[ Upstream commit 6ee3ca0ec7fabc63603afdb3485da04164dc8747 ]

McASP AFIFOs are not necessary with UDMA-P/BCDMA as there is buffering
on the DMA IP. Drop these for better audio latency.

arm64: dts: ti: k3-am62x-sk-common: Add HDMI support

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.

arm64: dts: ti: k3-am62x-sk-common: Update main-i2c1 frequency

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.

arm64: dts: ti: Unify pin group node names for make dtbs checks

Prepare for pinctrl-single yaml binding and unify pin group node names.

Let's standardize on pin group node naming ending in -pins. As we don't
necessarily have a SoC specific compatible property for pinctrl-single.
I'd rather not add a pattern match for pins somewhere in the name for all
the users.

Trying to add matches for pins-default will be futile as on the earlier
SoCs we've already seen names like pins-sleep, pins-idle, pins-off and so
on that would need to be matched.

And as the node is a pin group, let's prefer to use naming -pins rather
than -pin as more pins may need to be added to the pin group later on.
