Several major vendor USB-C->HDMI converters, in particular the DA200,
fail to recover a 5.4 GHz 1 lane signal if the link N is greater than
0x80000.

The link M and N depend on the pixel clock and link clock ratio. With
current code link N exceeds 0x80000 only when link clock >= 540000
kHz. Except for the eDP intermediate link clocks, at least the four
least significant bits are always zero. Just one bit shift right would
be enough to bring even the DP 1.4 810000 kHz link clock under 0x80000
link N. The pixel clock for modes that require a link clock >= 540000
kHz would also have several least significant bits zero. Unless the user
provides a mode with an odd pixel clock value, we can reduce the numbers
to reach the goal, with no loss in precision.

The DP spec even mentions sources making choices that "allow for static
and relatively small Mvid and Nvid values", thus reducing the link M/N
regardless of the sink in question seems justified.

Everything here is based on the work and information gathered by Clint
Taylor <clinton.a.taylor@intel.com>. This is just an iteration to reduce
the parameters regardless of lane count, link rate, or sink.

Geminilake platform sports a native HDMI 2.0 controller, and is
capable of driving pixel-clocks upto 594Mhz. HDMI 2.0 spec
mendates scrambling for these higher clocks, for reduced RF footprint.

This patch checks if the monitor supports scrambling, and if required,
enables it during the modeset.

V2: Addressed review comments from Ville:
 - Do not track scrambling status in DRM layer, track somewhere in
   driver like in intel_crtc_state.
 - Don't talk to monitor at such a low layer, set monitor scrambling
   in intel_enable_ddi() before enabling the port.

V3: Addressed review comments from Jani
 - In comments, function names, use "sink" instead of "monitor",
   so that the implementation could be close to the language of
   HDMI spec.

V4: Addressed review comment from Maarten
 - scrambling -> hdmi_scrambling
 - high_tmds_clock_ratio -> hdmi_high_tmds_clock_ratio

V5: Addressed review comments from Ville and Ander
 - Do not modifiy the crtc_state after compute_config. Move all
   scrambling and tmds_clock_ratio calcutations to compute_config.
 - While setting scrambling for source/sink, do not check the
   conditions again, just go by the crtc_state flags. This will
   simplyfy the condition checks.

V6: Addressed review comments from Ville
 - Do not add IS_GLK check in disable/enable function, instead add it
   in compute_config, while setting state flags.
 - Remove unnecessary paranthesis.
 - Simplyfy handle_sink_scrambling function as suggested.
 - Add readout code for scrambling status in get_ddi_config and add a
   check for the same in pipe_config_compare.

V7: Addressed review comments from Ander/Ville
 - No separate function for source scrambling, make it inline
 - Align the last line of the macro TRANS_DDI_HDMI_SCRAMBLING_MASK
 - Do not add platform check while setting source scrambling
 - Use pipe_config instead of crtc->config to set sink scrambling
 - To readout scrambling status, Compare with SCRAMBLING_MASK
   not any of its bits
 - Remove platform check in intel_pipe_config_compare while checking
   scrambling status

V8: Fixed mege conflict, Addressed review comments from Ander
 - Remove the desciption/comment about scrambling fom the caller, move
   it to the function
 - Move the IS_GLK check into scrambling function
 - Fix alignment

V9: Fixed review comments from Ville, Ander
 - Pass the scrambling state variables as bool input to the sink_scrambling
   function and let the disable call be unconditional.
 - Fix alignments in function calls and debug messages.
 - Add kernel doc for function intel_hdmi_handle_sink_scrambling

If the request->wa_tail is 0 (because it landed exactly on the end of

fill in an illegal value (-8 or 0x001ffff8). As a result, RING_HEAD is
never able to catch up with RING_TAIL and the GPU spins endlessly. If
the ring contains a couple of breadcrumbs, even our hangcheck is unable
to catch the busy-looping as the ACTHD and seqno continually advance.

I noticed that gcc was spilling the CSB to the stack, so rearrange the
code to be more compact. Spilling in this function is slightly more
interesting due to the mmio reads acting as memory barriers and so
end up flushing the stack spills. Still miniscule to having to do at
least the pair of uncached reads :(

There is no need to expose this function as it is called from
one function only. Also move it up to avoid forward declaration.
