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:
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

2.40.1
The DSS outputs DPI signals via its second video port (VP2). The DPI
output from DSS is 24 bits (RGB888) and is forwarded to an HDMI
transmitter (SIL9022) on the board.
Add pinmux info for DSS DPI output.
Add DT nodes for SIL9022 HDMI transmitter (TX), and the HDMI connector
on the AM625 SK and AM62-LP SK platforms.
Additionally, connect the output of DSS (VP2) with input of the HDMI TX,
and the output of HDMI TX to the input of the HDMI connector.

2.40.1
From: Nishanth Menon <[email protected]>
The DSS outputs DPI signals via its second video port (VP2). The DPI
output from DSS is 24 bits (RGB888) and is forwarded to an HDMI
transmitter (ITE-IT66121) on the BeaglePlay platform. For audio output,
BeaglePlay uses mcasp1.
Add pinmux info for DSS DPI signals.
Further, add support for HDMI audio and video output.

2.40.1
From: Jai Luthra <[email protected]>
Enable audio output over HDMI instead of the 3.5mm jack.
A FET switch (U65) on the EVM muxes serial audio lines coming from McASP
between the codec (tlv320aic3106) and the HDMI bridge (sii9022).
By default it uses the codec, but it can be toggled to use the HDMI
bridge by shorting a (J24) header on the board.

2.40.1
Add Display SubSystem (DSS) DT node for the AM625 SoC.
The DSS supports one each of video pipeline (vid) and video-lite
pipeline (vidl1). It outputs OLDI signals on one video port (VP1) and
DPI signals on another (VP2). The video ports are connected to the
pipelines via 2 identical overlay managers (ovr1 and ovr2).

2.40.1
The Display Data Channel (DDC) transactions between an HDMI transmitter
(SIL9022A in this case) and an HDMI monitor, occur at a maximum of
100KHz. That's the maximum supported frequency within DDC standards.
While the SIL9022A can transact with the core at 400KHz, it needs to
drop the frequency to 100KHz when communicating with the monitor,
otherwise, the i2c controller times out and shows warning like this.
[ 985.773431] omap_i2c 20010000.i2c: controller timed out
That feature, however, has not been enabled in the SIL9022 driver.
Since, dropping the frequency doesn't affect any other devices on the
bus, drop the main-i2c1 frequency from 400KHz to 100KHz.

Rest of the pinmux in the file uses padding of 3. Here you are using
padding of 4. Consistency would be good.
