TPM dt-bindings cleanup, take three.
The existing devicetrees in arch/arm and arch/arm64 contain a few
violations of the schemas contained herein. E.g. the nodename is
not "tpm@..." but "tpmdev@..." in some cases. I've got patches
lined up to fix these issues and will submit them separately.
Changes v2 -> v3:
* [PATCH 1/4]:
* Drop clock-frequency property from tcg,tpm-tis-i2c.yaml.
It doesn't exist at the peripheral level, only at the
controller level. Document maximum clock frequency for
infineon,slb9635tt and infineon,slb9645tt in textual form
(as was previously done in trivial-devices.yaml).
* Document reset-gpios property as used by:
arch/arm64/boot/dts/freescale/imx8mp-beacon-kit.dts
* [PATCH 2/4]:
* Introduce new schema specifically for google,cr50 (Rob).
Note that I can't use "oneOf" for SPI and I²C properties
because a node with only a "reg" property is a valid SPI
and I²C node and would match both subschemas.
So "anyOf" it is.
* [PATCH 4/4]:
* Use "const" instead of "enum" for singleton compatible string.
