Subject: [PATCH v9 7/8] tpm: Add YAML schema for TPM TIS I2C options
Date: Tue, 26 May 2020 17:16:57 +0300	[thread overview]
Message-ID: <20200526141658.157801-8-amirmizi6@gmail.com> (raw)
In-Reply-To: <20200526141658.157801-1-amirmizi6@gmail.com>

From: Amir Mizinski <amirmizi6@gmail.com>

Added a YAML schema to support tpm tis i2c related 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.
