[PATCH v2 1/2] dt-bindings: tpm-tis-mmio: add compatible string for SynQuacer TPM

From: Ard Biesheuvel
Date: Tue Jan 14 2020 - 09:17:09 EST


Add a compatible string for the SynQuacer TPM to the binding for a
TPM exposed via a memory mapped TIS frame. The MMIO window behaves
slightly differently on this hardware, so it requires its own
identifier.
