2011-12-26usb: ohci-s5p: Fixed USB OHCI shutdown and suspend hang issuePankaj
It has been observed that during system reboot or suspend/resume system hangs. Further debugging showed that during shutdown/suspend call OHCI driver was not able to access any of OHCI registers failing which it was hanging. As after observing idle condition over the bus OHCI host core controller (HW) is turning off 12 and 48MHz clocks internally, and since during shutdown/suspend these clocks are OFF driver is not able to access any of OHCI registers. So as per guidlines given on data-sheet and Synopsys website, we need to manually enable to clocks for completion of ohci shutdown/suspend function.

2011-12-26ARM: EXYNOS: Add a alias for pdma clocksThomas Abraham
PDMA controllers when instantiated from device tree are registered using amba_device_register(). The registration process enables clock to the controllers to read the peripheral id of the PDMA amba device. In case of Exynos4, the clocks to the PDMA controllers are named as 'dma' but amba_device_register() looks up the clock using the name 'apb_pclk'. Hence, alias clocks with name 'apb_pclk' clock are created for clocks with name 'dma'. Signed-off-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

For images that include both dt and non-dt platforms, an addditional check is added to ensure that static amba device registrations is applicable to only non-dt platforms.

2011-12-26ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappersThomas Abraham
A new dma request id 'DMACH_DT_PROP' is introduced for client drivers requesting a dma channel. This request indicates that a device tree node property represting the dma channel is available in 'struct samsung_dma_info'. The dma channel request wrapper uses the node property value as the value for the filter parameter.

2011-12-26DMA: PL330: Add device tree supportThomas Abraham
For PL330 dma controllers instantiated from device tree, the channel lookup is based on phandle of the dma controller and dma request id specified by the client node. During probe, the private data of each channel of the controller is set to point to the device node of the dma controller. The 'chan_id' of the each channel is used as the dma request id. Client driver requesting dma channels specify the phandle of the dma controller and the request id. The pl330 filter function converts the phandle to the device node pointer and matches that with channel's private data. If a match is found, the request id from the client node and the 'chan_id' of the channel is matched. A channel is found if both the values match.

2011-12-26DMA: PL330: Infer transfer direction from transfer request instead of ↵Thomas Abraham
platform data The transfer direction for a channel can be inferred from the transfer request and the need for specifying transfer direction in platfrom data can be eliminated. So the structure definition 'struct dma_pl330_peri' is no longer required. The channel's private data is set to point to a channel id specified in the platform data (instead of an instance of type 'struct dma_pl330_peri'). The filter function is correspondingly modified to match the channel id. With the 'struct dma_pl330_peri' removed from platform data, the dma controller transfer capabilities cannot be inferred any more. Hence, the dma controller capabilities is specified using platform data.

2011-12-26DMA: PL330: move filter function into driverThomas Abraham
The dma channel selection filter function is moved from plat-samsung into the pl330 driver. In additon to that, a check is added in the filter function to ensure that the channel on which the filter has been invoked is pl330 channel instance (and avoid any incorrect access of chan->private in a system with multiple types of DMA drivers).
