[alsa-devel] Lockups reading from i.MX51 SSI registers

Hi,

I'm trying to use -next to test AC'97 register I/O on an i.MX51 board but I'm seeing the CPU hang during probe at:

lreg = (reg & 0x7f) << 12 ; writel(lreg, base + SSI_SACADD);

in imx_ssi_ac97_read(). I'm somewhat suspicious this might be because the IP block isn't clocked properly, I do notice the recent conversion to the clock API which looks rather involved but it's possible something else broke. Does anyone have any bright ideas what might be going on here? The board doesn't have the reste functions defined so this is the first interaction with the hardware block AFAICT.

Thanks, Mark
