dmaengine: sh: Use ARCH_RENESAS

2016-02-08T03:18:08Z

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

dmaengine: sh: Remove unused R-Car HPB-DMAC driver

2015-12-10T04:13:33Z

As of commit 4baadb9e05c68962 ("ARM: shmobile: r8a7778: remove obsolete setup code"), the Renesas R-Car HPB-DMAC driver is no longer used. In theory it could still be used on R-Car Gen1 SoCs, but that requires adding DT support to the driver, which is not planned. Remove the driver, it can be resurrected from git history when needed.

dmaengine: usb-dmac: Add Renesas USB DMA Controller (USB-DMAC) driver

2015-04-02T07:27:32Z

This DMAC is Renesas USB high-speed module DMA controller that supports slave transfer. This USB-DMAC has similar register sets with R-Car Gen2 DMAC, but the USB-DMAC has specific registers to control the USB transactions. If this code is added into the rcar-dmac driver, it will become unreadable. So, this driver is independent from the rcar-dmac. And, this USB-DMAC uses virt-dma infrastructure.

dmaengine: remove Renesas Audio DMAC peri peri

2015-03-18T08:27:54Z

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC). And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. Audio DMAC peri peri on DMAEngine is no longer needed. remove it.

dmaengine: rcar-dmac: Add Renesas R-Car Gen2 DMA Controller (DMAC) driver

2014-12-23T09:13:01Z

The DMAC is a general purpose multi-channel DMA controller that supports both slave and memcpy transfers. The driver currently supports the DMAC found in the r8a7790 and r8a7791 SoCs. Support for compatible DMA controllers (such as the audio DMAC) will be added later. Feature-wise, automatic hardware handling of descriptors chains isn't supported yet. LPAE support is implemented.
