dt-bindings: tpm: Add compatible string atmel,attpm20p
Commit 4f2a348aa365 ("arm64: dts: imx8mm-venice-gw73xx: add TPM device") added a devicetree node for the Trusted Platform Module on certain Gateworks boards. The commit only used the generic "tcg,tpm_tis-spi" compatible string, but public documentation shows that the chip is an ATTPM20P from Atmel (nowadays Microchip): https://trac.gateworks.com/wiki/tpm Add the chip to the supported compatible strings of the TPM TIS SPI schema. For reference, a datasheet is available at: https://ww1.microchip.com/downloads/en/DeviceDoc/ATTPM20P-Trusted-Platform-Module-TPM-2.0-SPI-Interface-Summary-Data-Sheet-DS40002082A.pdf Signed-off-by: Lukas Wunner <lukas@wunner.de> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Cc: Tim Harvey <tharvey@gateworks.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> [ upstream commit: 23595de568c1445f5a5cfb3bbad6644578dfc285 ]
