Subject: [PATCH v5 00/10] drm/vc4: hdmi: Support the 4k @ 60Hz modes
Hi,
Here is a series that enables the higher resolutions on the HDMI0 Controller
found in the BCM2711 (RPi4).
In order to work it needs a few adjustments to config.txt, most notably to
enable the enable_hdmi_4kp60 option.
Let me know what you think,
Maxime
---
Changes from v4:
- Removed the patches already applied
- Added various fixes for the issues that have been discovered on the
downstream tree
Changes from v3:
- Rework the encoder retrieval code that was broken on the RPi3 and older
- Fix a scrambling enabling issue on some display
Changes from v2:
- Gathered the various tags
- Added Cc stable when relevant
- Split out the check to test whether the scrambler is required into
an helper
- Fixed a bug where the scrambler state wouldn't be tracked properly
if it was enabled at boot
Changes from v1:
- Dropped the range accessors
- Drop the mention of force_turbo
- Reordered the SCRAMBLER_CTL register to match the offset
- Removed duplicate HDMI_14_MAX_TMDS_CLK define
- Warn about enable_hdmi_4kp60 only if there's some modes that can't be reached
- Rework the BVB clock computation
Maxime Ripard (10):
drm/vc4: hdmi: Remove the DDC probing for status detection
drm/vc4: hdmi: Fix HPD GPIO detection
drm/vc4: Make vc4_crtc_get_encoder public
drm/vc4: crtc: Add encoder to vc4_crtc_config_pv prototype
drm/vc4: crtc: Rework the encoder retrieval code (again)
drm/vc4: crtc: Add some logging
drm/vc4: Leverage the load tracker on the BCM2711
drm/vc4: hdmi: Raise the maximum clock rate
drm/vc4: hdmi: Enable the scrambler on reconnection
drm/vc4: Increase the core clock based on HVS load
