* pinctrl: qcom: Make the target processor value configurableGeorgi Djakov2014-09-047-3/+14
| | | | | | | | | | | | | 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.

* pinctrl: qcom: Add APQ8084 pinctrl supportGeorgi Djakov2014-09-043-0/+1252
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (suggested by Bjorn Andersson) Changes since v1: - Updated the total number of pins (suggested by Bjorn Andersson) - Added the missing pin info (provided by Andy Gross) - Updated groups and functions to be consistent with other pinctrls. (suggested by Andy Gross) - Removed unused functions, qdss and test pins. (suggested by Andy Gross) - Updated the documentation with the possible functions.

* pinctrl: clean up after enable refactoringLinus Walleij2014-09-0432-99/+105
| | | | | | | | | | | | | | | | | 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. Rename the callback to .set_mux() and also take this opportunity to clean out any remaining mentions of .disable() from the documentation.

There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable.

There are several new boards added, and a couple of SoCs.

This resulted in large, bogus gpio numbers for the new sun6i-a31-r pinctrl devices. This patch makes the driver number the gpios ranges starting from an offset of 0, by subtracting the pin_base number from the pin number. This also makes the system-wide gpio number match the pin number. Tested on sun8i with sysfs exported gpios. This patch also changes the GPIO bindings for R_PIO: gpios = <&r_pio B N flag>; Where B originally was the pinbank label (L or M) counted from A, with this patch it becomes (L or M) counted from its pinbank base (L). Thus gpios = <&r_pio 10 11 0>; /* PL11 */ becomes gpios = <&r_pio 0 11 0>; /* PL11 */ IMO this is correct, as the binding shows the bank offset and pin offset within the bank for the GPIO controller. But I'm worried it might be a bit confusing.

| * | | pinctrl: samsung: Allow grouping multiple pinmux/pinconf nodesTomasz Figa2014-07-112-252/+362
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of remaining limitations of current pinctrl-samsung driver was the inability to parse multiple pinmux/pinconf group nodes grouped inside a single device tree node. It made defining groups of pins for single purpose, but with different parameters very inconvenient. This patch implements Tegra-like support for grouping multiple pinctrl groups inside one device tree node, by completely changing the way pin groups and functions are parsed from device tree. The code creating pinctrl maps from DT nodes has been borrowed from pinctrl-tegra, while the initial creation of groups and functions has been completely rewritten with following assumptions: - each group consists of just one pin and does not depend on data from device tree, - each function is represented by a device tree child node of the pin controller, which in turn can contain multiple child nodes for pins that need to have different configuration values. Device Tree bindings are fully backwards compatible. New functionality can be used by defining a new pinctrl group consisting of several child nodes, as on following example: sd4_bus8: sd4-bus-width8 { part-1 { samsung,pins = "gpk0-3", "gpk0-4", "gpk0-5", "gpk0-6"; samsung,pin-function = <3>; samsung,pin-pud = <3>; samsung,pin-drv = <3>; }; part-2 { samsung,pins = "gpk1-3", "gpk1-4", "gpk1-5", "gpk1-6"; samsung,pin-function = <4>; samsung,pin-pud = <4>; samsung,pin-drv = <3>; }; }; Tested on Exynos4210-Trats board and a custom Exynos4212-based one.

| * | | pinctrl: exynos: Consolidate irq_chips of GPIO and WKUP EINTsTomasz Figa2014-07-112-264/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling of irq_chip operations for GPIO and WKUP external interrupts is mostly the same, with the difference being offset of registers. However currently the driver has all the code duplicated for both EINT types, which is undesirable, because changes in irq_chip operations have to be done to both instances of the same code. This patch fixes this by creating exynos_irq_chip struct that has normal irq_chip struct embedded and contain differences between particular EINT types, which are three register offsets. One instance of code is removed and the new structure is used instead to fetch necessary data instead of samsung_pin_ctrl struct used previously. While at it, the patch removes Exynos-specific fields from aforementioned structure to improve layering of the driver.

The rationale behind this change is as follows: - pinctrl-samsung does not need translation from GPIO namespace to pinctrl namespace to handle GPIO operations - GPIO chip and offset therein are enough to calculate necessary offsets and bit masks in constant time, - the pinctrl_gpio_direction_*() functions do not do anything useful other than translating the pin into pinctrl namespace and calling the .gpio_set_direction() from pinmux_ops of the controller, - the undesirable side effect of using those helpers is losing the ability to change GPIO direction in atomic context, because they explicitly use a mutex for synchronization, Results of this patch are: - fixed warnings about scheduling while atomic in code that needs to set GPIO direction in atomic context (e.g. interrupt handler), - reduced overhead of bitbanging drivers that use gpio_direction_*(), e.g. i2c-gpio.
