* dmaengine: dw: Remove AVR32 bits from the driverAndy Shevchenko2017-05-151-21/+0
| | | | | | | | | AVR32 is gone. Now it's time to clean up the driver by removing leftovers that was used by AVR32 related code. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* dmaengine: dw: register IRQ and DMA pool with instance IDAndy Shevchenko2017-01-251-0/+2
| | | | | | | | | | | It is really useful not only for debugging to have an IRQ line and DMA pool labeled with driver and its instance ID. Do this for DesignWare DMA driver. All current users of this IP would be enhanced later on. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
* dmaengine: dw: provide probe(), remove() stubs for usersAndy Shevchenko2016-08-311-0/+5
| | | | | | | | | | | Some users consider DMA optional, thus when driver is not compiled we shouldn't prevent compilation of the users. Add stubs for dw_dma_probe() and dw_dma_remove().

* dmaengine: dw: pass platform data via struct dw_dma_chipAndy Shevchenko2016-05-021-1/+4
| | | | | | | | | | | We pass struct dw_dma_chip to dw_dma_probe() anyway, thus we may use it to pass a platform data as well. While here, constify the source of the platform data.

* dmaengine: dw: export probe()/remove() and Co to usersAndy Shevchenko2014-10-151-0/+27
| | | | | | | | | | | | | The driver library functions can be used directly by the compound devices such as ADSP or serial driver where DesignWare DMA IP is privately attached to the main hardware. Instead of creating a new platform device leaf they may call dw_dma_probe() with given struct dw_dma_chip directly and make sure that the main device is DMA capable.

* dmaengine: dw: split dma-dw.h to platform and private partsAndy Shevchenko2014-10-151-0/+37
The introduced include/linux/dma/dw.h is going to contain the private extensions and structures which are shared for dw_dmac users in the kernel. Meanwhile include/linux/platform_data/dma-dw.h keeps only platform related data types and definitions.
