Subject: [PATCH v2 0/5] add tpm i2c ptp driver
Date: Mon, 2 Dec 2019 15:33:27 +0200 [thread overview]
Message-ID: <20191202133332.178110-1-amirmizi6@gmail.com> (raw)
From: Amir Mizinski <amirmizi6@gmail.com>
This patch set adds support for TPM devices that implement the I2C.
Interface defined by TCG PTP specification:
https://trustedcomputinggroup.org/wp-content/uploads/TCG_PC_Client_Platform_TPM_Profile_PTP_2.0_r1.03_v22.pdf
The driver was tested on Raspberry-Pie 3, using Nuvoton NPCT75X TPM.
Interupts are not implemented yet, preparing it for the next patch.
This patch is based on initial work by oshri Alkoby, Alexander Steffen and Christophe Ricard
