| | | | | | | | | | This driver allows clk_get() failure, and still work without it.

* pinctrl: spear: Make get_gpio_pingroup return NULL when no gpio_pingroup foundAxel Lin2012-11-151-3/+3
| | | | | | | | | | | Currently get_gpio_pingroup() may return NULL or ERR_PTR(-EINVAL) when no gpio_pingroup found. The caller in gpio_request_endisable() only checks if the return value is NULL. Return ERR_PTR(-EINVAL) for get_gpio_pingroup() causes problem and seems not necessary.

* pinctrl: SPEAr: Add SoC specific gpio configuration routinesShiraz Hashim2012-11-113-14/+53
| | | | | | | | | | | | | | | | | Different SPEAr SoCs have different approach to configure pins as gpios. Some configure a group of gpios with single register bit and others have one bit per gpio pin. Only earlier one is implemented till now, this patch adds support for later one. Here we add callbacks to SoC specific code to configure gpios in gpio_request_enable(). That will do additional SoC specific configuration to enable gpio pins. We also implement this callback for SPEAr1340 in this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are some unnecessary criss-cross dependencies between the PRCMU driver in MFD and a lot of other drivers, mainly because other drivers need to poke around in the PRCM register range. In cases like this there are actually just a few select registers that the pinctrl driver need to read/modify/write, and it turns out that no other driver is actually using these registers, so there are no concurrency issues whatsoever. So: don't let the location of the register range complicate things, just poke into these registers directly and skip a layer of indirection. Take this opportunity to add kerneldoc to the pinctrl state container.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With DB8500 the number of GPIO chips = number GPIO bank = number of GPIO ranges. With DB8540, a new GPIO range configuration is used, some GPIO banks can have several GPIO ranges. For example, DB8540 GPIO bank0 (GPIO0 to GPIO32) have 2 GPIO ranges: - GPIO0 to GPIO17 : routed - GPIO18 to GPIO21 : hole - GPIO22 to GPIO28 : routed - GPIO29 to GPIO32 : hole Previously, during nmk_pinctrl_probe(), all GPIO ranges were parsed, as GPIO ranges are larger than the number of GPIO chips, a warning occurs.

So separate the concerns of gpiolib.c and gpiolib-of.c and have the latter call the former as back-end. This is necessary also when going forward with other device descriptions such as ACPI. This is done by: - Adding a return code to gpiochip_add_pin_range() so we can reliably check whether this succeeds. - Get rid of the custom of_pinctrl_add_gpio_range() from pinctrl. Instead create of_pinctrl_get() to just retrive the pin controller per se from an OF node. This composite function was just begging to be deleted, it was way to purpose-specific. - Use pinctrl_dev_get_name() to get the name of the retrieved pin controller and use that to call back into the generic gpiochip_add_pin_range(). Now the pin range is only allocated and tied to a pin controller from the core implementation in gpiolib.c. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
