Add alias for gpio nodes, so that gpio driver can identify the port
number and then specify a sensible gpio base rather than using the
one dynamically allocated by gpio core.

- New driver for AMD-8111 southbridge GPIOs
- New driver for Wolfson Micro Arizona devices
- Propagate device tree parse errors
- Probe deferral finalizations - all expected calls to
GPIO will now hopefully request deferral where apropriate
- Misc updates to TCA6424, WM8994, LPC32xx, PCF857x, Samsung
MXC, OMAP and PCA953X drivers.

- New driver for AMD-8111 southbridge GPIOs
- New driver for Wolfson Micro Arizona devices
- Propagate device tree parse errors
- Probe deferral finalizations - all expected calls to GPIO will now
hopefully request deferral where apropriate
- Misc updates to TCA6424, WM8994, LPC32xx, PCF857x, Samsung MXC, OMAP

gpio: of_get_named_gpio_flags() return -EPROBE_DEFER if GPIO not yet available
gpiolib: Defer failed gpio requests by default
MAINTAINERS: add entry OMAP GPIO driver
gpio/pca953x: increase variables size to support 24 bit of data
GPIO: PCA953X: Increase size of invert variable to support 24 bit
gpio/omap: move bank->dbck initialization to omap_gpio_mod_init()
gpio/mxc: use the edge_sel feature if available
gpio: propagate of_parse_phandle_with_args errors
gpio: samsung: add flags specifier to device-tree binding
gpiolib: Add support for Wolfson Microelectronics Arizona class devices
gpio: gpio-lpc32xx: Add gpio_to_irq mapping
gpio: pcf857x: share 8/16 bit access functions
gpio: LPC32xx: Driver cleanup
MAINTAINERS: Add Wolfson gpiolib drivers to the Wolfson entry
gpiolib: wm8994: Convert to devm_kzalloc()
gpiolib: wm8994: Use irq_domain mappings for gpios
gpio: add a driver for GPIO pins found on AMD-8111 south bridge chips
gpio/tca6424: merge I2C transactions, remove cast
gpio/of: fix a typo of comment message
Some mxc processors have an edge_sel feature, which allows the IRQ to be
triggered by any edge.
This patch makes use of this feature if available, which skips mxc_flip_edge().

Change the value of #interrupt-cells of gpio nodes from 1 to 2, so that
the gpio irq type can be specified in device tree. Also update binding
document to make it clear.

It has been pointed out by device tree maintainer for several times
that the generic names 'serial' and 'ethernet' should be used for
those devices per ePAPR. Renames imx uart and fec device tree nodes
to stop them being bad examples.
