6400c215a1 drm/i915: modify max_bw to return index to intel_bw_info 
MTL uses the peak BW of a QGV point to lock the required QGV
point instead of the QGV index. Instead of passing the deratedbw
of the selected bw_info, return the index to the selected
bw_info so that either deratedbw or peakbw can be used based on
the platform.

v2: use idx to store index returned by max_bw_index functions

v3: return UINT_MAX in icl_max_bw_index in case no match found

v3: check idx >= ARRAY_SIZE

88d0ecbde9 drm/i915: store the peak bw per QGV point 
In MTL onwards, pcode locks the GV point based on the peak BW
of a QGV point. So store the peak BW of all the QGV points.

v2: use DIV_ROUND_CLOSEST() for the peakBW calculation

39bea0ff0f drm/i915: update the QGV point frequency calculations 
From MTL onwwards, pcode locks the QGV point based on peak BW of
the intended QGV point passed by the driver. So the peak BW
calculation must match the value expected by the pcode. Update
the calculations as per the Bspec.

v2: use DIV_ROUND_* macro for the calculations (Ville)

v3: Use only DIV_ROUN_CLOSEST and remove divisor / 2 again

As is the case with pipe A on gen3 mobile parts, the
PIPECONF gamma mode bit can be set but it has no

PNV seems to be the only slight exception, but generally
the desktop PNV variant looks more like a mobile part so
this is not entirely surprising.

drm_dp_mst_get_edid() to use it.

Note that the old drm_get_edid() ended up calling
drm_connector_update_edid_property(). This responsibility is now
deferred to drivers, which all do it anyway after calling
drm_dp_mst_edid_read() or drm_dp_mst_get_edid().

47d56cadb9 drm/i915: Implement CTM property support for VLV 
VLV has a so called "wide gamut color correction" unit (WGC).
What it is is a 3x3 matrix similar to the later CHV CGM
CSC, with less precisions/range. In fact CHV also has the WGC
but using it there doesn't really make sense when you have the
superior CGM CSC around.

Hook up the necessary stuff to expose the WGC as the CTM
crtc property.

One additional crazy idea that came to mind would be to use
the WGC as an output CSC on CHV for YCbCr output. But it
would be incompatible with the legacy LUT usage. In fact
since the WGC lacks post-offsets we'd probably have to
use the legacy LUT to do that final part of the RGB->YCbCr
conversion. Sounds doable, but perhaps not worth the hassle.
