[PATCH v7 1/3] dt-bindings: net: Add ti,cc1352p7

[PATCH v7 1/3] dt-bindings: net: Add ti,cc1352p7

[Ayush Singh]

Add DT bindings for Texas Instruments Simplelink CC1352P7 wireless MCU

BeaglePlay has CC1352P7 co-processor connected to the main AM62 (running
Linux) over UART. In the BeagleConnect Technology, CC1352 is responsible
for handling 6LoWPAN communication with beagleconnect freedom nodes as
well as their discovery.

It is used by gb-beagleplay greybus driver.

[PATCH v7 3/3] dts: ti: k3-am625-beagleplay: Add beaglecc1352

[Ayush Singh]

The BeaglePlay board by BeagleBoard.org has a CC1352P7 co-processor
connected to the main AM62 (running Linux) over UART. In the BeagleConnect
Technology, CC1352 is responsible for handling 6LoWPAN communication with
beagleconnect freedom nodes as well as their discovery.

This mcu is used by gb-beagleplay, a Greybus driver for BeaglePlay.

This does no go here, but to clocks. I wrote how it should be done.
Don't ignore the feedback.

No, really, why do you change correct code into incorrect one? Who asked
you to drop maxItems?

It was suggested to use `clock-names` by Nishanth Menon in the previous 
email, so I thought this was what it meant. I will remove clock-names if 
that's better.

I found that many bindings (`display/ilitek,ili9486.yaml`, 
`iio/dac/adi,ad5758.yaml`) use this pattern instead of `maxItems` for 
`reset-gpios`. So I assumed it was some sort of convention. I will 
change it back to `maxItems`.

Ayush Singh

clock-names could stay, but this description belongs to "clocks:" how I
wrote last time.

Panels are constrained by panel-common.

This I fixed now.

Krzysztof was mentioning that the description should be with clocks.
clock-names would allow for more descriptive dts

maxItems restrict the number of GPIOs to the ones that are actually
needed for the peripheral.
