2011-10-04gpio/samsung: correct pin configuration for S5PC100/S5PC110/EXYNOS4Marek Szyprowski1-15/+15
Commit 1b39d5f2cc introduced new common gpio driver for all Samsung GPIO SoCs. The new driver use wrong configuration setup for all gpio pins on S5PC100 and S5PV210 SoCs and external interrupt lines on Exynos4 SoCs. This patch fixes this issue.

Commit 1b39d5f2cc introduced new common gpio driver for all Samsung GPIO SoCs. The new driver doesn't correctly register GPIO interrupts on Samsung Exynos4 SoCs.

2011-09-23gpio: move mpc8xxx/512x gpio driver to drivers/gpioWolfram Sang3-0/+404
Move the driver to the place where it is expected to be nowadays. Also rename its CONFIG-name to match the rest and adapt the defconfigs. Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to the platforms, because this option is per-platform and not per-driver.

The mx3_gpio_irq_handler() is also called on imx6q which has GIC as the primary interrupt controller. As GIC implements the fasteoi flow control, we need to add chained_irq_enter/exit() to mx3_gpio_irq_handler() for signaling EOI, otherwise system will hang whenever there is a gpio irq triggered. v2: use chained_irq_{enter,exit}() Signed-off-by: Shawn Guo <[email protected]> Signed-off-by: Grant Likely <[email protected]>
2011-09-21gpio/samsung: gpio-samsung.c to support Samsung GPIOsKukjin Kim10-2350/+2687
This patch adds support for Samsung GPIOs with one gpio driver and removes old GPIO drivers which are drivers/gpio-s3c24xx.c, gpio-s3c64xx.c, gpio-s5p64x0.c, gpio-s5pc100.c, gpio-s5pv210.c, gpio-exynos4.c, gpio-plat-samsung.c, plat-samsung/gpio-config.c and gpio.c to support each Samsung SoCs before. Because the gpio-samsung.c can replace old Samsung GPIO drivers. Basically, the gpio-samsung.c has been made by their merging and removing duplicated definitions. Note: gpio-samsung.c includes some SoC dependent codes and it will be replaced next time.

2011-09-14drivers/gpio/gpio-generic.c: fix build errorsRussell King1-10/+5
Building a kernel with hotplug disabled results in a link failure: `bgpio_remove' referenced in section `___ksymtab_gpl+bgpio_remove' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o This is because of bgpio_remove() is exported. It is illegal to export symbols which are discarded either at link time or as part of an init/exit section. Fix this by dropping the __devexit attributation from bgpio_remove(). Also drop the __devinit attributation from bgpio_init().

This rewrites the U300 GPIO so as to use gpiolib and struct gpio_chip instead of just generic GPIO, hiding all the platform specifics and passing in GPIO chip variant as platform data at runtime instead of the compiletime kludges.

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 <[email protected]> Signed-off-by: Grant Likely <[email protected]>
