Hi,

Rebased on next-20220714

Merging
=======
1. The first five patches (panel, eeprom, iio, misc and net) are independent
   and could be taken as is.
2. The last SPI patch depends on all previous five, so:
   a. either everything goes through one tree (e.g. DT bindings),
   b. or SPI patch waits one cycle till dependencies get to rcX.

Preference is (2a) - everything through one tree because I plan to include
spi-peripheral-props.yaml in several SPI client bindings (continuation of [1]).

However IIO and SPI patch might not apply cleanly on DT bindings tree, as I
based it on linux-next. I can rebase if such merging is preferred.

Description
===========
The spi-cpha and spi-cpol properties are device specific and should be
accepted only if device really needs them.  Inspired by [1].

Not great duplicating the type and description everywhere.

We can move the definition back to spi-controller.yaml, so then that 
does type checking of the property, but not presence/absence checks.

This whole patch can be dropped which will make merging easier.

This too should not be needed.

If I understand correctly, all client devices (which do no reference
spi-controller) will need to explicitly mention CPHA/CPOL. Good idea.
