Subject: [PATCH v7 0/2] dt-bindings: cros-ec: Update for fingerprint devices

This patch series introduces a DT binding for chromeos fingerprint
devices. The first patch tightens up the existing cros-ec binding and
the second patch introduces the fingerprint binding. As there aren't any
driver patches this can go directly through the chrome platform
tree or the dt-binding tree or the mfd tree. I sent it to the binding
maintainers in hopes it can go there directly but it doesn't really
matter.

Changes from v6 (https://lore.kernel.org/r/20220614195144.2794796-1-swboyd@chromium.org):
 * Put back into the same cros-ec binding file again
 * Gave up trying to make it use additionalProperties: false and added a
   comment instead
 * Made symmetric for the spi and rpmsg case

Changes from v5 (https://lore.kernel.org/r/20220512013921.164637-1-swboyd@chromium.org):
 * Split out to different binding file again, while using 'select'
 * Fixed examples to have required interrupts property for cros-ec-spi

Changes from v4 (https://lore.kernel.org/r/20220321191100.1993-1-swboyd@chromium.org):
 * Drop last patch that implemented driver logic
 * Drop second to last patch because it's not really needed until
   compatible is used.
 * Rolled cros-ec-spi into cros-ec-fp compatible to get all the pieces

Changes from v3 (https://lore.kernel.org/r/20220318015451.2869388-1-swboyd@chromium.org):
 * Drop spi_device_id because it isn't used
 * Dropped struct members for gpios
 * Picked up tags

Changes from v2 (https://lore.kernel.org/r/20220317005814.2496302-1-swboyd@chromium.org):
 * Dropped cros-ec spi dt properties that aren't of use right now
 * Picked up tags

Changes from v1 (https://lore.kernel.org/r/20220314232214.4183078-1-swboyd@chromium.org):
 * Properly do the boot sequence
 * Add a message that we're booting and delaying a while
 * Fix typo in commit text
 * Change binding to not spell out reset-gpios and indicate that boot0
   is about asserting boot mode
 * Split device id to different patch as it's a different topic from
   booting
