2014-03-12pinctrl: msm: drop wake_irqs bitmapJosh Cartwright1-13/+1
Currently, the wake_irqs bitmap is used to track whether there are any gpio's which are configured as wake irqs, and uses this to determine whether or not to call enable_irq_wake()/disable_irq_wake() on the summary interrupt. However, the genirq core already handles this case, by maintaining a 'wake_count' per irq_desc, and only calling into the controlling irq_chip when wake_count transitions 0 <-> 1. Drop this bitmap, and unconditionally call irq_set_irq_wake() on the summary interrupt.

2014-03-05pinctrl: sunxi: use chained_irq_{enter, exit} for GIC compatibilityChen-Yu Tsai1-0/+4
On tha Allwinner A20 SoC, the external interrupts on the pin controller device are connected to the GIC. Without chained_irq_{enter, exit}, external GPIO interrupts, such as used by mmc core card detect, cause the system to hang. This issue was first encountered during my attempt to get out-of-band interrupts for WiFi on the Cubietruck working. With David's new series of sunci-mci using mmc slot-gpio for (GPIO interrupt based) card detection, removing the SD card also causes my Cubietruck to hang. This problem should extend to all Allwinner A20 based boards. With this fix, the system no longer hangs when I remove or insert the SD card. /proc/interrupts show that the interrupt has correctly fired. However the system still does not detect card removal/insertion. I believe this is another unrelated issue.

2014-02-25pinctrl: mvebu: add pin-muxing driver for the Marvell Armada 380/385Thomas Petazzoni3-0/+467
The Marvell Armada 380/385 are new ARM SoCs from Marvell, part of the mvebu family, but using a Cortex-A9 CPU core. In terms of pin-muxing, it is similar to Armada 370 and XP for the register layout, only different in the number of available pins and their functions. Therefore, we simply use the existing drivers/pinctrl/mvebu/ infrastructure, with no other changes that the list of pins and corresponding functions.

2014-02-25pinctrl: mvebu: add pin-muxing driver for the Marvell Armada 375Thomas Petazzoni3-0/+464
The Marvell Armada 375 is a new ARM SoC from Marvell, part of the mvebu family, but using a Cortex-A9 CPU core. In terms of pin-muxing, it is similar to Armada 370 and XP for the register layout, only different in the number of available pins and their functions. Therefore, we simply use the existing drivers/pinctrl/mvebu/ infrastructure, with no other changes that the list of pins and corresponding functions.

2014-02-25pinctrl: mvebu: remove MPP_REG_CTRL macroThomas Petazzoni1-16/+3
Now that each per-SoC pinctrl driver must implement its own get/set functions, there is no point in keeping the MPP_REG_CTRL macro, whose purpose was to let the core pinctrl mvebu driver use default get/set functions.

pinctrl-mvebu allows SoCs to pass unnamed controls that will get an auto-generated name of "mpp<PIN#>". Currently, we are allocating name buffers on a per-control basis while looping over passed controls. This counts the total number of unnamed controls and allocates a global name buffer instead. The new buffer is then used while assigning controls to pinctrl groups later.
