[PATCH v5 09/30] drm/dp: Add helpers to calculate the link BW overhead

2023-11-06 Thread Imre Deak
Add helpers drivers can use to calculate the BW allocation overhead - due to SSC, FEC, DSC and data alignment on symbol cycles - and the channel coding efficiency - due to the 8b/10b, 128b/132b encoding. On 128b/132b links the FEC overhead is part of the coding efficiency, so not accounted for in
