The driver has mux and config support while the gpio is still not supported. For select input setting, the driver will handle it internally and do not need user to take care of it. The pinctrl-imx core driver will parse the dts file and dynamically create the pinmux functions and groups. Each IMX SoC pinctrl driver should register pins with a pin register map including mux register and config register and select input map to core for proper operations.

Add a interface pinctrl_provide_dummies for platform to indicate whether it needs use pinctrl dummy state. ChangeLog v3->v4: * remove dummy gpio support in pinctrl subsystem. Let gpio driver decide whether it wants to use pinctrl gpio mux function. ChangeLog v2->v3: * Also changed the missed pinctrl gpio APIs in v1. ChangeLog v1->v2: * Based on sascha's suggestion, drop using kconfig since it will hide pinctrl errors on all other boards. See: https://lkml.org/lkml/2012/4/18/282 It seemed both Linus and Stephen agreed with this way, so i'm ok with it too. * Add dummy gpio support. pinctrl gpio in the same situation as state. * Patch name changed.

There are a few places in the api where the code simply returns -EINVAL when it finds an error. An example is pinmux_map_to_setting() which now reports an error if we try to match a group with a function that it does not support. The reporting of errors in pinconf_check_ops and pinmux_check_ops now has the same style and is located inside the according functions and not the calling code. When the map is found in the DT but the default state can not be selected we get an error to know that the code at least tried. The patch also removes a stray word from one comment and a "->" from another for the sake of consistency. Finally we replace a few pr_err/debug() calls with dev_err/dbg(). Thanks go to Stephen Warren for reviewing the patch and enhancing the reporting inside pinmux_map_to_setting().

pinmux_map_to_setting() uses setting->data.mux.func/group to store the return code of pinmux_func_name_to_selector/pinctrl_get_group_selector(). However, struct pinctrl_setting_mux defines these elements as unsigned, resulting in all error codes getting lost. The conditionals following the assignments will always evaluate to false thus breaking the error paths. This bug can be triggered by loading a pinmux group map from the devicetree with an invalid function/group string.

If drivers try to obtain pinctrl handles for a pin controller that has not yet registered to the subsystem, we need to be able to back out and retry with deferred probing. So let's return -EPROBE_DEFER whenever this location fails. Also downgrade the errors to info, maybe we will even set them to debug once the deferred probing is commonplace.

Most of the SoC drivers implement list_groups() and list_functions() routines for pinctrl and pinmux. These routines continue returning zero until the selector argument is greater than total count of available groups or functions. This patch replaces these list_*() routines with get_*_count() routines, which returns the number of available selection for SoC driver. pinctrl layer will use this value to check the range it can choose. This patch fixes all user drivers for this change. There are other routines in user drivers, which have checks to check validity of selector passed to them. It is also no more required and hence removed. Documentation updated as well.
