From 23595de568c1445f5a5cfb3bbad6644578dfc285 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Sat, 13 Jan 2024 18:10:51 +0100 Subject: 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 Reviewed-by: Jarkko Sakkinen Cc: Tim Harvey Acked-by: Rob Herring Signed-off-by: Jarkko Sakkinen --- Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml | 1 + 1 file changed, 1 insertion(+) (limited to 'Documentation') diff --git a/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml b/Documentation/devicetree/bindings/tpm/tcg,tpm_tis-spi.yaml index c3413b47ac3df9..6cb2de7cb5688e 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 -- cgit 1.2.3-korg
