Subject: [PATCH v2 1/2] dt-bindings: tpm-tis-mmio: add compatible string for SynQuacer TPM
Date: Tue, 14 Jan 2020 15:16:46 +0100
Message-ID: <20200114141647.109347-2-ardb@kernel.org> (raw)
In-Reply-To: <20200114141647.109347-1-ardb@kernel.org>

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.
