[PATCH 0/2] CONFIG_OF vs DMA_OF

[PATCH 0/2] CONFIG_OF vs DMA_OF

[Kuninori Morimoto]

Hi Vinod, Mark

Current OF base DMAEngine API will be compiled if .config has
CONFIG_DMA_OF. but of-dma.h based on CONFIG_OF instead of CONFIG_DMA_OF.
These patches tidyup this issue.

Please check 1) patch carefully, since DMAEngine API has many dependency
to other drivers.

> Mark

I think 2) patch is based on 1). Please check it

Kuninori Morimoto (2):
      1) dmaengine: OF DMAEngine API based on CONFIG_DMA_OF instead of CONFIG_OF
      2) ASoC: rsnd: SND_SOC_RCAR doesn't depend on DMA_OF

[PATCH 1/2] dmaengine: OF DMAEngine API based on CONFIG_DMA_OF instead of CONFIG_OF

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

5fa422c ("dmaengine: move drivers/of/dma.c -> drivers/dma/of-dma.c")
moved OF base DMAEngine code to of-dma.c, then it based on CONFIG_DMA_OF.
But, OF base DMAEngine API on of_dma.h still based on CONFIG_OF now.
So, current kernel can't find OF base DMAEngine API if .config has CONFIG_OF,
but not have CONFIG_DMA_OF. This patch tidyup it.

[PATCH 2/2] ASoC: rsnd: SND_SOC_RCAR doesn't depend on DMA_OF

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

8616774("ASoC: rnsd: fix build regression without CONFIG_OF")
added "depends on DMA_OF" in SND_SOC_RCAR to avoid compile error of

    sound/built-in.o: In function `rsnd_dma_request_channel':
    :(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel'

But, it was OF base DMAEngine API definition issue, not SND_SOC_RCAR
issue. This patch remove DMA_OF dependence.

I did a quick build with arm config, but didn't see any failures. But still
am worried about random config and other builds may find.

So I think it would be safer to merge this patch after merge window so that
we have ample time to fix any issue
