tegra_pmc_parse_dt() references __initconst data. Fix it to be __init. This matches its only usage; a call from tegra_pmc_init() which is already __init.

2013-06-25pinctrl: st: Add pinctrl and pinconf support.Srinivas KANDAGATLA
This patch add pinctrl support to ST SoCs. About hardware: ST Set-Top-Box parts have two blocks called PIO and PIO-mux which handle pin configurations. Each multi-function pin is controlled, driven and routed through the PIO multiplexing block. Each pin supports GPIO functionality (ALT0) and multiple alternate functions(ALT1 - ALTx) that directly connect the pin to different hardware blocks. When a pin is in GPIO mode, Output Enable (OE), Open Drain(OD), and Pull Up (PU) are driven by the related PIO block. Otherwise the PIO multiplexing block configures these parameters and retiming the signal. About driver: This pinctrl driver manages both PIO and PIO-mux block using pinctrl, pinconf, pinmux, gpio subsystems. All the pinctrl related config information can only come from device trees.

2013-06-25pinctrl: remove bindings for pinconf options needing more thoughtHeiko Stübner
Some options currently take arguments in unspecified driver-specific units.

2013-06-25pinctrl: set unit for debounce time pinconfig to usecHeiko Stübner
Currently the debounce time pinconfig option uses an unspecified "time units" unit. As pinconfig options should use SI units and a real unit is also necessary for generic dt bindings, change it to usec. Currently no driver is using the generic pinconfig option for this, so the unit change is safe to do.

The use of wait_for_completion_interruptible is intentional so that we don't lock up the thread if a bug causes us to never wake up. This bug is caused by the helper thread using the larval without holding a reference count on it. If the helper thread completes after the original thread requesting for help has gone away and destroyed the larval, then we get the crash above. So the fix is to hold a reference count on the larval.

2013-06-25pinctrl: rip out the direct pinconf APILinus Walleij
From the inception ot the pin config API there has been the possibility to get a handle at a pin directly and configure its electrical characteristics. For this reason we had: int pin_config_get(const char *dev_name, const char *name, unsigned long *config); int pin_config_set(const char *dev_name, const char *name, unsigned long config); int pin_config_group_get(const char *dev_name, const char *pin_group, unsigned long *config); int pin_config_group_set(const char *dev_name, const char *pin_group, unsigned long config); After the introduction of the pin control states that will control pins associated with devices, and its subsequent introduction to the device core, as well as the introduction of pin control hogs that can set up states on boot and optionally also at sleep, this direct pin control API is a thing of the past. As could be expected, it has zero in-kernel users. Let's delete this API and make our world simpler.

2013-06-25genirq: Add irq_get_trigger_type() to get IRQ flagsJavier Martinez Canillas
Drivers that want to get the trigger edge/level type flags for a given interrupt have to call irq_get_irq_data(irq) to get the struct irq_data and then irqd_get_trigger_type(irq_data) to obtain the IRQ flags. This is not only error prone but also unnecessary exposes the struct irq_data to callers. It's better to have an irq_get_trigger_type() function to obtain the edge/level flags for an IRQ.

2013-06-25ASoC: adau1701: allow configuration of PLL mode pinsDaniel Mack
The ADAU1701 has 2 hardware pins to configure the PLL mode in accordance to the MCLK-to-LRCLK ratio. These pins have to be stable before the chip is released from reset, and a full reset cycle, including a new firmware download is needed whenever they change. This patch adds GPIO properties to the DT bindings of the Codec, and implements makes the set_sysclk memorize the configured sysclk. Because the run-time parameters are unknown at probe time, the first firmware download is postponed to the first hw_params call, when the driver can determine the mclk/lrclk divider. Subsequent downloads are only issued when the divider configuration changes.

2013-06-25ASoC: tas5086: add support for pwm start mode configDaniel Mack
The TAS5086 has two alternative modes to start its PWM channels, Mid-Z and Low-Z. Which one to use depends on how the PWM power stages are connected to the TAS5086. This patch adds 6 optional boolean properties to the DT bindings of the driver which allow the user to configure each individual channel to the Mid-Z scheme, and leaves all the others to the default (Low-Z).
