Add DTS discription for tas2781 driver code
1. Use subject prefixes matching the subsystem (git log --oneline -- ...).
2. Anyway that's not correct subject. Look at existing commits.
3. Run spell check.
4. Missing full stop.

+description: |
- The TAS2781 is a mono, digital input Class-D audio amplifier
- optimized for efficiently driving high peak power into small
- loudspeakers. Integrated an on-chip DSP supports Texas Instruments
- Smart Amp speaker protection algorithm. The integrated speaker
- voltage and current sense provides for real time
- monitoring of loudspeaker behavior.
+properties:
- compatible:
- enum:
- ti,tas2781
- ti,audev
That's not a correct (real) compatible. Drop.
- description: |
ti,audev will disable the irq of tas2781.
Drop description.
Missing blank line.

I2C address of the device can be between 0x38 to 0x40.
- reset-gpioN:
Nope, use existing property. See gpio-consumer-common
- maxItems: 4
- description: GPIO used to reset the device.
This does not work like that. You did not even test it, right?
- ti,topleft-channel:
- maxItems: 1
- description: I2C Address for each specific device.
No clue what's this. You need to explain in details in description.
- ti,topright-channel:
- maxItems: 1
Ditto and in all other places.
- ti,bottomleft-channel:
- maxItems: 1
- ti,bottomright-channel:
- maxItems: 1
- ti,global-address:
- maxItems: 1
- description: This item is not mandatory. if the device support gloabel mode, this item should be active.
I have no clue what is gloabel mode but the field looks incorrect. Drop or properly describe.
Also wrong line wrapping.
- ti,irq-gpio:
- maxItems: 1
- description: GPIO used to interrupt the device.
No. Use interrupts.

Does not look like you tested the bindings. Please run `make dt_binding_check` (see Documentation/devicetree/bindings/writing-schema.rst for instructions).
