2015-07-28gpio: mpc8xxx: Convert mpc8xxx_gpio_chip.lock to raw_spinlockAlexander Stein
mpc8xxx_gpio_chip.lock needs to be a real spinlock in preempt-rt. Especially the interrupt related functions can not be converted to a sleeping lock.

2015-07-28gpio: defer probe if pinctrl cannot be foundTomeu Vizoso
When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER if the pin controller isn't available. Otherwise, the GPIO range wouldn't be set at all unless the pin controller probed always before the GPIO chip. With this change, the probe of the GPIO chip will be deferred and will be retried at a later point, hopefully once the pin controller has been registered and probed already.

2015-07-28gpio: kill off set_irq_flags usageRob Herring
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 as most platforms don't use probing. There appears to be a great deal of blind copy and paste of this code.

2015-07-27gpio: omap: use raw locks for lockingSebastian Andrzej Siewior
This patch converts gpio_bank.lock from a spin_lock into a raw_spin_lock. The call path is to access this lock is always under a raw_spin_lock, for instance - __setup_irq() holds &desc->lock with irq off + __irq_set_trigger() + omap_gpio_irq_type() - handle_level_irq() (runs with irqs off therefore raw locks) + mask_ack_irq() + omap_gpio_mask_irq() This fixes the obvious backtrace on -RT. However the locking vs context is not and this is not limited to -RT: - omap_gpio_irq_type() is called with IRQ off and has an conditional call to pm_runtime_get_sync() which may sleep. Either it may happen or it may not happen but pm_runtime_get_sync() should not be called with irqs off. - omap_gpio_debounce() is holding the lock with IRQs off. + omap2_set_gpio_debounce() + clk_prepare_enable() + clk_prepare() this one might sleep. The number of users of gpiod_set_debounce() / gpio_set_debounce() looks low but still this is not good.

into devel The last patch in this series makes the flags parameter for the various gpiod_get* functions mandatory and so allows to remove an ugly cpp hack introduced in commit 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) for v3.17-rc1. The other nine commits fix the last remaining users of these functions that don't pass flags yet. (Only etraxfs-uart wasn't fixed; this driver's use of the gpiod functions needs fixing anyhow.)

2015-07-16gpio: rcar: Fine-grained Runtime PM supportGeert Uytterhoeven
Currently gpio modules are runtime-resumed at probe time. This means the gpio module will be active all the time (except during system suspend, if not configured as a wake-up source). While an R-Car Gen2 gpio module retains pins configured for output at the requested level while put in standby mode, gpio registercannot be accessed while suspended. Unfortunately pm_runtime_get_sync() cannot be called from all contexts where gpio register access is needed. Hence move the Runtime PM handling from probe/remove time to gpio request/free time, which is probably the best we can do. On r8a7791/koelsch, gpio modules 0, 1, 3, and 4 are now suspended during normal use (gpio2 is used for LEDs and regulators, gpio5 for keys, gpio6 for SD-Card CD & WP, gpio7 for keys and regulators).
