Russell, thanks for your reply :-)

Absolutely, you're right. I missed.

Unfortunately, as I know, there is no suitable branch for it and me in

Hmm...happened error when merged but I don't know how can solve that :-(

IMHO, your first option is better to me but it depends on Takashi...hehe...
Anyway Thanks and Happy New year!


Takashi, as Russell's first option, could you please make some branch which

Of course, I know you need rebase you tree for it...so sorry for bothering.

    ARM: Samsung: Define common audio-dma device

    The ASoC uses common DMA driver for Audio devices. So it makes
    sense to a common audio-dma device shared across all platforms.

    ASoC: Samsung: Rename DMA device

    Some Samsung SoCs have a PCM(DSP) controller. So the name
    s3c24xx-pcm-audio for DMA driver is not very appropraite.
    This patch moves :-
        s3c24xx-pcm-audio -> samsung-audio
