[Intel-gfx] [PATCH 00/10] drm/i915: Prep work for vbt.ports[] nukage

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We need to get rid of the vbt.ports[] array. The main
reason being the bogus VBTs found on many ADL laptops
that declare both eDP+HDMI child devices for the same
port. The goal is to probe each of those in order and
stick to the first one that works. But the vbt.ports[]
array gets populated before we do any output probing 
and, being indexed with the port, can't handle any
aliasing child devices.

Here's a bit of prep work to reduce our reliance on
vbt.ports[], mainly by expanding the encoder->devdata
(a direct pointer to the correct vbt child device from
the encoder) usage.

Ville Syrjälä (10):
  drm/i915: Pass the whole encoder to hotplug_enables()
  drm/i915: Move variables to loop context
  drm/i915: Replace intel_bios_is_lspcon_present() with
    intel_bios_encoder_is_lspcon()
  drm/i915: Replace intel_bios_is_lane_reversal_needed() with
    intel_bios_encoder_lane_reversal()
  drm/i915: Replace intel_bios_is_port_hpd_inverted() with
    intel_bios_encoder_hpd_invert()
  drm/i915: Consult the registested encoders for the ICL combo PHY w/a
  drm/i915: Populate encoder->devdata for g4x+ DP/HDMI ports
  drm/i915: Pass devdata to intel_bios_port_aux_ch()
  drm/i915: Iterate all child devs in intel_bios_is_port_present()
  drm/i915: Use encoder->devdata in eDP init
