Re: [alsa-devel] [PATCH 0/7][RFC] ASoC: modern style CPU

Hi Pierre-Louis

Thank you for your feedback

+SND_SOC_DAI_LINK_CCP(aif1,

• SND_SOC_DAI_LINK(SDL_CPU("samsung-i2s.0")),
• SND_SOC_DAI_LINK(SDL_CODEC("wm8994-codec", "wm8994-aif1")),
• SND_SOC_DAI_LINK(SDL_PLATFORM("samsung-i2s.0")));

(snip)

static struct snd_soc_dai_link smdk_dai[] = { { /* Primary DAI i/f */ .name = "WM8994 AIF1", .stream_name = "Pri_Dai",

• .cpu_dai_name = "samsung-i2s.0",
  

• .codec_dai_name = "wm8994-aif1",
  

• .platform_name = "samsung-i2s.0",
  

• .codec_name = "wm8994-codec",
  

  .init = smdk_wm8994_init_paiftx, .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_NB_NF | SND_SOC_DAIFMT_CBM_CFM, .ops = &smdk_ops,

• SND_SOC_LINK_CCP(aif1),
  
  

is this really the new direction? Even the acronyms are not simple, it took me 15mn to figure out that CCP stood for CPU/Codec/Platform and I couldn't figure out what SDL means.

The reason of "CCP" (= CPU/CODEC/PLATFORM) was to avoid long naming. and SDL is acronyms of "Snd soc Dai Link". but yes, it is un-understandable. It should be more understandable (and possibly short) naming.

The multiple repetitions of SND_SOC_DAI_LINK is also misleading, it's just a property of the *same* dailink that you handle.

it is needed to handle both single/multi CPU/Codec/Platform. But yes, it has naming issue.

I am even more nervous since we have a need to explicitly some cpu and codec dai names depending on quirks, with the additional abstraction it'll become plain unreadable - or we need new helpers.

Hmm, OK. I will reconsider about macro. I'm happy if you can review it again.

Thank you for your help !!
