drm/dp: Add helper to set LTTPRs in transparent mode

2025-02-25T16:33:31Z

According to the DisplayPort standard, LTTPRs have two operating modes: - non-transparent - it replies to DPCD LTTPR field specific AUX requests, while passes through all other AUX requests - transparent - it passes through all AUX requests. Switching between this two modes is done by the DPTX by issuing an AUX write to the DPCD PHY_REPEATER_MODE register. Add a generic helper that allows switching between these modes. Also add a generic wrapper for the helper that handles the explicit disabling of non-transparent mode and its disable->enable sequence mentioned in the DP Standard v2.0 section 3.6.6.1. Do this in order to move this handling out of the vendor specific driver implementation into the generic framework.

drm: Fix DSC BPP increment decoding

2025-02-13T08:20:30Z

Starting with DPCD version 2.0 bits 6:3 of the DP_DSC_BITS_PER_PIXEL_INC DPCD register contains the NativeYCbCr422_MAX_bpp_DELTA field, which can be non-zero as opposed to earlier DPCD versions, hence decoding the bit_per_pixel increment value at bits 2:0 in the same register requires applying a mask, do so.
