Universal Serial Interface (USI) supports three types of serial
interface such as UART, SPI and I2C. Each protocol works independently.
USI can be configured to work as one of these protocols. Define all the
USI nodes from the PERIC blocks (USI0-14), in all their possible
configurations. These blocks have the TX/RX FIFO depth of 64 bytes.

This should fit within 81 characters, which is pretty close to 80, so if
there is going to be any resend/new version, please join the lines.

I wonder why we use four cells in GIC...

Please reverse two lines, first pinctrl-0 then pinctrl-names. I know we
did not follow this convention till now, but at least new code can be
correct. Also clocks should be before pinctrl, so we keep some sort of
alphabetical order.

It is anyway too late in the cycle for me to pick it up, so no need to
hurry with resend.

Best regards,

Due to the ppi-partitions defined in the gic for the pmu-(0-2) devices.

I'd like to respin this patch. Any preference on coding style for
#address-cells and #size-cells? I guess they shall be above ranges
property if present.

Ok.

Ok.

I guess the order shall be:

1. compatible
2. reg
3. #address-cells (if applicable)
   #size-cells (if applicable)
4. ranges (if applicable)
5. Standard/common properties ordered alphabetically (ex. clocks,
   interrupts, pinctrl)
6. vendor-specific properties
7. status (if applicable)

Please let me know if you have other preference. Thanks!

No, ranges should be just after reg, because it encodes often the same
or similar information (see also DTS Coding Style). I don't have
guideline, can be anywhere before vendor properties.

Rest looks fine, thanks.
