Subject: [PATCH] dt-bindings: tpm: Add compatible string atmel,attpm20p
Date: Wed, 3 Jan 2024 16:54:14 +0100 [thread overview]
Message-ID: <ea312fdaab76efd1cbcc4ed9fd0e15e5afd1ef88.1704296746.git.lukas@wunner.de> (raw)
Message-ID: <20240103155414.93-qGU4jYFy5x6c0EXMdyw2SO2Vyz5tChxsDLbWzSFE@z> (raw)
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
