Start enabling DP 2.0 features. It's not complete, but it's a good
start, and should not conflict with anything existing.
Jani Nikula (17):
drm/dp: add DP 2.0 UHBR link rate and bw code conversions
drm/dp: use more of the extended receiver cap
drm/dp: add LTTPR DP 2.0 DPCD addresses
drm/dp: add helper for extracting adjust 128b/132b TX FFE preset
drm/i915/dp: use actual link rate values in struct link_config_limits
drm/i915/dp: read sink UHBR rates
drm/i915/dg2: add TRANS_DP2_CTL register definition
drm/i915/dg2: add DG2+ TRANS_DDI_FUNC_CTL DP 2.0 128b/132b mode
drm/i915/dg2: add TRANS_DP2_VFREQHIGH and TRANS_DP2_VFREQLOW
drm/i915/dg2: add DG2 UHBR source rates
drm/i915/dp: add max data rate calculation for UHBR rates
drm/i915/dp: use 128b/132b TPS2 for UHBR+ link rates
drm/i915/dp: select 128b/132b channel encoding for UHBR rates
drm/i915/dg2: configure TRANS_DP2_CTL for DP 2.0
drm/i915/dg2: use 128b/132b transcoder DDI mode
drm/i915/dg2: configure TRANS_DP2_VFREQ{HIGH,LOW} for 128b/132b
drm/i915/dg2: update link training for 128b/132b
