2012-05-13i2c: mxs: add device tree probe supportShawn Guo
Add device tree probe support for i2c-mxs driver. So far, it's only been tested on imx28. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Wolfram Sang <w.sang@pengutronix.de>

2012-05-13mmc: mxs-mmc: add device tree supportShawn Guo
It adds device tree probe support for mxs-mmc driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Chris Ball <cjb@laptop.org>
2012-05-13mmc: mxs-mmc: copy wp_gpio in struct mxs_mmc_hostShawn Guo
Copy wp_gpio from platform_data into struct mxs_mmc_host, so that the use of platform_data can be limited in probe function, which will ease the device tree probe. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Marek Vasut <marex@denx.de> Acked-by: Chris Ball <cjb@laptop.org>
2012-05-13mmc: mxs-mmc: have dma_channel than dma_res in mxs_mmc_hostShawn Guo
It replaces dma_res with dma_channel in struct mxs_mmc_host, so that the device tree support will be a little easier, since dma channel can not be retrieved from "struct resource *dma_res".

2012-05-13mmc: mxs-mmc: move header from mach into linux folderShawn Guo
Rename arch/arm/mach-mxs/include/mach/mmc.h to include/linux/mmc/mxs-mmc.h, so that mxs-mmc driver becomes <mach/*> inclusion free. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Marek Vasut <marex@denx.de> Acked-by: Chris Ball <cjb@laptop.org>
2012-05-13mmc: mxs-mmc: get rid of the use of cpu_is_xxxShawn Guo
The register HW_SSP_VERSION is broken for ssp version detection, as the address of the register is different between imx23 and imx28. Let's use platform_device_id to detect the device, so that the use of cpu_is_xxx can be removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Chris Ball <cjb@laptop.org>

2012-05-12gpio/mxs: get rid of the use of cpu_is_xxxShawn Guo
It removes the use of cpu_is_xxx from gpio-mxs driver and instead use platform_device_id to identify the device. Accordingly, mxs platform code is changed to register gpio device with different names, and the registeration are done in soc specific initialization functions now, so postcore_initcall(mxs_add_mxs_gpio) gets removed.

2012-05-08ARM: mxs: enable pinctrl dummy statesShawn Guo
The mxs pinctrl driver will only support DT probe. That said, the mxs device drivers can only get pinctrl state from pinctrl subsystem when the drivers get probed from device tree. Before converting the whole mxs platform support over to device tree, we need to enable pinctrl dummy states for those non-DT board files to ensure the pinctrl API adopted by mxs device drivers will work for both DT and non-DT probe. Instead of calling pinctrl_provide_dummies() directly in every board file, the patch introduces soc specific calls mx23_soc_init() and mx28_soc_init() for boards' .init_machine hook to invoke, so that any soc specific setup for non-DT boot only can be added there.
