[Intel-gfx] [PATCH 0/1] HDMI 2.0/DP1p62Gbps skew violation when there is skew between DL PCLK

[Mitul Golani]

When doing type-C PHY voltage swing programming for HDMI and DP 1.62Gbps,
program DKLP_PCS_GLUE_TX_DPCNTL2[loadgen_sharing_pmd_disable] to '1'.
For other DP frequencies, program DKLP_PCS_GLUE_TX_DPCNTL2[loadgen_sharing_pmd_disable]
to '0'.

This Workaround is specific to Display Version 13
