dmaengine: Kconfig: Update description for RCAR_DMAC config

2020-09-11T12:18:28Z

rcar-dmac driver is used on Renesas R-Car Gen{2,3} and Renesas RZ/G{1,2} SoC's, update the same to reflect the description for RCAR_DMAC config.

SUDMAC driver was introduced in v3.10 but was never integrated for use by any platform. As it is unused remove it. Signed-off-by: Simon Horman Acked-by: Yoshihiro Shimoda Signed-off-by: Vinod Koul

dmaengine: sh: Remove R-Mobile APE6 support

2018-12-05T07:31:54Z

Renesas R-Mobile APE6 support is currently unused: - DMA slaves were never enabled in r8a73a4.dtsi, - The driver relies on legacy filter matching and describing all slaves and MID/RIDs in a table, unlike modern DMA engine drivers for similar hardware like rcar-dmac, - The driver doesn't seem to work well. Remove the driver, it can be resurrected from git history when needed. As this was the last user of SH_DMAE_BASE on Renesas ARM SoCs, the sh-dma-engine driver core is now used on SuperH only. Note that the DT bindings are still present, as r8a73a4.dtsi uses them. Signed-off-by: Geert Uytterhoeven Reviewed-by: Ulrich Hecht Reviewed-by: Simon Horman Signed-off-by: Vinod Koul

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.
