* pinctrl: exynos: Generalize the eint16_31 demux codeAbhilash Kesavan2014-11-092-4/+12
| | | | | | | | | | | | | | | | The function exynos_irq_demux_eint16_31 uses pre-defined offsets for external interrupt pending status and mask registers. So this function is not extensible for Exynos7 SoC which has these registers at different offsets. Generalize the exynos_irq_demux_eint16_31 function by using the pending/mask register offset values from the exynos_irq_chip structure. This is done by adding a irq_chip field to the samsung_pin_bank struct.

* pinctrl: samsung: Separate per-bank init and runtime dataTomasz Figa2014-11-095-33/+72
| | | | | | | | | | | | | | Currently the driver mixes constant init data with runtime data, which is far from being elegant and can invite potential hard to track issues. This patch intends to solve this by introducing a new samsung_pin_bank_data structure to hold only constant data known at compile time, which can be copied to main samsung_pin_bank struct used at runtime. In addition, thanks to this change, all per-bank initdata can be marked with const and __initconst keywords and dropped after init completes. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com>
* pinctrl: samsung: Constify samsung_pin_ctrl structTomasz Figa2014-11-095-95/+97
| | | | | | | | | | In order to separate initialization constants from runtime data, this patch modifies the driver to store only constant data in samsung_pin_ctrl struct and copy data required at runtime to samsung_pinctrl_drv_data struct. This makes it possible to mark all existing instances of samsung_pin_ctrl struct as const and __initconst. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com>
* pinctrl: samsung: Constify samsung_pin_bank_type structTomasz Figa2014-11-095-26/+24

* pinctrl: Add Intel Cherryview/Braswell pin controller supportMika Westerberg2014-11-043-0/+1532
| | | | | | | | | | | | This driver supports the pin/GPIO controllers found in newer Intel SoCs like Cherryview and Braswell. The driver provides full GPIO support and minimal set of pin controlling funtionality. The driver is based on the original Cherryview GPIO driver authored by Ning Li and Alan Cox.

* gpio / ACPI: Add knowledge about pin controllers to acpi_get_gpiod()Mika Westerberg2014-11-041-3/+59
| | | | | | | | | | | | | | | | | | | | The GPIO resources (GpioIo/GpioInt) used in ACPI contain a GPIO number which is relative to the hardware GPIO controller. Typically this number can be translated directly to Linux GPIO number because the mapping is pretty much 1:1. However, when the GPIO driver is using pins exported by a pin controller driver via set of GPIO ranges, the mapping might not be 1:1 anymore and direct translation does not work. In such cases we need to translate the ACPI GPIO number to be suitable for the GPIO controller driver in question by checking all the pin controller GPIO ranges under the given device and using those to get the proper GPIO number.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pin_config_set() The Rockchip pinctrl driver was calling rockchip_gpio_direction_output() in the pin_config_set() callback. This was just a shortcut for: * rockchip_gpio_set() * pinctrl_gpio_direction_output() Unfortunately it's not so good to call pinctrl_gpio_direction_output() from pin_config_set(). Specifically when initting hogs you'll get an error. Let's refactor a little so we can call _rockchip_pmx_gpio_set_direction() directly.

| * pinctrl: rockchip: Set wake_enabledDoug Anderson2014-10-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The rockchip pinctrl driver uses irq_gc_set_wake() but doesn't setup the .wake_enabled member. That means that we can never actually use a pin for wakeup. When "irq_set_irq_wake()" tries to call through it will always get a failure from set_irq_wake_real() and will then set wake_depth to 0. Assuming you can resume you'll later get an error message about "Unbalanced IRQ x wake disable".

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly set the dr_mode for the second dwc3 controller on the Arndale Octa board to host mode. This is required to ensure the controller is initialized in the right mode if the kernel is build with USB gadget support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the optional dr_mode property isn't set in the dwc3 nodes the the controller will go into OTG mode if both USB host and USB gadget functionality are enabled in the kernel configuration. Unfortunately this results in USB not working on exynos5420-peach-pit and exynos5800-peach-pi with such a kernel configuration unless manually change the mode. To resolve that explicitly configure the dual role mode as host.
