e9069cf8b7 arm: vt8500: Add pinctrl driver for arch-vt8500
This series adds support for the pinctrl/gpio module on all arch-vt8500
 supported SoCs.
 
 As part of the review process, some tidy up is also done to
 drivers/of/base.c to remove some code that is being constantly duplicated.
 
 Also, a patch for the bcm2835 pinctrl driver is included to take advantage
 of the new of/base.c code.

This patch adds support for the GPIO/pinmux controller found on the VIA
VT8500 and Wondermedia WM8xxx-series SoCs.

Each pin within the controller is capable of operating as a GPIO or as
an alternate function. The pins are numbered according to their control
bank/bit so that if new pins are added, the existing numbering is maintained.

All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and
WM8850.

daeec1f083 of: Remove duplicated code for validating property and value
Several functions in of/base.c have the same code duplicated for
finding and validating a property and value.

struct property *prop = of_find_property(np, propname, NULL);
if (!prop)
	return -EINVAL;
if (!prop->value)
	return -ENODATA;
if (<some length> > prop->length)
	return -EOVERFLOW;

This patch adds of_find_property_value_of_size() which performs the
equivalent of the above code and removes the instances where it was
duplicated in several functions.

427cc72027 irqchip: intc-irqpin: Add support for shared interrupt lines
On some hardware we don't have a 1-1 mapping from the external
interrupts coming from INTC to the GIC SPI pins. We can however
share lines to demux incoming IRQs on these SoCs.

This patch enables the intc_irqpin driver to detect requests for shared
interrupt lines and demuxes them properly by querying the INTC INTREQx0A
registers.

If you need multiple shared intc_irqpin device instances, be sure to mask
out all interrupts on the INTC that share the one line before you start
to register them. Else you run into IRQ floods that would be caused by
interrupts for which no handler has been set up yet when the first
intc_irqpin device is registered.

c19b3b0f6e KMS: fix EDID detailed timing frame rate
When KMS has parsed an EDID "detailed timing", it leaves the frame rate
zeroed.  Consecutive (debug-) output of that mode thus yields 0 for
vsync.  This simple fix also speeds up future invocations of
drm_mode_vrefresh().

While it is debatable whether this qualifies as a -stable fix I'd apply
it for consistency's sake; drm_helper_probe_single_connector_modes()
does the same thing already for all probed modes.

16dad1d743 KMS: fix EDID detailed timing vsync parsing
EDID spreads some values across multiple bytes; bit-fiddling is needed
to retrieve these.  The current code to parse "detailed timings" has a
cut&paste error that results in a vsync offset of at most 15 lines
instead of 63.

See

   http://en.wikipedia.org/wiki/EDID

and in the "EDID Detailed Timing Descriptor" see bytes 10+11 show why
that needs to be a left shift.

38d78e587d mqueue: sys_mq_open: do not call mnt_drop_write() if read-only
mnt_drop_write() must be called only if mnt_want_write() succeeded,
otherwise the mnt_writers counter will diverge.

mnt_writers counters are used to check if remounting FS as read-only is
OK, so after an extra mnt_drop_write() call, it would be impossible to
remount mqueue FS as read-only.  Besides, on umount a warning would be
printed like this one:
