Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: device tree work" from Arnd Bergmann:
"Most of these patches convert code from using static platform data to
describing the hardware in the device tree. This is only the first
half of the changes for v3.4 because a lot of patches for this topic
came in the last week before the merge window.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>"
Fix up trivial conflicts in arch/arm/mach-vexpress/{Kconfig,core.h}

1 | * Advanced Interrupt Controller (AIC) | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: Should be "atmel,<chip>-aic" | ||
5 | - interrupt-controller: Identifies the node as an interrupt controller. | ||
6 | - interrupt-parent: For single AIC system, it is an empty property. | ||
7 | - #interrupt-cells: The number of cells to define the interrupts. It sould be 2. | ||
8 | The first cell is the IRQ number (aka "Peripheral IDentifier" on datasheet). | ||
9 | The second cell is used to specify flags: | ||
10 | bits[3:0] trigger type and level flags: | ||
11 | 1 = low-to-high edge triggered. | ||
12 | 2 = high-to-low edge triggered. | ||
13 | 4 = active high level-sensitive. | ||
14 | 8 = active low level-sensitive. | ||
15 | Valid combinations are 1, 2, 3, 4, 8. | ||
16 | Default flag for internal sources should be set to 4 (active high). | ||
17 | - reg: Should contain AIC registers location and length | ||
18 | |||

20 | /* | ||
21 | * AIC | ||
