Re: [alsa-devel] [PATCH 1/3] ASoC: Add a new imx-ssi sound driver

2009/11/30 javier Martin javier.martin@vista-silicon.com

Dear Sascha, in "imx_ssi_set_dai_fmt()" callback you should add something like:

/* sync */
scr |= SSI_SCR_SYN;

This would enable SSI working in SYN mode which means that RX and TX sections will share same frame and bit clocks. Right now I can't imagine a situation where this is not desirable. Moreover, if I don't add SYN mode I cannot get it working in my i.mx27 based board with an wm8974.

Well, after a chat with Mark it seems that it is not so uncommon that RX and TX sections have different clocks. So you could add a flag in the platform data similar to the one that switches between FIQ and DMA so that people can choose if they want the feature or not.

Thank you.
