drm/i915/display: prefer dig_port to reference intel_digital_port
We have a mix of dport, intel_dport, intel_dig_port and dig_port to reference a intel_digital_port struct. Numbers are around 5 intel_dport 36 dport 479 intel_dig_port 352 dig_port Since we already removed the intel_ prefix from most of our other structs, do the same here and prefer dig_port. v2: rename everything in i915, not just a few display sources and reword commit message (from Matt Roper) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200701045054.23357-1-lucas.demarchi@intel.com |

drm/i915/params: switch to device specific parameters
Start using device specific parameters instead of module parameters for most things. The module parameters become the immutable initial values for i915 parameters. The device specific parameters in i915->params start life as a copy of i915_modparams. Any later changes are only reflected in the debugfs. The stragglers are: * i915.force_probe and i915.modeset. Needed before dev_priv is available. This is fine because the parameters are read-only and never modified. * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and I915_STATE_WARN_ON would result in massive and ugly churn. This is handled by not exposing the parameter via debugfs, and leaving the parameter writable in sysfs. This may be fixed up in follow-up work. * i915.inject_probe_failure. Only makes sense in terms of the module, not the device. This is handled by not exposing the parameter via debugfs. v2: Fix uc i915 lookup code (Michał Winiarski) Cc: Juha-Pekka Heikkilä <juha-pekka.heikkila@intel.com> Cc: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20200618150402.14022-1-jani.nikula@intel.com |

drm/i915: Fix the i915_dsc_fec_support debugfs file for DP MST connectors
DSC is not supported on DP MST streams so just don't add this entry for MST connectors. This also fixes an OOPS, caused by the encoder->digport cast, which is not valid for MST encoders. v2: - Check encoder, which is unset for an MST connector, before it gets enabled. v3: - Just don't add this debugfs file for MST connectors.

drm: Nuke mode->vrefresh
Get rid of mode->vrefresh and just calculate it on demand. Saves
a bit of space and avoids the cached value getting out of sync
with reality.
Mostly done with cocci, with the following manual fixups:
- Remove the now empty loop in drm_helper_probe_single_connector_modes()
- Fix __MODE() macro in ch7006_mode.c
- Fix DRM_MODE_ARG() macro in drm_modes.h
- Remove leftover comment from samsung_s6d16d0_mode
- Drop the TODO

New i915_pm_lpsp igt solution approach relies on connector specific debugfs attribute i915_lpsp_capability, it exposes whether an output is capable of driving lpsp. v2: - CI fixup. v3: - register i915_lpsp_info only for supported connector.

drm/dp_mst: Remove drm_dp_mst_has_audio()
Drive-by fix I noticed the other day - drm_dp_mst_has_audio() only ever made sense back when we still had to validate ports before accessing them in order to (attempt to) avoid NULL dereferences. Since we have proper reference counting that guarantees we always can safely access the MST port, there's no use in keeping this function around as all it does is validate the port pointer before checking the audio status. Note - drm_dp_mst_port->has_audio is technically protected by drm_device->mode_config.connection_mutex, since it's only ever updated from drm_dp_mst_get_edid(). Additionally, we change the declaration for port in struct intel_connector to be properly typed, so we can directly access it.

drm/i915: Unify the DPLL ref clock frequency tracking
All platforms using the shared DPLL framework use 3 reference clocks for their DPLLs: SSC, non-SSC and DSI. For a more unified way across platforms store the frequency of these ref clocks as part of the DPLL global state. This also allows us to keep the HW access reading out the ref clock value separate from the DPLL frequency calculation that depends on the ref clock. For now add only the SSC and non-SSC ref clocks, as the pre-ICL DSI code has its own logic for calculating DPLL parameters instead of the shared DPLL framework. v2: - Apply the ICL combo PHY PLL ref_clock/2 adjustment during the frequency->PLL param conversion direction as well.

drm/i915/display: use intel_de_*() functions for register access
The implicit "dev_priv" local variable use has been a long-standing pain point in the register access macros I915_READ(), I915_WRITE(), POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW(). Replace them with the corresponding new display engine register accessors intel_de_read(), intel_de_write(), intel_de_posting_read(), intel_de_read_fw(), and intel_de_write_fw().
