RPM suspend/resume also supported on gfx platforms which doesn't have kms support and even on platforms without any connected display panel. There is no good reason to log rpm suspend/resume debug message with drm_dbg_kms() therefore changing it to drm_dbg(). Signed-off-by:

We need to start parsing stuff from the tail end of the LFP data block. This is made awkward by the fact that the fp_timing table has variable size. So we must use a bit more finesse to get the tail end, and to make sure we allocate enough memory for it to make sure our struct representation fits. v2: Rebase due to the preallocation of BDB blocks v3: Rebase due to min_size WARN relocation v4: Document BDB_LVDS_LFP_DATA vs. BDB_LVDS_LFP_DATA_PTRS order (Jani) Reviewed-by:

Ville Syrjälä authored
Modern VBTs no longer contain the LFP data table pointers block (41). We are expecting to have one in order to be able to parse the LFP data block (42), so let's make one up. Since the fp_timing table has variable size we must somehow determine its size. Rather than just hardcode it we look for the terminator bytes (0xffff) to figure out where each table entry starts. dvo_timing, panel_pnp_id, and panel_name are expected to have fixed size. This has been observed on various machines, eg. TGL with BDB version 240, CML with BDB version 231, etc. The most recent VBT I've observed that still had block 41 had BDB version 228. So presumably the cutoff (if an exact cutoff even exists) is somewhere around BDB version 229-231. v2: kfree the thing we allocated, not the thing+3 bytes v3: Do the debugprint only if we found the LFP data block v4: Fix t0 null check (Jani) Reviewed-by:

To avoid AUX timeouts and subsequent spurious hotplug interrupts, make sure that the first DPCD access during detection is a read from an LTTPR register. Some ADLP DP link configuration at least with multiple LTTPRs expects the first DPCD access during the LTTPR/DPCD detection after hotplug to be a read from the LTTPR range starting with DP_LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV. The side effect of this read is to put each LTTPR into the LTTPR transparent or LTTPR non-transparent mode. The lack of the above read may leave some of the LTTPRs in non-LTTPR mode, while other LTTPRs in LTTPR transparent or LTTPR non-transparent mode (for instance LTTPRs after system suspend/resume that kept their mode from before suspend). Due to the different AUX timeouts the different modes imply, the DPCD access from a non-LTTPR range will timeout and lead to an LTTPR generated hotplug towards the source (which the LTTPR firmware uses to account for buggy TypeC adapters with a long wake-up delay).

Move some checks into intel_dpll_crtc_compute_clock() from the caller. Avoids the caller from having to worry about all this crap.
