* pinctrl: Enable "power-source" to be extracted from DT filesIvan T. Ivanov2014-05-282-0/+2
| | | | | | | | | Add "power-source" property to generic options used for DT parsing files. This enables drivers, which use generic pin configurations, to get the value passed to this property.

* pinctrl: sunxi: create irq/pin mapping during initChen-Yu Tsai2014-05-271-2/+3
| | | | | | | | | | | | | | | | | | | | | The irq/pin mapping is used to lookup the pin to mux to the irq function when the irq is enabled. It is created when gpio_to_irq is called. Creating the mapping during init allows us to map the interrupts directly from the device tree. Originally the IRQ to pin mapping was created when gpio_to_irq was called with a GPIO handle. The mapping in turn is used to mux the pin into EINT mode. If the mapping is created during gpio_to_irq, we can't use the interrupts directly, i.e. through the DT with "interrupts = <&pio A 4>". Instead we'd have to use "gpios = <&pio A B>", then pass the gpio through to gpio_to_irq.

* pinctrl/at91: Fix lockup when IRQ on PIOC and PIOD occursAlexander Stein2014-05-271-0/+13
| | | | | | | | | | | | | | | With commit 80cc3732 (pinctrl/at91: convert driver to use gpiolib irqchip) gpiochip_set_chained_irqchip is called for PIOC, PIOD and PIOE. The associated GPIO chip for the IRQ chip is overwritten each time, because they share the same hard IRQ line. Thus if an IRQ occurs on PIOC or PIOD, gpio_irq_handler will only check on PIOE (the assigned GPIO chip) where no event occured. Thus the IRQ will not be cleared, retriggering the ISR. Fix that (like done before) by only set the PIOC GPIO chip to the IRQ chip and walk the list in the irq handler.

* pinctrl: sunxi: Fix multiple registration issueMaxime Ripard2014-05-231-12/+17
| | | | | | | | | | | | | | When the support for the PRCM muxer on the A31 has been added, the global static pinctl_desc definition has been left as is. Unfortunately, this structure is used to register the pinctrl device, and prior to this registration, we set the name and pins field. Since this structure is shared across instances, that means that the latest registered pinctrl device wins in setting the name, pins and pins numbers, which is not really a good thing.

* pinctrl: berlin: add the core pinctrl driver for Marvell Berlin SoCsAntoine Tenart2014-05-236-0/+420
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Marvell Berlin boards have a group based pinmuxing mechanism. This adds the core driver support. We actually do not need any information about the pins here and only have the definition of the groups. Let's take the example of the uart0 pinmuxing on the BG2Q. Balls BK4 and BH6 are muxed to respectively UART0 RX and TX if the group GSM12 is set to mode 0: Group Modes Offset Base Offset LSB Bit Width GSM12 3 sm_base 0x40 0x10 0x2 Ball Group Mode 0 Mode 1 Mode 2 BK4 GSM12 UART0_RX IrDA0_RX GPIO9 BH6 GSM12 UART0_TX IrDA0_TX GPIO10 So in order to configure BK4 -> UART0_TX and BH6 -> UART0_RX, we need to set (sm_base + 0x40 + 0x10) &= ff3fffff. As pin control registers are part of either chip control or system control registers, that deal with a bunch of other functions we rely on a regmap instead of exclusively remapping any resources.

* pinctrl: rockchip: implement PIN_CONFIG_OUTPUT handlingHeiko Stübner2014-04-231-0/+40
| | | | | | | | | In some cases it is nice to be able to simply control a gpio output via the PIN_CONFIG_OUTPUT option without having a driver control it. Thus add support for it to the rockchip pinctrl driver. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl: rockchip: return a complete config in pinconf_getHeiko Stübner2014-04-231-2/+5
| | | | | | | | | | Till now pinconf_get only set the argument value into the config parameter effectively removing the actual config param value. As other pinctrl drivers do, it might be nicer to keep the config param intact. Therefore construct a real pinconfig value from param and arg in pinconf_get Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
