[PATCH 00/30] ARM: dts: r8a779[0-4]: Reference both DMA controllers

[Niklas Söderlund]

Hi,

R-Car Gen2 have two DMA controllers, which are equivalent. However DMA
slaves were tied only to a single DMA controller in .dtsi. This series
add references to to both DMA controllers for all nodes that previously
only referenced one of them. It also adds dma references to the SDHI
nodes for r8a7794 which according to the datasheet should work but I
have not access to HW to verify.

Tested on Koelsch (r8a7791) by altering the compatible value of either
dmac0 or dmac1 and verifying that the DMA slaves pick the DMA controller
that is instantiated.

[PATCH 01/30] ARM: dts: r8a7790: Reference both DMA controllers in SCIFA nodes

[Niklas Söderlund]

R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.

[PATCH 09/30] ARM: dts: r8a7790: Reference both DMA controllers in MMCIF nodes

[Niklas Söderlund]

R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.

[PATCH 16/30] ARM: dts: r8a7791: Reference both DMA controllers in IIC nodes

[Niklas Söderlund]

R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.

[PATCH 23/30] ARM: dts: r8a7793: Reference both DMA controllers in QSPI node

[Niklas Söderlund]

R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.

This one has the wrong subject: QSPI vs. MMCIF.

Thanks for noticing, would have been embarrassing for me.

Thanks for your series!

If you fix the subject of patch 30:
Acked-by: Geert Uytterhoeven <geert+renesas@glider.be>

I guess this is against v4.5-rc7? It doesn't apply against
renesas-devel-20160308-v4.5-rc7.
Unfortunately you'll have to rebase against Simon's tree, and add scif2
on r8a7790, and i2c[6-8] on r8a7793.

Hint for the other reviewers: use the --color-words option of git diff/show.

Thanks for your review and that you found my error in the subject.

I will rebase and update the relevant patches to include the additions 
to r8a7790 and r8a7793.

If its not too much bother could you provide a git branch as well as
patches posted to the mailing list.  For larger series that is helpful to me.
