[PATCH v5 0/6] arm64: ti: k3-am62: Add display support

[PATCH v5 0/6] arm64: ti: k3-am62: Add display support

[Aradhya Bhatia]

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

[PATCH v5 1/6] arm64: dts: ti: k3-am62x-sk-common: Update main-i2c1 frequency

[Aradhya Bhatia]

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.

[PATCH v5 2/6] arm64: dts: ti: k3-am62-main: Add node for DSS

[Aradhya Bhatia]

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).

Also add the DT node for DSS clock divider. This is a fixed-factor-clock
and does not have any register. This comes into effect whenenver OLDI
display is used. The input to this divider is a serial clock used by
OLDI TXes. The divider divides the input clock by 7, and provides the
pixel clock to VP1.

[PATCH v5 3/6] arm64: dts: ti: k3-am62x-sk-common: Add HDMI support

[Aradhya Bhatia]

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.

[PATCH v5 3/6] arm64: dts: ti: k3-am62x-sk-common: Add HDMI support

[Aradhya Bhatia]

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.

[PATCH v5 4/6] arm64: dts: ti: am62x-sk: Add overlay for HDMI audio

[Aradhya Bhatia]

From: Jai Luthra <j-luthra@ti.com>

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.

From: Nishanth Menon <nm@ti.com>

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.

[PATCH v5 5/6] arm64: dts: ti: k3-am625-beagleplay: Add HDMI support

[Aradhya Bhatia]

From: Nishanth Menon <nm@ti.com>

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.

This is a pre-existing issue. Lets not fault Aradhya nor hold back this
series for an issue we caused way back when initially adding AM65 support.

Just to help this along, I've gone and added the fix for these warnings
here[0][1].

I am tempted to plagiarize Lt. Aldo Raine "I want my fixes", but quips
aside, exactly why not picking up patches without fixes is the last
knob I have to force long standing issue resolution :). unfortunate to
need to use it, happy to see it still work.

That said, the patches will have to wait a cycle anyways (cant take
checkpatch warnings with rc1) for the binding to hit 6.6-rc1. In the
meanwhile lets see about getting that fix series merged..

NOTE: This series creates checkpatch warnings against v6.5-rc1 and
complains that it cannot find ti,am625-dss which has been merged in
drm tree for next. This is clean in linux-next for a few weeks now.
Given the number of people who would really like to see it in v6.6-rc1
to keep the display support working in the tree without carried
patches and work on next set of features on display and graphics, and
given the real low risk of this NOT making to linus-master, we are
making an specific exception here for this time around. So, please
keep a watch on drm-next and if for any reason the support is dropped
going to linus's tre in the merge window or before, let this chain
know with appropriate maintainers so that we can take corrective
actions. PS: Thanks Arnd for taking time to give me some private
guidance. Fingers crossed that this will go through smooth.

Thank you!

All being well this means that it will be integrated into the linux-next

the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing

Overlays need to be applied to something. That's done like this:

foo-dtbs := base.dtb k3-am62x-sk-hdmi-audio.dtbo
dtb-y += foo.dtb

Please send a fix for this.
