Subject: ARM: dts: gose: enable sound DMA support via SRC in device tree
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2cde3b6103678a4f3d2079af744937dfc9c4104;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: gose: enable sound DMA support via SRC in device tree

Enable DMA transfer to/from SRC in r8a7793/gose device tree.

     DMA      DMApp
[MEM] -> [SRC] -> [SSIU] -> [SSI]

     DMA      DMApp
[MEM] <- [SRC] <- [SSIU] <- [SSI]

Current sound driver is supporting
SSI/SRC random connection.
So, this patch is tring
SSI0 -> SRC2
SSI1 <- SRC3

Based on similar work for the r8a7791/koeslch by Kuninori Morimoto.
