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, }, ... }; Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2011-07-07gpio/mxc: add missing initialization of basic_mmio_gpio shadow variablesLothar Waßmann
The bgpio_init() function does not initialise the shadow register for the GPIO direction register. Thus, when configuring the first GPIO with gpio_set_direction() all other GPIOs of the same bank will be configured as inputs. Since the bgpio layer cannot know whether the register is readable, the initialisation should be done by the caller of bgpio_init(). Also, the 'data' shadow variable that is used inside basic_mmio_gpio to cache the current value of the GPIO_DR register is initialised from the GPIO_PSR register within bgpio_init(). Thus when setting the output value of a certain GPIO, the other GPIO outputs of the same bank will be set or cleared depending on the pin state of the GPIO inputs during bgpio_init().

2011-06-16gpio/ml-ioh: fix off-by-one for displaying variable i in dev_errAxel Lin
with the "for (; i != 0; i--)" sytax, i-- will be executed after the iteration. thus dev_err shows wrong i value. Switch to "while(--i >= 0)" which is better in readability. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
