58d26c1eab pinctrl: sirf: fix spinlock deadlock in sirfsoc_gpio_set_input
sirfsoc_gpio_set_input() is called in those functions which have
held the spinlock, so delete the duplicated locking.

8dd9766f68 pinctrl: sirf: add missing pins to pinctrl list
We always use pinctrl_request_gpio() to get GPIO, If we don't have these
missing pins in the pin list, gpio_request and related operations will fail
for them.

5130216265 PINCTRL: SiRF: add GPIO and GPIO irq support in CSR SiRFprimaII
In SiRFprimaII, Each GPIO pin can be configured as input or output
independently. If a GPIO is configured as input, it can also be
enabled as an interrupt source (either edge or level triggered).

These pins must be either MUXed as GPIO or other function pads.

d1e90e9e74 pinctrl: replace list_*() with get_*_count()
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.

0d2006bbf0 pinctrl: remove unnecessary max pin number
This patch removes maxpin member in the pin control descriptor
because we don't need this value as we enumerate a pin space
using offset.

3bece55aa5 pinctrl: rename U300 and SIRF pin controllers
For stringent order, rename the pinmux-* pin controllers to
pinctrl-* and also rename the Kconfig symbols and in-kernel
users.
