2022-04-08dmaengine: sh: Kconfig: Make RZ_DMAC depend on ARCH_RZG2LLad Prabhakar1-1/+1
The DMAC block is identical on Renesas RZ/G2L, RZ/G2UL and RZ/V2L SoC's, so instead of adding dependency for each SoC's add dependency on ARCH_RZG2L. The ARCH_RZG2L config option is already selected by ARCH_R9A07G043, ARCH_R9A07G044 and ARCH_R9A07G054.

2022-03-11dmaengine: sh: Kconfig: Add ARCH_R9A07G054 dependency for RZ_DMAC config optionLad Prabhakar1-3/+3
RZ/V2L DMA block is identical to one found on RZ/G2L SoC. This patch adds ARCH_R9A07G054 dependency for RZ_DMAC config option so that the driver can be enabled on RZ/V2L SoC. While at it, also update config help text.

2018-12-05dmaengine: sh: Remove R-Mobile APE6 supportGeert Uytterhoeven1-10/+1
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.

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.

2015-12-10dmaengine: sh: Remove unused R-Car HPB-DMAC driverGeert Uytterhoeven1-6/+0
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.

2015-04-02dmaengine: usb-dmac: Add Renesas USB DMA Controller (USB-DMAC) driverYoshihiro Shimoda1-0/+9
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.

2015-03-18dmaengine: remove Renesas Audio DMAC peri periKuninori Morimoto1-6/+0
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.

2014-12-23dmaengine: rcar-dmac: Add Renesas R-Car Gen2 DMA Controller (DMAC) driverLaurent Pinchart1-1/+13
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.

This patch adds Kconfig in the drivers/dma/sh. This patch also adds a new config "SH_DMAE_BASE" and the "config SH_DMAE" depends on it. Since some drivers (e.g. sh_mmcif.c) depends on shdma-base.c if CONFIG_DMA_ENGINE=y, the "config SH_DMAE_BASE" is set as "bool".
