c0a950d182 drm/i915/bios: add intel_bios_encoder_data to encoder, use for iboost
Add intel_bios_encoder_data pointer to encoder, and use it for hdmi and
dp iboost. For starters, we only set the encoder->devdata for DDI
encoders, i.e. we can only use it for data that is used by DDI encoders.

f08fbe6a8c drm/i915/bios: start using intel_bios_encoder_data for Type-C USB and TBT
Stop caching the information in ddi_port_info. We're phasing out
ddi_port_info usage completely, and prefer using the VBT child device
information directly using the provided helpers.

v2:
- Remove supports_typec_usb & supports_tbt from ddi_vbt_port_info (Lucas)

45c0673aac drm/i915/bios: start using the intel_bios_encoder_data directly
Start using struct intel_bios_encoder_data directly. We'll start
sanitizing the child device data directly as well, instead of the cached
data in ddi_port_info[]. The one downside here is having to store a
non-const pointer back to intel_bios_encoder_data.

Eventually we'll be able to have a direct pointer from encoder to
intel_bios_encoder_data, removing the need to go through the
ddi_port_info[] array altogether. And we'll be able to remove all the
cached data in ddi_port_info[].

v2:
- Remove supports_dp and supports_edp from ddi_port_info too
- Add devdata != NULL check in intel_bios_is_port_edp()

dbc137422b drm/i915/bios: save a higher level pointer in ddi_vbt_port_info[]
We'll be needing the intel_bios_encoder_data pointer going forward, and
it's just easier to store the higher level pointer in the
ddi_vbt_port_info[] array.

aaab24bb25 drm/i915/display: Handle lane polarity for DDI port
Lane Reversal is required for some of the DDI ports. This information
is populated in VBT and driver should read the same and set the
polarity while enabling the port. This patch handles the same.

It helps fix a display blankout issue on DP ports on certain
platforms.

1bf2f3bf29 drm/i915/bios: add support for querying DSC details for encoder
Add function for retrieving the DSC data for an encoder.

Initially, this is DSI specific, as DP does not use VBT settings for DSC
at all. It's also not very pretty.

In the future we might have a pointer from encoder to the child device,
which would make the child device list query here so much more sensible.

v3:
- use crtc_state instead of pipe_config
- return true by default from intel_bios_get_dsc_params()
- expand the comment about rc_buffer_block_size and rc_buffer_size

v2:
- make more robust, debug log errors better

v4:
  commit msg is rephrased.
v5:
  copyright year is updated [Tomas]

5ccf2027bb drm/i915: Check backlight type while doing eDP backlight initializaiton
If LFP backlight type setting from VBT was "VESA eDP AUX Interface".
Driver should check panel capability and try to initialize aux backlight.
No matter i915_modparams.enable_dpcd_backlight was enabled or not.

v2: access dev_priv->vbt.backlight.type directly and remove unused function.
v3: 1. Modify i915.enable_dpcd_backlight type from bool to int and give default
       value as 0 (disable).
    2. Add a judgement to check LFP backlight type was aux interface or not.
