Subject: [PATCH v3 6/7] dt-bindings: tpm: Add YAML schema for TPM TIS I2C options
Date: Mon, 10 Feb 2020 18:28:37 +0200	[thread overview]
Message-ID: <20200210162838.173903-7-amirmizi6@gmail.com> (raw)
In-Reply-To: <20200210162838.173903-1-amirmizi6@gmail.com>

From: Amir Mizinski <amirmizi6@gmail.com>

Added a YAML schema to support tpm tis i2c realted dt-bindings for the I2c
 PTP based physical layer.

This patch adds the documentation for corresponding device tree bindings of
 I2C based Physical TPM.
Refer to the 'I2C Interface Definition' section in
 'TCG PC Client PlatformTPMProfile(PTP) Specification' publication
 for specification.
