Peter Korsgaard 752ad5e82d mcp23s08: add i2c support
Add i2c bindings for the mcp230xx devices. This is quite a lot simpler
than the spi one as there's no funky sub addressing done (one struct
i2c_client per struct gpio_chip).

The mcp23s08_platform_data structure is reused for i2c, even though
only a single mcp23s08_chip_info structure is needed.

To use, simply fill out a platform_data structure and pass it in
i2c_board_info, E.G.:

static const struct mcp23s08_platform_data mcp23017_data = {
	.chip[0] = {
		.pullups = 0x00ff,
	},
	.base = 240,
};

static struct i2c_board_info __initdata i2c_devs[] = {
	{ I2C_BOARD_INFO("mcp23017", 0x20),
	  .platform_data = &smartview_mcp23017_data, },
	...

Andres Salomon 1b912c1bca drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO functionality
This adds (well, re-adds actually) handling for events/IRQs through cs5535
GPIOs.  In the wild and wooly world of CS5535, setup_event() is for
assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the
pair to trigger IRQs.

These should really only be used in highly platform-specific drivers (such
as OLPC's DCON driver).  Sadly, because set_irq() uses MSRs, this causes
the driver to become X86-specific.

Miguel Gaio ead6db0843 gpio: add support for 74x164 serial-in/parallel-out 8-bit shift register
Add support for generic 74x164 serial-in/parallel-out 8-bits shift
register.  This driver can be used as a GPIO output expander.

Anton Vorontsov aeec56e331 gpio: add driver for basic memory-mapped GPIO controllers
The basic GPIO controllers may be found in various on-board FPGA and ASIC
solutions that are used to control board's switches, LEDs, chip-selects,
Ethernet/USB PHY power, etc.

These controllers may not provide any means of pin setup
(in/out/open drain).

The driver supports:
- 8/16/32/64 bits registers;
- GPIO controllers with clear/set registers;
- GPIO controllers with a single "data" register;
- Big endian bits/GPIOs ordering (mostly used on PowerPC).
