9652e8bd16 ARM: SPEAr600: Add device-tree support to SPEAr600 boards
This patch adds a generic target for SPEAr600 board that can be
configured via the device-tree. Currently the following devices
are supported via the devicetree:

- VIC interrupts
- PL011 UART
- PL061 GPIO
- Synopsys DW I2C
- Synopsys DW ethernet

Other peripheral devices (e.g. SMI flash, FSMC NAND flash etc) will
follow in later patches.

Only the spear600-evb is currently supported. Other SPEAr600
based boards will follow later.

Since the current mainline SPEAr600 code only supports the SPEAr600
evaluation board, with nearly zero peripheral devices (only UART
and GPIO), it makes sense to switch over to DT based configuration
completely now. So this patch also removes all non-DT stuff, mainly
platform device data. The files spear600.c and spear600_evb.c are
removed completely.

This adds patches from Lee Jones, Niklas Hernaeus and myself to provide
initial device tree support on the ux500 platform. The pull request from
Lee contained some other changes, so I rebased the patches on top of
the branches that are actually dependencies for this.

7e0ce270b2 ARM: ux500: db8500: list most devices in the snowball device tree
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.

This provides very basic Device Tree support for ST-Ericsson's
low-cost development platform, Snowball. If Device Tree for
ux500 is enabled and the correct board is configured within the
Device Tree blob, the correct *_init_machine() will be called.

9248510469 ARM: smp_twd: remove old local timer interface
Now that all users of the previous local timer interface
have been converted to the runtime registration API, make
this interface the only one supported for this driver.

58458e0327 ARM: imx6q: convert to twd_local_timer_register() interface
Add support for the new smp_twd runtime registration interface
to the imx6q platforms, and remove the old compile-time support.

The imx6q DTS file is updated to match the TWD DT documentation.
Also present in this patch a DTS fix to the timer interrupt routing
(the PPI connection uses bits [15:8]) and trigger (rising edge).
