Subject: [PATCH v3 0/4] dt-bindings: tpm: Clean all the things
Date: Sun, 17 Dec 2023 11:13:30 +0100	[thread overview]
Message-ID: <cover.1702806810.git.lukas@wunner.de> (raw)

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.
