| * | | pinctrl: sunxi: Add A80 pinctrl muxing optionsMaxime Ripard2014-10-303-0/+754
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The A80 has a rather usual pin controller, the only thing out of the ordinary being that it has 5 interrupts banks, and that some pins have several options for the same functions.

| * | | pinctrl: mxs: warn if functions are not grouped by nameUwe Kleine-König2014-10-301-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mxs pinctrl driver cannot handle when functions are not grouped by name (which IMO is a bug). This happens for example if a imx28-somemachine.dts provides a function that has the same name as a function defined in imx28.dtsi. The proper way to fix that would be to check for duplicates in the loops (which increases parsing time) or parse the groups first and sort the resulting array.

| * | | pinctrl: pinconf-generic: Add flag to print argumentsSoren Brinkmann2014-10-281-28/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When dumping pinconf information in debugfs, config arguments are only printed when a unit is present and the argument is != 0. For parameters like the slew rate, this does not work. The slew rate uses a driver specific format for the argument, i.e. 0 can be a valid argument and a unit is not provided for it. For that reason, add a flag to enable printing the argument instead of inferring it from the presence of a unit and the value of the argument.

This was done to avoid having a custom <asm/gpio.h> header for the x86 architecture - GPIO is custom and complicated enough as it is already! We want to move to a radix to store the descriptors going forward, and finally get rid of this fixed array size altogether. - Endgame patching of the gpio_remove() semantics initiated by Abdoulaye Berthe. It is not accepted by the system that the removal of a GPIO chip fails during eg reboot or shutdown, and therefore the return value has now painfully been refactored away. For special cases like GPIO expanders on a hot-pluggable bus like USB, we may later add some gpiochip_try_remove() call, but for the cases we have now, return values are moot. - Some incremental refactoring of the gpiolib core and ACPI GPIO library for more descriptor usage. - Refactor the chained IRQ handler set-up method to handle also threaded, nested interrupts and set up the parent IRQ correctly. Switch STMPE and TC3589x drivers to use this registration method. - Add a .irq_not_threaded flag to the struct gpio_chip, so that also GPIO expanders that block but are still not using threaded IRQ handlers. - New drivers for the ARM64 X-Gene SoC GPIO controller. - The syscon GPIO driver has been improved to handle the "DSP GPIO" found on the TI Keystone 2 SoC:s. - ADNP driver switched to use gpiolib irqchip helpers. - Refactor the DWAPB driver to support being instantiated from and MFD cell (platform device). - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP, Xilinx and Crystalcove drivers. - Various minor fixes" * tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (52 commits) gpio: pch: Build context save/restore only for PM pinctrl: abx500: get rid of unused variable gpio: ks8695: fix 'else should follow close brace '}'' gpio: stmpe: add verbose debug code gpio: stmpe: fix up interrupt enable logic gpio: staticize xway_stp_init() gpio: handle also nested irqchips in the chained handler set-up gpio: set parent irq on chained handlers gpiolib: irqchip: use irq_find_mapping while removing irqchip gpio: crystalcove: support virtual GPIO pinctrl: bcm281xx: make Kconfig dependency more strict gpio: kona: enable only on BCM_MOBILE or for compile testing gpio, bcm-kona, LLVMLinux: Remove use of __initconst gpio: Fix ngpio in gpio-xilinx driver gpio: dwapb: fix pointer to integer cast gpio: xgene: Remove unneeded #ifdef CONFIG_OF guard gpio: xgene: Remove unneeded forward declation for struct xgene_gpio gpio: xgene: Fix missing spin_lock_init() gpio: ks8695: fix switch case indentation gpiolib: add irq_not_threaded flag to gpio_chip ...

| * | | pinctrl: at91: Fix error handling while doing gpiochio_irqchip_addPramod Gurav2014-09-231-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | pinctrl: imx: detect uninitialized pinsStefan Agner2014-09-233-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | pinctrl: at91: add drive strength configurationMarek Roszko2014-09-051-1/+161

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
