i2c: Kill the old driver matching scheme

2008-05-18T18:49:41+00:00

Remove the old driver_name/type scheme for i2c driver matching. Only the
standard aliasing model will be used from now on.

ARM: OMAP: I2C: tps65010 driver converts to gpiolib

2008-04-14T16:57:06+00:00

Make the tps65010 driver use gpiolib to expose its GPIOs.

Note: This patch will get merged via omap tree instead of I2C
as it will cause some board updates. This has been discussed
at on the I2C list:

gpio: rename pca953x symbols

2008-02-06T18:41:15+00:00

This second part of an extension to support more pca953x chips renames the C
and Kconfig symbols.  All affected files were updated by sed, except for a
couple of obvious exceptions.  It also updates the Kconfig helptext.

gpio: rename pca9539 driver

2008-02-06T18:41:15+00:00

First part of an extension to let the pca9539 driver support more chips,
starting with pca9534, pca9535, pca9536, pca9537, and pca9538.

This renames the files and modifies the Makefile.

gpiolib: pca9539 i2c gpio expander support

2008-02-05T17:44:13+00:00

This adds a new-style I2C driver with basic support for the sixteen bit
PCA9539 GPIO expanders.  These chips have multiple registers, push-pull output
drivers, and (not supported in this patch) pin change interrupts.

Board-specific code must provide "pca9539_platform_data" with each chip's
"i2c_board_info".  That provides the GPIO numbers to be used by that chip, and
callbacks for board-specific setup/teardown logic.

Derived from drivers/i2c/chips/pca9539.c (which has no current known users).
This is faster and simpler; it uses 16-bit register access, and cache the
OUTPUT and DIRECTION registers for fast access

gpiolib: pcf857x i2c gpio expander support

2008-02-05T17:44:13+00:00

This is a new-style I2C driver for most common 8 and 16 bit I2C based
"quasi-bidirectional" GPIO expanders: pcf8574 or pcf8575, and several
compatible models (mostly faster, supporting I2C at up to 1 MHz).

The driver exposes the GPIO signals using the platform-neutral GPIO
programming interface, so they are easily accessed by other kernel code.  The
lack of such a flexible kernel API has been a big factor in the proliferation
of board-specific drivers for these chips...  stuff that rarely makes it
upstream since it's so ugly.  This driver will let such boards use standard
calls.

Since it's a new-style driver, these devices must be configured as part of
board-specific init.  That eliminates the need for error-prone manual
configuration of module parameters, and makes compatibility with legacy
drivers (pcf8574.c, pc8575.c) for these chips easier (there's a clear
either/or disjunction).

i2c/tps65010: move header to

2008-01-27T17:14:49+00:00

Move the tps65010 header file from the OMAP arch directory to the
more generic  directory, and remove the spurious
dependency of this driver on OMAP.
