2014-03-12ARM: dts: omap3-tobi: Use include file omap-gpmc-smsc9221Florian Vaussard
Use the timings provided by omap-gpmc-smsc9221. This does not change the timings, but it avoids code duplication. Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-03-12ARM: dts: omap: Add common file for SMSC9221Florian Vaussard
Some devices (SMSC9217, SMSC9218 and SMSC9221 at least) have better timings, allowing a higher transfer speed. Create a common file with these timings.

2014-03-12ARM: dts: overo: reorganize include filesFlorian Vaussard
Currently, overo-related include files are organized as follow: omap3-overo.dtsi | | omap34xx.dtsi omap3-overo-tobi-common.dtsi omap36xx.dtsi | | | | --------------- --------------- | | omap3-overo-tobi.dts omap3-overo-storm-tobi.dts This is unpractical when one has to deal with SoC-specific pinmux belonging to the omap3_pmx_core2 (defined in omap34xx/omap36xx), for pins related to the processor board. With the current hierarchy, such pinmux has to be defined in the expansion board's .dts, which is not logical. This patches reorganizes the files to add (yet another) abstraction layer between the processor and the expansion boards. omap34xx.dtsi omap3-overo-base.dtsi omap36xx.dtsi | | | | --------------- --------------- | | omap3-overo.dtsi omap3-overo-storm.dtsi | | -------- ------ | omap3-overo-tobi-common.dtsi | | | | | --------------- --------------- | | omap3-overo-tobi.dts omap3-overo-storm-tobi.dts Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Tony Lindgren <tony@atomide.com>

2014-03-12ARM: OMAP2+: use pdata quirks for iommu reset linesSuman Anna
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).

2014-03-12ARM: OMAP2+: change the ISP device archdata MMU name for DTSuman Anna
The IOMMU DT adaptation support uses the device name instead of an iommu object name. Fixup the ISP device archdata MMU name at runtime if using DT-boot. This allows the OMAP3 camera to be functional in both legacy and DT boots. The iommu object names should eventually vanish when all the IOMMU users have been converted to DT nodes.

2014-03-12ARM: OMAP3: fix iva mmu programming issuesSuman Anna
The IVA MMU is not functional when used through the hwmod and omap_device layers. Add fixes to clockdomain and hwmod data to have it functional. The hwmod changes are needed to enable the clock, and the SWSUP change is needed to wakeup the domain because the power domain is programmed to be in RET, and there is no automatic power domain switching to ON.

CONFIG_OMAP_IOMMU_IVA2 was defined originally to avoid conflicting usage by tidspbridge and other iommu users. The same can be achieved by marking the DT node disabled, so remove this obsolete flag and the corresponding hwmod data can be enabled.

2014-03-12ARM: at91: prepare sam9 dt boards transition to common clkBoris BREZILLON
This patch prepare the transition to common clk for sam9 dt boards by replacing the timer init callback. Clocks registration cannot be done in early init callback (as formerly done by the old clk implementation) because it requires dynamic allocation which is not ready yet during early init. In the other hand, at91 clocks must be registered before at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver request the master clk (mck). A new function (at91sam9_dt_timer_init) is created to fullfil these needs. This function registers all at91 clks using the dt definition before calling the PIT init function. The device tree clock registration is enabled only if common clk is selected. Else the old clk registration is been done during at91_dt_initialize call.

2014-03-12cpufreq: SPEAr: Instantiate as platform_driverViresh Kumar
As multiplatform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when SPEAr cpufreq driver is enabled on a kernel booted on a non-SPEAr board, we will get following boot time error: spear_cpufreq: Invalid cpufreq_tbl To eliminate this undesired the effect, the patch changes SPEAr driver to have it instantiated as a platform_driver. Then it will only run on platforms that create the platform_device "spear-cpufreq". This patch also creates platform node for SPEAr13xx boards.
