2011-07-15iomux-mx53: add missing 'IOMUX_CONFIG_SION' for some I2C pad definitionsLothar Waßmann
The I2C controller requires the SION bit to be set on SDA and SCL pins. This is missing on some pad definitions for the I2C function. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2011-07-14spi/imx: use soc name in spi device type naming schemeShawn Guo
Software defined version number is not stable enough to be used in device type naming scheme. The patch changes it to use implicit soc name for spi device type definition. In this way, we can easily align the naming scheme with device tree binding, which comes later. It removes fifosize from spi_imx_data and adds devtype there, so that fifosize can be set in an inline function according to devtype. Also, cpu_is_mx can be replaced by inline functions checking devtype.

2011-07-08ARM: mxc: use ARCH_NR_GPIOS to define gpio numberShawn Guo
The patch removes MXC_GPIO_IRQS and instead uses ARCH_NR_GPIOS to define gpio number. This change is need when we change mxc gpio driver to be device tree aware. When migrating the driver to device tree, pdev->id becomes unusable. It requires driver get gpio range from gpio core, which will dynamically allocates number from ARCH_NR_GPIOS to 0. As a bonus point, it removes lines of '#if' and make the code a little bit cleaner. The side effect is the waste of number. But this is not a point when we go single image.

2011-07-08gpio/mxc: get rid of the uses of cpu_is_mx()Shawn Guo
The patch removes all the uses of cpu_is_mx(). Instead, it utilizes platform_device_id to distinguish the different gpio types, IMX1_GPIO on i.mx1, IMX21_GPIO on i.mx21 and i.mx27, IMX31_GPIO on all other i.mx SoCs.

2011-07-07dmaengine: imx-sdma: pass sdma firmware name via platform dataShawn Guo
It is not good to have cpu_name and to_version encoded into sdma firmware name as variables. For example, there are three TOs of imx51 soc, the sdma script never changes since TO1, which means all three TOs of imx51 uses TO1 version of sdma script. But we have to prepare three identical firmwares, sdma-imx51-to1.bin sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel capable of running on all three TOs. The patch removes cpu_name and to_version from sdma platform data, and instead uses fw_name to pass the firmware name, so that we can pass the TO version where it's relevant and skip it where only one firmware exists.

2011-07-07ARM: mxc: clean up imx-dma device registrationShawn Guo
The patch follows the implementation of gpio-mxc device registration to break the concentrated imx-dma device registration into soc specific setup function. Then we can avoid the churn of "#ifdef" and the cpu_is_mx checking on such a long list, which makes no sense, considering more soc supports need to be added and we need to support single image for multiple socs in the long run.

2011-07-07mxc: iomuxv1: Do not use gpio_request when setting the pin as GPIOFabio Estevam
When setting the IOMUX of multiple pins via mxc_gpio_setup_multiple_pins, gpio_request is called and this prevents subsequent calls of gpio_request done by drivers to succeed. Remove gpio_request call from mxc_gpio_setup_multiple_pins function. As gpio_request is removed from mxc_gpio_setup_multiple_pins, there is no need to have mxc_gpio_release_multiple_pins anymore, so remove this function.

2011-06-21net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-06-06gpio/mxc: Change gpio-mxc into an upstanding gpio driverShawn Guo

To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image the ioremap quirk needs a runtime check. While touching this code make the comment more understandable by adding a sentence from the commit log that introduced it (eadefef ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)). As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which #includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros needs to be included before mach/mx27.h and mach/mx31.h.)
