Subject: [PATCH v4 00/12] tnetv107x ssp driver stack
Date: Tue, 26 Oct 2010 16:18:16 -0400 [thread overview]
Message-ID: <1288124308-14999-1-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 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
