Subject: [PATCH v6 0/7] drivers/i2c: Add FSI-attached I2C master algorithm
Date: Thu, 16 Nov 2017 13:53:45 -0600 [thread overview]
Message-ID: <1510862032-12394-1-git-send-email-eajames@linux.vnet.ibm.com> (raw)
From: "Edward A. James" <eajames@us.ibm.com>
This series adds an algorithm for an I2C master physically located on an FSI
slave device. The I2C master has multiple ports, each of which may be connected
to an I2C slave. Access to the I2C master registers is achieved over FSI bus.
Due to the multi-port nature of the I2C master, the driver instantiates a new
I2C adapter for each port connected to a slave. The connected ports should be
defined in the device tree under the I2C master device.
Changes since v5
- Fix reset functionality and do a reset after every transfer failure
