dmaengine: dw: append MODULE_ALIAS for platform driver

2015-03-30T10:11:45Z

commit a104a45ba7a51b5b4c5e8437020d9d48edf22f89 upstream. The commit 9cade1a46c77 (dma: dw: split driver to library part and platform code) introduced a separate platform driver but missed to add a MODULE_ALIAS("platform:dw_dmac"); to that module. The patch adds this to get driver loaded automatically if platform device is registered.

dmaengine: dw: move PM to suspend_late / resume_early stages

2014-05-07T06:14:06Z

There is no need to use *_noirq version of suspend and resume PM callbacks. The suspend_late / resume_early suit better (it was discussed in [1]) and in future could be used for runtime PM support.

DMA-API: dma: dw_dmac.c: convert to use dma_coerce_mask_and_coherent()

2013-10-31T14:48:51Z

This code sequence: if (!pdev->dev.dma_mask) { pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask; pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32); } bypasses the architectures check on the DMA mask. It can be replaced with dma_coerce_mask_and_coherent(), avoiding the direct initialization of this mask. Signed-off-by: Russell King

dma: dw: append MODULE_DEVICE_TABLE for ACPI case

2013-08-05T04:02:26Z

In rare cases (mostly for the testing purposes) the dw_dmac driver might be compiled as a module as well as the other LPSS device drivers (I2C, SPI, HSUART). When udev handles the event of the devices appearing the dw_dmac module is missing. This patch will fix that. Signed-off-by: Andy Shevchenko Acked-by: Viresh Kumar Signed-off-by: Vinod Koul

dma: dw: split driver to library part and platform code

2013-07-05T06:10:44Z

To simplify the driver development let's split driver to library and platform code parts. It helps us to add PCI driver in future. Signed-off-by: Andy Shevchenko Acked-by: Arnd Bergmann Acked-by: Viresh Kumar [Fixed compile error and few checkpatch issues] Signed-off-by: Vinod Koul
