The port controller IP found in the Allwinner A10 and A13 can use few of
the pins it manage as an interrupt source, called external interrupts in
the datasheet.
The number of these external interrupts are SoCs specific, but the
current upper limit is 32. In order to work, the external interrupts'
pins have to be muxed to a specific function to generate an interrupt.
This patch adds the irqchip and the needed logic to use the PIO
controller as an interrupt controller.

There exist controllers that don't support to set the pull to up or down
separately but instead automatically set the pull direction based on
embedded knowledge inside the controller, for example depending on the
selected mux function of the pin.
Therefore this patch adds another config option to use this default
pull-state for a pin where it is not possible to know or decide if the
pin will be pulled up or down.

The pinctrldev_list_mutex is sinked into the functions that

much more sense in this way. All the callers are in
non-performance critical paths and the code is way more

atlas6 is a SoC very similar with primaII, the register layput of
pinctrl is same, but the pads, groups and functions of atlas6 have
different layout with prima2, this patch
1. pull the definition of pads, groups and functions out of the
pinctrl-sirf driver,and put them into soc-specific files
2. add pads, groups and functions tables for atlas6
3. let pads, groups and functions tables become the config data of
the related dt compatible node, so the pinctrl-sirf can support
all SiRF SoCs with the config data as private data.
In this patch,we create a sirf dir, and let
the old drivers/pinctrl/pinctrl-sirf.c =
drivers/pinctrl/sirf/pinctrl-prima2.c +
drivers/pinctrl/sirf/pinctrl-sirf.c
drivers/pinctrl/sirf/pinctrl-atlas6.c is a newly created file for the

Merge tag 'renesas-fixes-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes
From Simon Horman, Renesas ARM based SoC fixes for v3.10:
- Correction to USB OVC and PENC pin groupings on r8a7779 SoC.
This avoids conflicts when the USB_OVCn pins are used by another function.
This has been observed to be a problem in v3.10-rc1.
- Update CMT clock rating for sh73a0 SoC to resolve boot failure
on kzm9g-reference. This resolves a regression between v3.9 and v3.10-rc1.

When user interrupts ongoing transfers the dmatest may end up with console
lockup, oops, or data mismatch. This patch prevents user to abort any ongoing
test.
Documentation is updated accordingly.

Commit b378549 (ACPI / PM: Do not power manage devices in unknown
initial states) added code to force devices without _PSC, but having
_PS0 defined in the ACPI namespace, into ACPI power state D0 by
executing _PS0 for them. That turned out to break Toshiba P870-303,
however, so revert that code.
