Pull ARM SoC device tree changes from Arnd Bergmann: "A large part of the arm-soc patches are nowadays DT changes, adding support for new SoCs, boards and devices without changing kernel source. The plan is still to move the devicetree files out of the kernel tree and reduce the amount of churn going on here, but we keep finding reasons to delay doing that. Changes are really all over the place, with little sticking out particularly. We have contributions from a total of 116 people in this branch. Unfortunately, the size of this branch also causes a significant number of conflicts at the moment, typically when subsystem maintainers merge patches that change the driver at the same time as the dts files. In most cases this could be avoided because the dts changes are supposed to be compatible in both ways, and we are asking everyone to send ARM dts changes through our tree only" * tag 'dt-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (541 commits) dts: stmmac: Document the clocks property in the stmmac base document dts: socfpga: Add DTS entry for adding the stmmac glue layer for stmmac.

2014-03-12ARM: OMAP2+: extend iommu pdata-quirks to OMAP5Suman Anna1-0/+4
OMAP5 has the same iommus as OMAP4, so extend the OMAP4 iommu pdata quirks for OMAP5 as well. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-03-12ARM: OMAP2+: use pdata quirks for iommu reset linesSuman Anna1-0/+20
The OMAP iommu driver performs the reset management for the iommu instances in processor sub-systems using the omap_device API which are currently supplied as platform data ops. Use pdata quirks to maintain the functionality as the OMAP iommu driver gets converted to use DT nodes, until the reset portions are decoupled from omap_hwmod/omap_device into a separate reset driver. This patch adds the pdata quirks for the reset management of iommus within the DSP (OMAP3 & OMAP4) and IPU subsystems (OMAP4).

sbc-t3x boards features two external USB ports on SB-T35 baseboard. The baseboardi USB hub reset signal should be de-asserted to make those ports functional. sbc-t3517 features additional (assembled on CoM) USB hub which also requires reset signal handling.

2013-12-18ARM: dts: Add support for sbc-3xxx with cm-t3730Tony Lindgren1-0/+31
This adds support for CompuLab SBC-T3530, also known as cm-t3730: http://compulab.co.il/products/sbcs/sbc-t3530/ It seems that with the sbc-3xxx mainboard is also used on SBC-T3517 and SBC-T3730 with just a different CPU module: http://compulab.co.il/products/sbcs/sbc-t3517/ http://compulab.co.il/products/sbcs/sbc-t3730/ So let's add a common omap3-sb-t35.dtsi and then separate SoC specific omap3-sbc-t3730.dts, omap3-sbc-t3530.dts and omap3-sbc-t3517.dts. I've tested this with SBC-T3730 as that's the only one I have. At least serial, both Ethernet controllers, MMC, and wl12xx WLAN work. Note that WLAN seems to be different for SBC-T3530. And SBC-T3517 may need some changes for the EMAC Ethernet if that's used instead of the smsc911x.

2013-12-08ARM: OMAP2+: Use pdata quirks for emac on am3517Tony Lindgren1-0/+43
As the emac uses the system control module registers for reset and interrupts, we need to pass those in the platform data until we have a separate system control module driver. Signed-off-by: Tony Lindgren <tony@atomide.com>
2013-12-08ARM: OMAP2+: Add support for legacy auxdata for twlTony Lindgren1-0/+16
As we currently need to support a mix of legacy platform data and device tree intialized data, let's make sure things keep working for the TWL GPIOs. Mostly the issue is caused by the fact that DSS does not yet have device tree bindings, so we need to rely on the TWL GPIO callback for setting up things like LCD backlight for some boards. As of_platform_populate() for the TWL GPIO is called by twl-core after the I2C bus has been initialized, we cannot pass the auxdata table from the board init code to twl-core like we used to with just legacy platform data. So let's use the omap_device bus hook to patch in the platform data for TWL GPIO until we have sorted out the issues with the TWL GPIOs and device tree bindings. The other option was be to initialize twl core using legacy platform data, which seems like a step backwards as we're moving to device tree only initialization. And we really don't want to add custom configuration functions to the TWL GPIO driver either for this. Signed-off-by: Tony Lindgren <tony@atomide.com>
2013-11-25ARM: OMAP2+: Add quirks support for n8x0Tony Lindgren1-0/+16

2013-11-25ARM: OMAP2+: Add support for board specific auxdata quirksTony Lindgren1-7/+25

2013-11-25ARM: OMAP2+: Fix eMMC on n900 with device treeTony Lindgren1-0/+1
Looks like we need to configure the regulators and use the pdata quirk to make eMMC work with device tree. It seems that mostly vaux3 is used, and only some earlier revisions used vmmc2. This has been tested to work on devices where the system_rev passed by the bootloader has versions 0x0010, 0x2101 and 0x2204.
