Linus Torvalds db5b0ae007 ARM: arm-soc: device tree conversions and enablement
Continued device tree conversion and enablement across a number of
 platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
 smaller series as well.
 
 ux500 has seen continued conversion for platforms. Several platforms have
 seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
 is adding data for new devices/drivers, and Exynos has a bunch of new
 bindings and devices added as well.
 
 So, pretty much the same progression in the right direction as the last
 few releases.

Lee Jones 79b40753a3 ARM: ux500: List DT compatibility using platform names rather than by board
So far, each ST-Ericsson board supported by Device Tree has been similar
enough to run though a single DT_MACHINE_INIT call. On the back of that
it has been suggested that we should reduce the number of compatible
strings in our dt_compat structure. After subsequent discussion with Arnd
Bergmann the conclusion was to list entries by platform as opposed to by
board.

The other suggestion was to use a single string which would cover all
supported platforms, but any wildcard entries would include unsupported
chipsets, such as the u5500 and potential new chips which no not yet have
DT functionality. Hence, the best solution which encompasses all supported
platforms, but no unsupported ones was to list the currently enabled four
chipsets; u8500, u8540, u9500 and u9540 instead.

Regulator supply names should be allocated by board rather than
per SoC, as the same SoC could be wired differently on varying
hardware. Here we push all regulator-name allocation out to the
dbx5x0 subordinate board files; HREF and Snowball.

This patch applies the correct format requested by the irq
domain. For chained IRQs which use GPIO lines as IRQs, we
stipulate that a two cell request is required. The first cell
contains the requested IRQ and the second can contain flags
pertaining to edge detection and level sensitive values. The
zeroth cell specifies the GPIO controller by use of a phandle.

Here we split the description of the external-bus@50000000 over
two description files. In the more generic db8500 description file
we only specify the external-bus. Normally this would be used to
communicate with a NOR-flash device. On the Snowball however, the
SMSC9115 Ethernet chip occupies it. In the Snowball board specific
description file is where we actually specify that it is in fact the
Ethernet device which lives here.

This adds all devices that are normally present through the
u8500_init_machine function in the device tree as well, which
will duplicate the devices that are visible.

This will not do much by itself because the device from the
device tree are not matched by any device driver until they
are converted as well. The next step is to move over one
device at a time to actually be used from the device tree
instead of the hardcoded device using auxdata to pass the
correct platform_data.
