My long term plan is to reference all post-setup VBT child device
details through the encoder. We can add an (opaque) encoder->child
pointer, and forgo the dance to get to the relevant VBT details. This
will be helpful in, for example, adding support for multiple local
panels; the data must be made encoder specific instead of just using
i915->vbt.edp or i915->vbt.dsi directly.

The i915->vbt.ddi_port_info[] array stands in the way. Start hiding it
in intel_bios.c. We do gain a lot of intel_bios_*() accessors which may
seem noisy. But it seems to me this is a helpful iterative step no
matter what.


Jani Nikula (9):
  drm/i915/bios: add intel_bios_max_tmds_encoder()
  drm/i915/bios: add intel_bios_hdmi_level_shift()
  drm/i915/bios: intel_bios_dp_boost_level()
  drm/i915/bios: intel_bios_hdmi_boost_level()
  drm/i915/bios: add intel_bios_dp_max_link_rate()
  drm/i915/bios: add intel_bios_alternate_ddc_pin()
  drm/i915/bios: add intel_bios_port_supports_*()
  drm/i915/bios: check port presence based on child device
  drm/i915: use intel_bios_is_port_present()
