Since the DMA device doesn't show up as PCIe device, a virtual bus called mic bus is created and virtual devices are added on that bus to follow device model.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VIDEO_TIMBERDALE selects TIMB_DMA which itself depends on MFD_TIMBERDALE, so VIDEO_TIMBERDALE should either select or depend on MFD_TIMBERDALE as well. I chose to make it depend on it because I think it makes more sense and it is consistent with what other options are doing. Adding a "|| HAS_IOMEM" to the TIMB_DMA dependencies silenced the kconfig warning about unmet direct dependencies but it was wrong: without MFD_TIMBERDALE, TIMB_DMA is useless as the driver has no device to bind to.

Each BAM DMA device is associated with a specific on-chip peripheral. Each channel provides a uni-directional data transfer engine that is capable of transferring data between the peripheral and system memory (System mode), or between two peripherals (BAM2BAM). The initial release of this driver only supports slave transfers between peripherals and system memory.

Option 2 adds checks for behavior that is already documented as broken when using get_user_pages(). At a minimum a debug mode is warranted to catch and flag these violations of the dma-api vs get_user_pages(). Thanks to David for his reproducer.
