Thank you Tao and Patrick for the replies. I've prepared two commits
to fix all violations of the TPM schema on this branch:
https://github.com/l1k/linux/commits/tpm-dt3
The commits are named:
e95bdbc arm64: dts: Fix TPM schema violations
63e5dfd ARM: dts: Fix TPM schema violations
I've now amended the ARM commit to use "infineon,slb9670" for:
arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-bletchley.dts
arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-wedge400.dts
arch/arm/boot/dts/aspeed/ast2600-facebook-netbmc-common.dtsi
I intend to submit the two commits once the TPM schema is applied
either to Jarkko's or Rob's tree:
https://lore.kernel.org/all/20231220160422.GA282877-robh@xxxxxxxxxx/
Thanks,
Lukas
