-Subject: [PATCH] fsi: Match fsi slaves & engines to available device tree
- nodes
-
-This change populates device tree nodes for scanned FSI slaves and
-engines. If the master populates ->of_node of the FSI master device,
-we'll look for matching slaves, and under those slaves we'll look for
-matching engines.
-
-This means that FSI drivers will have their ->of_node pointer populated
-if there's a corresponding DT node, which they can use for further
-device discover.
-
-Presence of device tree nodes is optional, and only required for
-fsi device drivers that need extra properties, or subordinate devices,
-to be enumerated.

-Subject: [PATCH] hwmon: Add support for MAX31785 intelligent fan controller
-
-Add a basic driver for the MAX31785, focusing on the fan control
-features but ignoring the temperature and voltage monitoring
-features of the device.
-
-This driver supports all fan control modes and tachometer / PWM
-readback where applicable.

-+Kernel driver max31785

-+
-+Description
-+-----------
-+
-+This driver implements support for the Maxim MAX31785 chip.
-+
-+The MAX31785 controls the speeds of up to six fans using six independent
-+PWM outputs. The desired fan speeds (or PWM duty cycles) are written
-+through the I2C interface. The outputs drive "4-wire" fans directly,
-+or can be used to modulate the fan's power terminals using an external
-+pass transistor.
-+
-+Tachometer inputs monitor fan tachometer logic outputs for precise (+/-1%)
-+monitoring and control of fan RPM as well as detection of fan failure.
-+

-From: "Edward A. James" <eajames@us.ibm.com>
-
-This driver provides an atomic communications channel between the OCC on
-the POWER9 processor and a service processor (a BMC). The driver is
-dependent on the FSI SBEIFO driver to get hardware access to the OCC
-SRAM.
-
-The format of the communication is a command followed by a response.
-Since the command and response must be performed atomically, the driver
-will perform this operations asynchronously. In this way, a write
-operation starts the command, and a read will gather the response data
-once it is complete.

-From: "Edward A. James" <eajames@us.ibm.com>
-
-IBM POWER9 processors contain some embedded hardware and software bits
-collectively referred to as the self boot engine (SBE).  One role of
-the SBE is to act as a proxy that provides access to the registers of
-the POWER chip from other (embedded) systems.
-
-The POWER9 chip contains a hardware frontend for communicating with
-the SBE from remote systems called the SBEFIFO.  The SBEFIFO logic
-is contained within an FSI CFAM (see Documentation/fsi) and as such
-the driver implements an FSI bus device.
-
-The SBE expects to communicate using a defined wire protocol; however,
-the driver knows nothing of the protocol and only provides raw access
-to the fifo device to userspace applications wishing to communicate with
-the SBE using the wire protocol.
-
-The SBEFIFO consists of two hardware fifos.  The upstream fifo is used
-by the driver to transfer data to the SBE on the POWER chip, from the
-system hosting the driver.  The downstream fifo is used by the driver to
-transfer data from the SBE on the power chip to the system hosting the
-driver.

-state while other xfers are in progress.
