Subject: [PATCH v2 00/13] drm: Add generic helpers for HDMI scrambling
Date: Thu, 18 Nov 2021 11:38:01 +0100 [thread overview]
Message-ID: <20211118103814.524670-1-maxime@cerno.tech> (raw)
Hi,
This is a follow-up of the work to support the interactions between the hotplug
and the scrambling support for vc4:
https://lore.kernel.org/dri-devel/20210507150515.257424-11-maxime@cerno.tech/
https://lore.kernel.org/dri-devel/20211025152903.1088803-10-maxime@cerno.tech/
Ville feedback was that the same discussion happened some time ago for i915,
and resulted in a function to do an full disable/enable cycle on reconnection
to avoid breaking the HDMI 2.0 spec.
This series improves the current scrambling support by adding generic helpers
for usual scrambling-related operations, and builds upon them to provide a
generic alternative to intel_hdmi_reset_link.
Let me know what you think,
Maxime
Changes from v1:
- Dropped the 340MHz define
- Make drm_mode_hdmi_requires_scrambling use the bpc
- Make more drm_display_mode const in vc4
- Dropped the tegra conversion
- Added more comments
Maxime Ripard (13):
drm/connector: Add helper to check if a mode requires scrambling
drm/atomic: Add HDMI scrambler state helper
drm/atomic: Add HDMI reset link helper
drm/scdc: Document hotplug gotchas
drm/vc4: hdmi: Constify drm_display_mode
drm/vc4: hdmi: Remove unused argument in vc4_hdmi_supports_scrambling
drm/vc4: hdmi: Remove mutex in detect
drm/vc4: hdmi: Remove HDMI flag from encoder
drm/vc4: hdmi: Simplify the hotplug handling
drm/vc4: hdmi: Simplify the connector state retrieval
drm/vc4: hdmi: Switch to detect_ctx
drm/vc4: hdmi: Leverage new SCDC atomic_check
drm/vc4: hdmi: Reset link on hotplug
