Entries are needed in the spidev ID list to configure configure it from a
device tree. Add entries for the following devices:
- "fsl,mk20fn1m0vmd12" : a cortex m4 based chip
- "exar,xra1403" : a GPIO expander

This compatible is in uppercase which is not the normal style for DT
bindings at all. I'd also guess that this is a binding for a specific
application running on this device rather than the chip itself.

Looks like a suitable target for a drivers/gpio/ driver.

Good idea, however we have to measure impact of this change on the project.

Entries are needed in the spidev ID list to configure configure it from a
device tree. Add entry for the following device:
- "ge,achc" : GE Healthcare USB Management Controller
The USB Management Controller does not expose USB to the host, but acts as
an offload engine, communicating with specific USB based data acquisition
devices which are connected to it, extracting the required data and
providing it to the host via other methods. SPI is used as an out-of-band
configuration channel.

Please use subject lines matching the style for the subsystem. This
