2014-11-09pinctrl: exynos: Add support for Exynos4415Tomasz Figa
The pin controllers of Exynos4415 are similar to Exynos4412, but certain differences cause the need to create separate driver data for it. This patch adds pin controller and bank descriptor arrays to the driver to support the new SoC.

2014-11-09pinctrl: exynos: Add irq_chip instance for Exynos7 wakeup interruptsAbhilash Kesavan
Exynos7 uses different offsets for wakeup interrupt configuration registers. So a new irq_chip instance for Exynos7 wakeup interrupts is added. The irq_chip selection is now based on the wakeup interrupt controller compatible string.

2014-11-09pinctrl: exynos: Consolidate irq domain callbacksAbhilash Kesavan
Adding a irq_chip field to the samsung_pin_bank struct helps in consolidating the irq domain callbacks for external gpio and wakeup interrupt controllers. The exynos_wkup_irqd_ops and exynos_gpio_irqd_ops have now been merged into a single exynos_eint_irqd_ops.

2014-11-09pinctrl: exynos: Generalize the eint16_31 demux codeAbhilash Kesavan
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.

2014-11-09pinctrl: samsung: Separate per-bank init and runtime dataTomasz Figa
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>
2014-11-09pinctrl: samsung: Constify samsung_pin_ctrl structTomasz Figa
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>
2014-11-09pinctrl: samsung: Constify samsung_pin_bank_type structTomasz Figa
This structure is not intended to be modified at runtime and functions as constant data shared between multiple pin banks. This patch makes all instances of it constant across the driver. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com>
2014-11-09pinctrl: samsung: Drop unused label field in samsung_pin_ctrl structTomasz Figa
There is no code using it and in fact there are pin controller variants that do not even have this field initialized in their init data. This patch removes it completely. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com>
2014-11-09pinctrl: samsung: Make samsung_pinctrl_get_soc_data use ERR_PTR()Tomasz Figa
Currently the function returns a valid pointer on success and NULL on error, so exact error code is lost. This patch changes return convention of the function to use ERR_PTR() on error instead. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com>

2014-10-30pinctrl: mxs: warn if functions are not grouped by nameUwe Kleine-König
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.

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.

2014-10-29pinctrl: rockchip: Set wake_enabledDoug Anderson
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".

2014-10-28pinctrl: pinconf-generic: Add flag to print argumentsSoren Brinkmann
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.
