This patch series adds new pinctrl driver for Samsung SoC's. The driver supports a gpiolib interface as well since Samsung SoC's have a combined pinmux/pinctrl and gpio controller.
The intention of this driver is to replace the existing gpiolib driver and provide drivers pinctrl subsystem interface to configure the pins/mux instead of existing platform callbacks. At this point, the pinmux and pinconfig functionality fully supported and gpiolib is partially supported. Additional work is required to add gpio interrupts and wakeup interrupts support. Hence, this is not ready for merge yet. The first two patches can be looked at in detail. The last three patches are mainly work-in-progress and can be glanced over. The first patch adds a new pinctrl driver for Samsung. It provides interfaces to the pinctrl and gpiolib subsystems. This driver provides a common framework for all Samsung SoC's to enable the pinctrl and gpiolib support. The driver accepts the information about pins, groups, functions and gpio chips using the driver data. The second patch adds information about the pins, groups, functions and gpio chips for the Exynos4210 SoC's. This information is supplied to the Samsung pinctrl driver using driver data. The pinctrl driver registers this information with the pinctrl and gpiolib subsystems. Note: The information about the commonly used groups and functions are added, this list is not exhaustive. The third patch add support for all three pinctrl devices on Exynos4210 SoC. It also adds a minimal common reusable pin maps for boards which are based on Exynos4210 as an example. The pin maps is listed only for the sdhci2 controller for now and this list needs to be expanded. The fourth patch enables pinctrl driver support for Exynos4210 based Origen board as an example of using pinctrl driver. The fifth patch updates the sdhci-s3c driver to use the pinctrl driver interface to setup the pin mux and config settings. This is only intended to be a an example of how to replace the platform callbacks with the pinctrl driver call. This patchset is based on http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git with all patches merged from http://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git [for-next] and tested working of sdhci2 controller on Origen board.
