serial: pl011: use generic DMA slave configuration if possible

2013-03-12T16:56:09Z

With the new OF DMA binding, it is possible to completely avoid the need for platform_data for configuring a DMA channel. In cases where the platform has already been converted, calling dma_request_slave_channel should get all the necessary information from the device tree. This also adds a binding document specific to the pl011 controller, and extends the generic primecell binding to mention "dmas" and other common properties. Like the patch that converts the dw_dma controller, this is completely untested and is looking for someone to try it out.

dt: add clock binding doc to primecell bindings

2012-07-12T00:58:47Z

Add clock binding information for primecell peripherals. For most, a clock input name of "apb_pclk" is required. Any primecell peripherals which are different will need to be documented separately. Signed-off-by: Rob Herring Signed-off-by: Mike Turquette

drivers/amba: create devices from device tree

2011-06-21T17:02:37Z

Add a function to create amba_devices (i.e. primecell peripherals) from device tree nodes. The device tree scanning is done by the of_platform_populate() function which can call of_amba_device_create based on a match table entry. Nodes with a "arm,primecell-periphid" property can override the h/w peripheral id value. Based on the original work by Jeremy Kerr.
