Hi,=0D

Here is a series that enables the higher resolutions on the HDMI0 Controlle=
r=0D
found in the BCM2711 (RPi4).=0D
=0D
In order to work it needs a few adjustments to config.txt, most notably to=
=0D
enable the enable_hdmi_4kp60 option.=0D
=0D
Let me know what you think,=0D

Changes from v3:=0D
  - Rework the encoder retrieval code that was broken on the RPi3 and older=
=0D
  - Fix a scrambling enabling issue on some display=0D

Changes from v2:=0D
  - Gathered the various tags=0D
  - Added Cc stable when relevant=0D
  - Split out the check to test whether the scrambler is required into=0D
    an helper=0D
  - Fixed a bug where the scrambler state wouldn't be tracked properly=0D
    if it was enabled at boot=0D
=0D
Changes from v1:=0D
  - Dropped the range accessors=0D
  - Drop the mention of force_turbo=0D
  - Reordered the SCRAMBLER_CTL register to match the offset=0D
  - Removed duplicate HDMI_14_MAX_TMDS_CLK define=0D
  - Warn about enable_hdmi_4kp60 only if there's some modes that can't be r=
eached=0D
  - Rework the BVB clock computation=0D
