Since commit26c9d152eb("dt-bindings: tpm: Consolidate TCG TIS bindings"), several issues are reported by "make dtbs_check" for ARM devicetrees: The nodename needs to be "tpm@0" rather than "tpmdev@0" and the compatible property needs to contain the chip's name in addition to the generic "tcg,tpm_tis-spi" or "tcg,tpm-tis-i2c": tpmdev@0: $nodename:0: 'tpmdev@0' does not match '^tpm(@[0-9a-f]+)?$' from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm_tis-spi.yaml# tpm@2e: compatible: 'oneOf' conditional failed, one must be fixed: ['tcg,tpm-tis-i2c'] is too short from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm-tis-i2c.yaml# Fix these schema violations. Aspeed Facebook BMCs use an Infineon SLB9670: https://lore.kernel.org/all/ZZSmMJ%2F%2Fl972Qbxu@fedora/ https://lore.kernel.org/all/ZZT4%2Fw2eVzMhtsPx@fedora/ https://lore.kernel.org/all/ZZTS0p1hdAchIbKp@heinlein.vulture-banana.ts.net/ Aspeed Tacoma uses a Nuvoton NPCT75X per commit39d8a73c53("ARM: dts: aspeed: tacoma: Add TPM"). phyGATE-Tauri uses an Infineon SLB9670: https://lore.kernel.org/all/ab45c82485fa272f74adf560cbb58ee60cc42689.camel@phytec.de/ A single schema violation remains in am335x-moxa-uc-2100-common.dtsi because it is unknown which chip is used on the board. The devicetree's author has been asked for clarification but has not responded so far: https://lore.kernel.org/all/20231220090910.GA32182@wunner.de/ Signed-off-by: Lukas Wunner <lukas@wunner.de> Reviewed-by: Patrick Williams <patrick@stwcx.xyz> Reviewed-by: Tao Ren <rentao.bupt@gmail.com> Reviewed-by: Bruno Thomsen <bruno.thomsen@gmail.com>
