[PATCH v4 00/12] tnetv107x ssp driver stack

[Cyril Chemparathy]

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 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
