dmaengine: sh: Kconfig: Drop ARCH_R7S72100/ARCH_RZG2L dependency

2025-10-16T12:12:59Z

The RZ DMA controller is used across multiple Renesas SoCs, not only RZ/A1 (R7S72100) and RZ/G2L. Limiting the build to these SoCs prevents enabling the driver on newer platforms such as RZ/V2H(P) and RZ/V2N. Replace the ARCH_R7S72100 || ARCH_RZG2L dependency with ARCH_RENESAS so the driver can be built for all Renesas SoCs.

dmaengine: sh: Do not enable SH_DMAE_BASE by default during compile testing

2025-06-26T22:34:19Z

Enabling the compile test should not cause automatic enabling of all drivers. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250404122114.359087-1-krzysztof.kozlowski@linaro.org Signed-off-by: Vinod Koul

dmaengine: sh: rz-dmac: add r7s72100 support

This SoC needs to make getting resets optional. Descriptions are reworded to be more generic. Signed-off-by: Wolfram Sang Reviewed-by: Philipp Zabel Reviewed-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20241007110200.43166-8-wsa+renesas@sang-engineering.com Signed-off-by: Vinod Koul

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
