Hi all,
The patch series adds DT nodes for Display SubSystem (DSS) and other
peripherals required to enable the HDMI audio and video on the AM625 SK,
AM62-LP SK, as well as the AM625 based Beagle-Play platforms. An HDMI
monitor can be connected to the boards for the audio/video outputs.
The series adding the compatible and basic driver support[0] is in the
drm-misc-next and linux-next queues and is expected to be in the
mainline by v6.6-rc1. Patch 5/6 also requires Nishanth Menon's patch[1]
that introduces debounce select mux macros. This patch too is not in
v6.5-rc1 but has been picked up in ti-next[2] and hence, is present in
linux-next.
Patches 4 and 5 have been picked up from TI's vendor tree[3] based off
linux-kernel v6.1.
Regards
Aradhya
Change Log:
V4 -> V5:
- Cosmetic changes as suggested by Jayesh.
- Fixed the mis-represented DSS VP1 clock, and added a
fixed-factor-clock.
V3 -> V4:
- Added "Fixes" tag for patch 1/6.
- Rebased to linux-next.
- Enabled display at board level and disabled at SoC level.
- Dropped OLDI pinmux configuration as OLDI output comes directly from
the SoC and muxing is not required.
- Squashed DSS pinmux patches into their platform specific HDMI
support patches, because it did not make sense to have only one set
of pinmux config separated in a patch.
V2 -> V3:
- Updated the compatible from "ti,am65x-dss" to "ti,am625-dss".
- Peripheral nodes like HDMI TX, HDMI connector are now added to
k3-am62x-sk-common.dtsi instead of k3-am625-sk.dts, in order to
support AM62-LP SK-EVM as well.
- Dropped the HDMI master clock node as it is not connected on the
EVM, and should not have been added in the first place.
- Re-worded and Re-ordered commits.
- Dropped Rahul Ravikumar's R-bs because of the changes.
- Added AM625 based Beagle-Play for HDMI support.
- Added HDMI audio support as well.
V1 -> V2:
- Removed repetitive data in dss_ports
