Subject: [PATCH v8 00/11]  tnetv107x ssp drivers
Date: Tue, 18 Jan 2011 14:21:34 -0500	[thread overview]
Message-ID: <1295378505-15221-1-git-send-email-cyril@ti.com> (raw)

TI's sequencer serial port (TI-SSP) is a jack-of-all-trades type of serial port
device.  It has a built-in programmable execution engine that can be programmed
to operate as almost any serial bus (I2C, SPI, EasyScale, and others).

This patch series implements a driver stack that looks like the following:

                             +--------+
                             | eeprom | . . .
                             +--------+
   +-----------+             +--------------+ +---------+
   | regulator | . . .       |   i2c-gpio   | | 1-wire  | . . .
   +-----------+             +--------------+ +---------+
   +----------------------+  +--------------------------------+
   |       ssp-spi        |  |           ssp-gpio             |
   +----------------------+  +--------------------------------+
   +----------------------------------------------------------+
   |                            ssp                           |
   +----------------------------------------------------------+

Changes between v8 and v7 of this series:
  - Reorder commits, removed regulator driver patch (already upstreamed)
  - Renamed static function definitions to keep namespace clean (mfd, gpio)
  - Removed instance pdata in mfd driver

Changes between v7 and v6 of this series:
  - Workaround for iosel2 register not reading back set bits.
  - Update backlight status once probe succeeds.

Changes between v6 and v5 of this series:
  - Changed initcalls to module_init() across all drivers.  This series now
    uses a late_initcall() in the board to delay initialization of gpio and
    regulator dependent devices.

Changes between v5 and v4 of this series:
  - Moved drivers from misc/gpio/spi to mfd
  - Removed implicit init-time iosel setup
  - Minor cleanups in backlight driver

Changes between v3 and v4 of this series:
  - Replaced polled wait for sequence termination with interrupt
  - Improved locking within SSP driver
  - Other minor cleanups

Changes between v2 and v3 of this series:
  - Minor cleanups in Kconfig and Makefile ordering

Changes between v1 and v2 of this series:
  - Replaced open()/close() semantics with dynamic platform_device
    registration on SSP probe.
  - Removed user-land interface to regulator registers
  - More sensible regulator constraints
  - Other minor cleanups
