Subject: [PATCH v4 00/12] drm/vc4: hdmi: Support the 4k @ 60Hz modes
Date: Fri, 7 May 2021 17:05:03 +0200 [thread overview]
Message-ID: <20210507150515.257424-1-maxime@cerno.tech> (raw)
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 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 (12):
drm/vc4: txp: Properly set the possible_crtcs mask
drm/vc4: crtc: Skip the TXP
drm/vc4: crtc: Pass the drm_atomic_state to config_pv
drm/vc4: crtc: Fix vc4_get_crtc_encoder logic
drm/vc4: crtc: Lookup the encoder from the register at boot
drm/vc4: hdmi: Prevent clock unbalance
drm/vc4: hvs: Make the HVS bind first
drm/vc4: hdmi: Properly compute the BVB clock rate
drm/vc4: hdmi: Check and warn if we can't reach 4kp60 frequencies
drm/vc4: hdmi: Enable the scrambler
drm/vc4: hdmi: Add a workqueue to set scrambling
drm/vc4: hdmi: Raise the maximum clock rate
