Pull ARM SoC DT updates from Olof Johansson:
"Most of this branch consists of updates, additions and general churn
of the device tree source files in the kernel (arch/arm/boot/dts).
Besides that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board
files for various platforms.
- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as
well
- Some updates to pinctrl and other subsystems. Most of these are
for DT-enablement of the various platforms and acks have been
collected"

The delay units inside the LRADC depend on the presence of a 2 kHz clock.
This change enables the clock to be able to use the delay unit for the
touchscreen part of the driver.

Convert mx23/mx28 dts filed to use the pinctrl header files.
NOTE: During automatic conversion of these files to use the pinconfig
definitions an inconsistency has been found in:
arch/arm/boot/dts/imx28-apx4devkit.dts
According to the comment the function for pad SSP2_SS0 should have
been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131
represents: MX28_PAD_SSP2_SS0__AUART3_TX
I used the later (though probably wrong) definition because that's
what is actually being used in the DTB.

After providing spi alias, we can get the following message during probe:
m25p80 spi1.0: sst25vf016b (2048 Kbytes)
,which looks better than the original one:
m25p80 spi32766.0: sst25vf016b (2048 Kbytes)
While at it, keep the alias entries in alphabetical order.

After mxs-dma driver adopts generic DMA device tree binding, channel
interrupt number is defined in DMA controller node, and channel ID is
listed in "dmas" property. So the DMA channel interrupt number in
client nodes' "interrupts" property and fsl,<module>-dma-channel which
are used by old customized DMA binding can be removed now.

Add generic DMA device tree binding for mxs-dma. The changes include:
* Add channel interrupts into DMA controller nodes
* Add properties '#dma-cells' and 'dma-channels' for DMA controller nodes
* And properties 'dmas' and 'dma-names' for DMA client nodes
* Update mxs-dma device tree binding doc

Instead of using static address definition, get reset address from
device tree with mapping, so that core_initcall mxs_arch_reset_init()
can be killed.
The "rtc" clock code in mxs_arch_reset_init() seems to be zombie, since
there is no clk lookup defined in clock driver at all. Remove it
together.

The current DT nodes for mx23/mx28 miss the `clocks-names` item for gpmi-nand.
So the gpmi-nand driver could not find the proper clock.

It really becomes a maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.
Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx23 client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.
