* pinctrl: sirf: remove sirfsoc_gpio_set_pull functionArnd Bergmann2012-10-151-35/+0
| | | | | | | | | | | | | | | | | | | | | | | | The prima2 platform advertises needing no mach/gpio.h header file, but its pinctrl driver now has a sirfsoc_gpio_set_pull function that uses constants defined in arch/arm/mach-prima2/include/mach/gpio.h, which fails to build. Fortunately, the sirfsoc_gpio_set_pull is not used anywhere in the kernel, so we can safely remove it. Any out of tree drivers using it will have to be converted to use proper pinctrl functions to do the same. Without this patch, building prima2_defconfig results in: drivers/pinctrl/pinctrl-sirf.c: In function 'sirfsoc_gpio_set_pull': drivers/pinctrl/pinctrl-sirf.c:1331:7: error: 'SIRFSOC_GPIO_PULL_NONE' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1331:7: note: each undeclared identifier is reported only once for each function it appears in drivers/pinctrl/pinctrl-sirf.c:1334:7: error: 'SIRFSOC_GPIO_PULL_UP' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1338:7: error: 'SIRFSOC_GPIO_PULL_DOWN' undeclared (first use in this function) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | In SiRFprimaII, Each GPIO pin can be configured as input or output independently.

* pinctrl: replace list_*() with get_*_count()Viresh Kumar2012-04-181-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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.
