This patch series is based on - renesas-drivers.git / renesas-drivers-2019-08-13-v5.3-rc4 tag - and the following patch series: https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=165881 The commit e2d896c08ca3 ("Documentation: bindings: dma: Add binding for dma-channel-mask") adds the generic property and R-Car also has such use cases so that I made this patch series. Before adding the property support, I made a clean-up patch as the patch 1/2.
