2013-08-16ARM: mvebu: Fix the Armada 370/XP timer compatible stringsEzequiel Garcia
The "marvell,armada-370-xp-timer" compatible string, together with the "marvell,timer-25Mhz" property are deprecated and should be removed from current DT. Instead, the timer DT nodes are now required to have an appropriate compatible string, which should be either "marvell,armada-370-timer" or "marvell,armada-xp-timer", depending on SoC. The clock property is now required only for Armada 370 so move it accordingly. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

2013-08-16ARM: mvebu: use correct #interrupt-cells instead of #interrupts-cellsThomas Petazzoni
The Device Tree information for the GPIO banks of the Armada 370 and Armada XP SOCs was incorrectly using #interrupts-cells instead of controller when using GPIO interrupts, since the GPIO bank DT node wasn't recognized as a valid interrupt controller by the OF code.

2013-08-16ARM: dts: mxs: remove old DMA binding data from client nodesShawn Guo
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.

2013-08-16ARM: imx: clk-pllv3: improve the timeout waiting methodPeter Chen
There are two improvements for this commit: - Add comparing pll lock condition after while loop. It can fix potential fake timeout problem caused by the code is just scheduled out before compare the timeout, and the time of scheduling out are more than one jiffies. - Move timeout assignment more close to compare the timeout. It can reduce the possibility the code is scheduled out, and the timeout can be more precise.

2013-08-16ARM: imx6: change some clocks to fixup clocksLiu Ying

2013-08-16ARM: imx: add common clock support for fixup muxLiu Ying
One register may have several fields to control some clocks. It is possible that the read/write values of some fields may map to different real functional values, so writing to the other fields in the same register may break a working clock tree. A real case is the aclk_podf field in the register 'CCM Serial Clock Multiplexer Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook for multiplexer clock which is called before writing a value to clock registers to support this kind of multiplexer clocks.
