2013-07-05dmaengine: at_hdmac: remove unsuded atc_cleanup_descriptors()Nicolas Ferre1-31/+0
Since patch 7c407d3e54dcc0c79119553c8d5ef176c1d5bc3a (DMA: AT91: Get residual bytes in dma buffer), the function atc_cleanup_descriptors() is not used anymore. We remove it to prevent warnings.

2013-07-05dmaengine: at_hdmac: add FIFO configuration parameter to DMA DT bindingLudovic Desroches1-4/+21
For most devices the FIFO configuration is the same i.e. when half FIFO size is available/filled, a source/destination request is serviced. But USART devices have to do it when there is enough space/data available to perform a single AHB access so the ASAP configuration.

2013-07-05dma: Add a jz4740 dmaengine driverLars-Peter Clausen3-0/+440
This patch adds dmaengine support for the JZ4740 DMA controller. For now the driver will be a wrapper around the custom JZ4740 DMA API. Once all users of the custom JZ4740 DMA API have been converted to the dmaengine API the custom API will be removed and direct hardware access will be added to the dmaengine driver.

2013-07-05dmaengine: PL08x: Avoid collisions with get_signal() macroMark Brown1-4/+4
As pointed out by Arnd Bergmann there is a get_signal macro definied in linux/signal.h which can conflict with the platform data callback function of the same name leading to confusing errors from the compiler (especially if signal.h manages to get pulled into the driver itself due to header dependencies). Avoid such errors by renaming get_signal and put_signal in the platform data to get_xfer_signal and put_xfer_signal.

2013-07-05dma: pl330: rip out broken, redundant ID probingWill Deacon1-24/+3
The PL330 driver probes the peripheral and primecell IDs of the device to make sure that it is indeed an AMBA PL330. However, it does this by making byte accesses to a device mapping of the word-aligned ID registers, which is either UNPREDICTABLE or generates an alignment fault (depending on the presence of the virtualisation extensions). Rather than fix this code, we can actually rip most of it out and let the AMBA bus driver correctly do the probing for us.

Lock scenario: Channel 1 was allocated and prepared as slave_sg, used and freed. Now preparation of cyclic dma on channel 1 will fail with err "DMA configuration conflict" because tdc->isr_handler still setted to handle_once_dma_done. This happens because tegra_dma_abort_all() won't be called on channel freeing if pending list is empty and channel not busy. We need to clear isr_handler on channel freeing to avoid locking.

Add support for returning the residue for current transfer cookie by reading the transfered buffer size(BTSIZE) in CTRLA register. For a single buffer cookie, the descriptor length minus BTSIZE can get the residue. For a lli cookie, remain_desc will record remain descriptor length when last descriptor finish, the remain_desc minus BTSIZE can get the current residue. If the cookie has completed successfully, the residue will be zero. If the cookie is in progress, it will be the number of bytes yet to be transferred. If get residue error, the cookie will be turn into error status. Check dma fifo to see if data remain, let issue pending finish remain work if there is.

2013-06-12dma: of: Remove check on always true conditionLars-Peter Clausen1-13/+1
Both of_dma_nbcells field of the of_dma_controller and the args_count field of the dma_spec are initialized by parsing the #dma-cells attribute of their device tree node. So if the device tree nodes of a DMA controller and the dma_spec match this means that of_dma_nbcells and args_count will also match. So the second test in the of_dma_find_controller loop is redundant because given the first test yields true the second test will also yield true. So we can safely remove the test whether of_dma_nbcells matches args_count. Since this was the last user of the of_dma_nbcells field we can remove it altogether.

There is no sensible reason why #dma-cells shouldn't be allowed to be 0. It is completely up to the DMA controller how many additional parameters, besides the phandle, it needs to identify a channel. E.g. for DMA controller with only one channel or for DMA controllers which don't have a restriction on which channel can be used for which peripheral it completely legitimate to not require any additional parameters.

2013-06-07ACPI / PM: Do not execute _PS0 for devices without _PSC during initializationRafael J. Wysocki1-4/+6
Commit b378549 (ACPI / PM: Do not power manage devices in unknown initial states) added code to force devices without _PSC, but having _PS0 defined in the ACPI namespace, into ACPI power state D0 by executing _PS0 for them. That turned out to break Toshiba P870-303, however, so revert that code.

2013-06-06USB: option,zte_ev: move most ZTE CDMA devices to zte_evDan Williams2-26/+22
Per some ZTE Linux drivers I found for the AC2716, the following patch moves most ZTE CDMA devices from option to zte_ev. The blacklist stuff that option does is not required with zte_ev, because it doesn't implement any of the send_setup hooks which the blacklist suppressed. I did not move the 2718 over because I could not find any ZTE Linux drivers for that device, nor even any Windows drivers.
