2014-10-02pinctrl: specify bindings for pins and groupspinctrl-v3.18-1Linus Walleij
Pin configurations can be per-pin or per-group. Make sure that the per-group case is covered by the bindings. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2014-09-30pinctrl: nomadik: improve GPIO debug printsLinus Walleij
The debugfs file would only define if the line was "pulled" and not which direction (pull up or pull down). Improve this by taking two print paths depending on whether the pin is set as input or output and use the data register directly to figure out whether the pin is set for pull up or pull down.

2014-09-26pinctrl: qcom: use restart_notifier mechanism for ps_holdJosh Cartwright
By converting to the restart_notifier mechanism for restart, we allow for other mechanisms, like the watchdog, to be used for restart in the case where PS_HOLD has failed to reset the chip. Since this mechanism may be one of several mechanisms registered, change the post-ps_hold write timeout to be a more reasonable 1 second instead of 10 seconds. Choose priority 128, as according to documentation, this mechanism "is sufficient to restart the entire system".

2014-09-23pinctrl: at91: Fix error handling while doing gpiochio_irqchip_addPramod Gurav
This patch removes a call to panic function when gpiochio_irqchip_add fails and just returns the error to the calling function. Same return value is used to handle the error case and adds a lable to release resources on error. The error message has been improved to indicate failure to add irqchip to gpiochip. This also changes first argument to function at91_gpio_of_irq_setup from struct device_node to struct platform_device. Because The device_node argument was anyway not being used. Passed pdev so that on failure dev_err can use &pdev->dev and log can be associated with proper device.

2014-09-23pinctrl: imx: detect uninitialized pinsStefan Agner
The pinctrl driver initialized the register offsets for the pins with 0. On Vybrid an offset of 0 is a valid offset for the pinctrl mux register. So far, this was solved using the ZERO_OFFSET_VALID flag which allowed offsets of 0. However, this does not allow to verify whether a pins struct imx_pmx_func was initialized or not. Use signed offset values for register offsets and initialize those with -1 in order to detect uninitialized offset values reliable.

2014-09-05pinctrl: at91: add drive strength configurationMarek Roszko
The SAMA5 and SAM9x5 series both have drive strength options for the PIOs. This patch adds the ability to set one of three hardware options for drive strengths of low, medium or high for the each pin. The actual current output of the chip based on the setting is defined in the datasheets and varies per pins separate from banks and with supply voltage. This patch adds three new dt-bindings that allow setting the strength when configuring pins. By default, no change will be made to the drive strength of a pin from its reset value. Due to the difference between the register addresses of the SAMA5 and SAM9x5 series, a new sama5d3-pinctrl id was added.

2014-09-04pinctrl: qcom: Make the target processor value configurableGeorgi Djakov
Currently the value used to specify that interrupts from the gpio should be routed to the application processor is hardcoded for all Qualcomm SoCs. But the new APQ8084 SoC uses a different value. To resolve this, we make this value configurable for each SoC. For all existing SoCs we continue to use the current value, and only for APQ8084 we use the new value.

This patchset adds pinctrl support for the Qualcomm APQ8084 platform. This set of patches adds pinctrl support for the Qualcomm APQ8084 platform. The first patch adds the pin definitions. The second patch contains the devicetree binding documentation. The third patch adds the DT node. The last patch makes the INTR_TARGET_PROC_APPS value configurable and defines it for each existing SoC. Tested on IFC6540 board. Changes since v3: - Fixed the sdc valid pin values in the binding documentation - sdc2 instead of sdc3. (suggested by Bjorn Andersson) Changes since v2: - Fixed some incorrect bits and offsets. (suggested by Bjorn Andersson) - Updated binding documentation to follow the format of msm8960. (suggested by Bjorn Andersson) - Added fourth patch, which removes the hardcoded INTR_TARGET_PROC_APPS value and makes it configurable. Also we keep the current value for existing SoCs.

commit 2243a87d90b42eb38bc281957df3e57c712b5e56 "pinctrl: avoid duplicated calling enable_pinmux_setting for a pin" removed the .disable callback from the struct pinmux_ops, making the .enable() callback the only remaining callback. However .enable() is a bad name as it seems to imply that a muxing can also be disabled.
