HPD ready before TCSS configuration. Remove unnecessary dependency on mainboard functions, use generic interface which provides USB-C mux operations.
BUG=b:192947843 TEST=select ENABLE_TCSS_DISPLAY_DETECTION in Kconfig.name for Brya. Build coreboot and update your Brya. Boot Brya with USB-C display connected, you should find `HPD ready after %lu ms` and `Port C%zd is configured to DP mode!` in coreboot log. Display should show screen in developer mode or recovery mode.
