Enable USB3 nodes for the ROC-RK3328-CC board.
The separate power regulator is not added as it is controlled by the
same GPIO line as the existing VBUS regulators, so it is already
enabled. Also there is no port representation to tie the regulator to.

As suggested by Arnd Bergmann, the newly added mmc aliases
should be board specific, so move them from the general dtsi
to the individual boards.

Now that driver support for the RK3328's audio codec, and the plumbing
is defined at the SoC level, we can enable analog audio at the board
level.
Enable analog audio by enabling the codec and the I2S interface
connected and the simple-audio-card that binds them together.

The RK3328-ROC-CC already has HDMI display output enabled. Now that
audio for the HDMI controller is supported, it can be enabled as well.
Enable the simple-audio-card, and the I2S interface the audio is fed
from.

The board has a standard USB A female port connected to the USB OTG
controller's data pins. Set dr_mode in the OTG controller node to
indicate this usage, instead of having the implementation guess.

A test with the command below gives for example this error:

'gpio' is a sort of reserved nodename and should not be used
for pinctrl in combination with 'rockchip,pins', so change
nodes that end with 'gpio' to end with 'pin' or 'pins'.

Current dts files with 'gpio-led' nodes were manually verified.
In order to automate this process leds-gpio.txt
has been converted to yaml. With this conversion a check
for pattern properties was added. A test with the command
below gives a screen full of warnings like:
arch/arm64/boot/dts/rockchip/rk3368-r88.dt.yaml: gpio-leds:
'work' does not match any of the regexes:
'(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'
Fix these errors with help of the following rules:
1: Add nodename in the preferred form.
2: Always add a label that ends with '_led' to prevent conflicts
with other labels such as 'power' and 'mmc'
3: If leds need pinctrl add a label that ends with '_led_pin'
also to prevent conflicts with other labels.
patternProperties:
# The first form is preferred, but fall back to just 'led'
# anywhere in the node name to at least catch some child nodes.

With working GPIO, during init the GPIO state s reset.
This causes the sdmmc regulator to shut down, preventing detection.
Removing and replacing the card will allow it to be detected, but that should not be necessary.
Fix this by setting the regulator on at boot.

Currently the rk3328-roc-cc ethernet is enabled using "snps,force_thresh_dma_mode".
While this works, the performance leaves a lot to be desired.
A previous attempt to improve performance used "snps,txpbl = <0x4>".
This also allowed networking to function, but performance varied between boards.
This patch takes that one step further.
Set txpbl and rxpbl to 0x4.
This can also be accomplished with "snps,pbl =<0x4>" which affects both.
Also set "snps,aal" which forces address aligned DMA mode.

The eMMC 5.x that Libre Computer provide for their boards supports HS200 mode.
The support is already included in the dts for their newest board:
La Frite (AML-S805X-AC)
dts: arch/arm64/boot/dts/amlogic/meson-gxl-s805x-libretech-ac.dts
That same eMMC is supported in the ROC-RK3328-CC:
https://www.loverpi.com/products/libre-computer-board-emmc-5-x-module
This increases the speed of the eMMC significantly.

The rk3328-roc-cc board exhibits tx stability issues with large packets,
as does the rock64 board, which was fixed with this patch
https://patchwork.kernel.org/patch/10178969/
A similar patch was merged for the rk3328-roc-cc here
https://patchwork.kernel.org/patch/10804863/
but it doesn't include the tx/rx_delay tweaks, and I find that they
help with an issue where large transfers would bring the ethernet
link down, causing a link reset regularly.

This patch is a port of the fix from
commit 73e42e186699 ("arm64: dts: rockchip: fix rock64 gmac2io stability
issues")
As per that patch, enabling thresh dma mode force disables checksuming.
This is necessary as tx checksuming does not work with packets larger
than 1498.
The rk3328-roc-cc board exhibits tx stability issues with large packets
similar to rock64's issues. This patch resolves that issue.

In roc-rk3328-cc board, the signal voltage of sdmmc is supplied by the
vcc_sdio regulator, which is a mux between 1.8V and 3.3V, controlled by
a special output only gpio pin labeled "gpiomut_pmuio_iout",
corresponding bit 1 of the syscon GRF_SOC_CON10.
This special pin can now be reference as <&grf_gpio 0>, thanks to the
gpio-syscon driver, which makes writing regulator-gpio possible.
If the signal voltage changes, the io domain needs to change
correspondingly.
To use this feature, the following options are required in kernel config:
- CONFIG_GPIO_SYSCON=y
- CONFIG_POWER_AVS=y
- CONFIG_ROCKCHIP_IODOMAIN=y
