2015-08-26pinctrl: cherryview: Use raw_spinlock for lockingMika Westerberg1-35/+35
When running -rt kernel and an interrupt happens on a GPIO line controlled by Intel Cherryview/Braswell pinctrl driver we get: BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:917 in_atomic(): 1, irqs_disabled(): 1, pid: 0, name: swapper/0 Preemption disabled at:[<ffffffff81092e9f>] cpu_startup_entry+0x17f/0x480 CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.1.5-rt5 #16 ...

This is because desc->lock is raw_spinlock and is held when chv_gpio_irq_ack() is called by the genirq core. chv_gpio_irq_ack() in turn takes pctrl->lock which in -rt is an rt-mutex causing might_sleep() rightfully to complain about sleeping function called from invalid context. In order to keep -rt happy but at the same time make sure that register accesses get serialized, convert the driver to use raw_spinlock instead.

2015-08-26pinctrl: baytrail: Use raw_spinlock for lockingMika Westerberg1-25/+25
The Intel Baytrail pinctrl driver implements irqchip callbacks which are called with desc->lock raw_spinlock held. In mainline this is fine because spinlock resolves to raw_spinlock. However, running the same code in -rt we get: BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:917 in_atomic(): 1, irqs_disabled(): 1, pid: 0, name: swapper/0 Preemption disabled at:[<ffffffff81092e9f>] cpu_startup_entry+0x17f/0x480 CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.1.5-rt5 #13 ...

This is because in -rt spinlocks are preemptible so taking the driver private spinlock in irqchip callbacks causes might_sleep() to trigger. In order to keep -rt happy but at the same time make sure that register accesses get serialized, convert the driver to use raw_spinlock instead. Also shorten the critical section a bit in few places.

The pfc in the R8A7790 (and probably others in the R-Car gen 2 family) supports switching SDHI signals between 3.3V and 1.8V nominal voltage, and the SD driver should do that when switching to and from UHS modes. Add a flag for pins that have configurable I/O voltage and SoC operations to get and set the nominal voltage. Implement the pinconf power-source parameter using these operations.

2015-07-28pinctrl: kill off set_irq_flags usageRob Herring7-14/+0
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

2015-07-27pinctrl/ARM: move GPIO and pinctrl deps to device treeLinus Walleij5-82/+0

Since no systems with this are deployed we can just augment all device trees and the drivers at the same time and simplify the world.

2015-07-27pinctrl: sunxi: Add custom irq_domain_opsMaxime Ripard1-2/+33
The current interrupt parsing code was working by accident, because the default was actually parsing the first node of interrupts. While that was mostly working (and the flags were actually ignored), this binding has never been documented, and doesn't work with SoCs that have multiple interrupt banks anyway. Add a proper interrupt xlate function, that uses the same description than the GPIOs (<bank> <pin> <flags>), that will make things less confusing. The EINT number will still be used as the hwirq number, but won't be exposed through the DT.

This adds pinctrl and gpio driver to the CX92755 SoC "General Purpose Pin Mapping" hardware block. The CX92755 is one SoC from the Conexant Digicolor series. Pin mapping hardware supports configuring pins as either GPIO, or up to 3 other "client select" functions.
