      drm/i915/params: switch to device specific parameters · 8a25c4be
      由 Jani Nikula 提交于 
      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.

      drm/i915/rkl: provide port/phy mapping for vbt · 4628142a
      由 Lucas De Marchi 提交于 
      RKL uses the DDI A, DDI B, DDI USBC1, DDI USBC2 from the DE point of
view, so all DDI/pipe/transcoder register use these indexes to refer to
them. Combo phy and IO functions follow another namespace that we keep
as "enum phy". The VBT in theory would use the DE point of view, but
that does not happen in practice.

Provide a table to convert the child devices to the "correct" port
numbering we use. Now this is the output we get while reading the VBT:

DDIA:
[drm:intel_bios_port_aux_ch [i915]] using AUX A for port A (VBT)
[drm:intel_dp_init_connector [i915]] Adding DP connector on [ENCODER:275:DDI A]

[drm:intel_hdmi_init_connector [i915]] Using DDC pin 0x1 for port A (VBT)

      drm/i915/display: Make WARN* drm specific where drm_device ptr is available · f4224a4c
      由 Pankaj Bharadiya 提交于 
      drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

      drm/i915/gen11: Allow usage of all GPIO pins · 5a6b7ef6
      由 Matt Roper 提交于 
      Our pin mapping tables for ICP and MCC currently only list the standard
GPIO pins used for various output ports.  Even through ICP's standard
pin usage only utilizes pins 1, 2, and 9-12, and MCC's standard pin
usage only uses pins 1, 2, and 9, these platforms do still have GPIO
registers to address pins in the range 1-3 and 9-14.  OEM's may remap
GPIO usage in non-standard ways (and provide the actual mapping via VBT
settings), so we shouldn't exclude pins on these platforms just because
they aren't part of the standard mappings.

TGP's standard pin tables contains all the possible pins, so let's
rename them to "icp" and use them for all PCH >= PCH_ICP.  This will
prevent intel_gmbus_is_valid_pin from rejecting non-standard pin usage
that an OEM specifies via the VBT.

Note that this will cause pin 9 to be labeled as "tc1" instead of "dpc"
in debug messages on platforms with the MCC PCH, but that may actually
help avoid confusion since the text strings will now be the same on all
gen11+ platforms instead of being different on just EHL.

v2: Drop now-unused MCC_DDC_BUS_DDI_* names.

v3: We want to compare against INTEL_PCH_TYPE, not INTEL_PCH_ID.
