* pinctrl: ab8500: Staticize some symbolsSachin Kamat2013-04-091-2/+3
| | | | | | | | | | | | | These symbols are used only in this file. Silences the following warnings: drivers/pinctrl/pinctrl-ab8500.c:392:28: warning: symbol 'ab8500_alternate_functions' was not declared. Should it be static? drivers/pinctrl/pinctrl-ab8500.c:458:32: warning: symbol 'ab8500_gpio_irq_cluster' was not declared. Should it be static?

* pinctrl/abx500: use direct IRQ definesLinus Walleij2013-02-101-3/+3
| | | | | | | | | Make it harder to do mistakes by introducing the actual defined ABx500 IRQ number into the IRQ cluster definitions. Deduct cluster offset from the GPIO offset to make each cluster coherent. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl/abx500: replace IRQ offsets with table read-in valuesLee Jones2013-02-101-3/+3
| | | | | | | | | | | | | | | | | | The ABx500 GPIO controller used to provide a set of virtual contiguous IRQs for use by sub-devices, but they have been removed after a request from Mainline Maintainers. Now the AB8500 core driver deals with almost all IRQ related issues instead. The ABx500 GPIO driver is now only used to convert between GPIO and IRQ numbers which is actually quite difficult, as the ABx500 GPIO's associated IRQs are clustered together throughout the interrupt number space at irregular intervals. To solve this quandary, we have placed the read-in values into the existing cluster information table to use during conversion.

* pinctrl/abx500: align GPIO cluster boundariesLee Jones2013-02-061-3/+3
| | | | | | | | | | | | | | | | Not quite sure how this ever worked. In ab8500_gpio_to_irq() the GPIO for conversion is passed through as the second argument. If GPIO13, which is a valid GPIO for IRQ functionality, was received; it would be rejected by the following guard: GPIO_IRQ_CLUSTER(5, 12, 0); /* GPIO numbers start from 1 */ if (offset >= cluster->start && offset <= cluster->end) /* Valid GPIO for IRQ use */ Signed-off-by: Lee Jones <lee.jones@linaro.org> [Augmented to account for off-by-one problem] Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl/abx500: add AB8500 sub-driverPatrice Chotard2013-01-301-0/+484
This adds a subdriver for the AB8500 pinctrl portions. As the pin controller (also the ABx500 controllers) is an inherent part of the SoC and will prevent boot if not available, select this from the Ux500 SoC Kconfig.
