2011-06-06gpio/mxc: Change gpio-mxc into an upstanding gpio driverShawn Guo
The patch makes necessary changes on gpio-mxc as below to turn it into an upstanding gpio driver. * Add a list to save all mx2 ports references, so that mx2_gpio_irq_handler can walk through all interrupt status registers * Use readl/writel to replace mach-specific accessors __raw_readl/__raw_writel * Change mxc_gpio_init into mxc_gpio_probe function * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to be public at all, and also make some other cleanup on plat-mxc/include/mach/gpio.h at the same time And the patch then migrates mach-imx and mach-mx5 to the updated driver by adding corresponding platform devices.

2010-12-15MXC IOMUX-V3 replace struct pad_desc with bitmapped cookie (step 2)Lothar Waßmann
This patch actually replaces the 'struct pad_desc' with a u64 cookie to facilitate adding platform specific pad_ctrl settings to an existing pad definition. So, instead of: iomux_v3_cfg_t power_key = MX51_PAD_EIM_A27__GPIO_2_21; power_key.pad_ctrl = MX51_GPIO_PAD_CTRL_2; mxc_iomux_v3_setup_pad(&power_key); one can write: mxc_iomux_v3_setup_pad((MX51_PAD_EIM_A27__GPIO_2_21 & ~MUX_PAD_CTRL_MASK) | MX51_GPIO_PAD_CTRL_2); Patch applies to branch 'imx-for-2.6.38' of git://git.pengutronix.de/git/imx/linux-2.6 Signed-Off-By: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2010-12-03iMX51: introduce IMX_GPIO_NRArnaud Patard (Rtp)
Currently, to define a GPIO number, we're using something like : #define EFIKAMX_PCBID0 (2*32 + 16) to define GPIO 3 16. This is not really readable and it's error prone imho (note the 3 vs 2). So, I'm introducing a new macro to define this in a better way. Now, the code sample become : #define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16) v2: - move to gpio.h - add parens & spaces - switch to IMX_GPIO_NR instead of MX51_GPIO_NR Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Cc: Amit Kucheria <amit.kucheria@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Eric Bénard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2010-11-24ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookieLothar Waßmann
The following patch is a first step to convert the 'struct pad_desc' to a bitmapped cookie to facilitate adding platform specific pullup or drive strength definitions to existing pad definitions without need to rewrite the complete pad def. The patch wraps 'struct pad_desc' in an opaque data type and introduces macros to access the individual members. This patch does not constitute any functional change!
