dmaengine: sh: Kconfig: Make RZ_DMAC depend on ARCH_RZG2L

2022-04-08T17:52:00Z

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.

dmaengine: sh: Kconfig: Add ARCH_R9A07G054 dependency for RZ_DMAC config option

2022-03-11T07:04:05Z

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.

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.
