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 Reviewed-by: Jarkko Sakkinen Cc: Tim Harvey Acked-by: Rob Herring --- Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml | 1 + 1 file changed, 1 insertion(+) diff --git a/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml b/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml index c3413b4..6cb2de7 100644 --- a/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml +++ b/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml @@ -20,6 +20,7 @@ properties: compatible: items: - enum: + - atmel,attpm20p - infineon,slb9670 - st,st33htpm-spi - st,st33zp24-spi
