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.

This would allow representing a board's static pin configuration +in a single place, rather than splitting it across multiple client device +nodes. The decision to do this or not somewhat rests with the author of +individual board device tree files, and any requirements imposed by the +bindings for the individual client devices in use by that board, i.e. whether +they require certain specific named states for dynamic pin configuration. + +== Pinctrl client devices == + +For each client device individually, every pin state is assigned an integer +ID.

Ventana's pin mux table needed some edits on top of the basic format conversion, since some mux options that were previously marked as reserved are now valid in the new pinctrl driver. Attempting to use the old reserved names will result in a failure. Specifically, groups lpw0, lpw2, lsc1, lsck, and lsda were changed from function rsvd4 to displaya, and group pta was changed from function rsvd2 to hdmi. All boards' pin mux tables needed some edits on top of the based format conversion, since function i2c was split into i2c1 (first general I2C controller) and i2cp (power I2C controller) to better align function definitions with HW blocks. Due to the split of mux tables into pure mux and pull/tristate tables, many entries in the separate Seaboard/Ventana tables could be merged into the common table, since the entries differed only in the portion in one of the tables, not both. Most pin groups allow configuration of mux, tri-state, and pull. However, some don't allow pull configuration, which is instead configured by new groups that only allow pull configuration. This is a reflection of the true HW capabilities, which weren't fully represented by the old pinmux driver. This required adding new pull table entries for those new groups, and setting many other entries' pull configuration to TEGRA_PINCONFIG_DONT_SET.

This change is based on review feedback of the SPEAr pinctrl driver, which had originally copied to Tegra driver structure. This requires that the two drivers have unique names. Update a couple spots in arch/arm/mach-tegra for the name change.

Seaboard actually uses this as an I2C bus mux, and devices are connected to both pingroups. This change statically assigns the I2C2 controller to pingroup PTA, so that on-board devices can be accessed. The DDC pingroup is used for EDID/DDC accesses which are not yet required, given the absence of any Tegra graphics support. I2C muxing will be supported later.
