Subject: Re: [PATCH v2] soc: mediatek: add SMC fid table for SIP interface

Hi Matthias,


I will upstream mt6779 sound card driver on Mark's ASoC repo:
http://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

But it is still under internal reviewing and not yet upstream.
So, I think that this patch could be upstream first.

Maybe, other mtk sip clients can use this header and add their's
specific MTSK_SIP_* ID.

Regards,
Eason
