2013-02-02cpufreq / highbank: add support for highbank cpufreqMark Langsdorf1-0/+10
Highbank processors depend on the external ECME to perform voltage management based on a requested frequency. Communication between the A9 cores and the ECME happens over the pl320 IPC channel.

2013-01-08ARM: dts: fix highbank cpu mpidr valuesRob Herring1-8/+8
With the addition of commit a0ae0240 (ARM: kernel: add device tree init map function), the cpu reg values must match the cpu mpidr register or we'll get warnings. For some reason, the CLUSTERID on highbank is 9, so the reg value needs to be 0x90n to quiet the warnings.

2013-01-08ARM: dts: add device_type prop to cpu nodes on Calxeda platformsRob Herring1-0/+4

2012-10-03Merge branch 'for-v3.7' of ↵Linus Torvalds1-0/+1
git://git.linaro.org/people/mszyprowski/linux-dma-mapping Pull CMA and DMA-mapping updates from Marek Szyprowski: "This time the pull request is rather small, because the further redesign patches were not ready on time. This pull request consists of the patches which extend ARM DMA-mapping subsystem with support for CPU coherent (ACP) DMA busses. The first client of the new version is HighBank SATA driver. The second part of the pull request includes various cleanup for both CMA common code and ARM DMA-mapping subsystem." Fix up trivial add-add conflict due to the "dma-coherent" DT property being added next to the "calxeda,port-phys" property for the Calxeda AHCI controller. * 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: ARM: dma-mapping: Remove unsed var at arm_coherent_iommu_unmap_page ARM: highbank: add coherent DMA setup ARM: kill off arch_is_coherent ARM: add coherent iommu dma ops ARM: add coherent dma ops ARM: dma-mapping: Refrain noisy console message ARM: dma-mapping: Small logical clean up drivers: dma-contiguous: refactor dma_alloc_from_contiguous()
2012-10-02ARM: highbank: add coherent DMA setupRob Herring1-0/+1
Some highbank DMA masters can support coherent (ACP) or non-coherent DMA. This sets up dma_map_ops for masters which are configured for coherent DMA. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
2012-09-13ata: add platform driver for Calxeda AHCI controllerMark Langsdorf1-0/+17
Calxeda highbank SATA phy has intermittent problems bringing up a link with Gen3 drives. Retrying the phy hard reset can work-around this issue, but each reset also disables spread spectrum support. The reset function also needs to reprogram the phy to enable spread spectrum support. Create a new driver based on ahci_platform to support the Calxeda Highbank SATA controller.

2012-04-15ARM: dts: remove blank interrupt-parent propertiesRob Herring1-1/+0
These were incorrectly introduced and can cause problems for of_irq_init. The correct way to define a root controller is no interrupt-parent set at all or the interrupt-parent is set to the root controller itself when inherited from a parent node.
