[PATCH 1/1] mx27_3ds: Add sound support

[Gaëtan Carlier]

Hi,
I have ported code "Enable sound on mx31_3ds" from Philippe Rétornaz to
MX27 3DS platform on master branch of linux-next (tag next-20120806).
I also applied patch "dma: imx-dma: Fix kernel crash due to missing clock
conversion" of Fabio Estevam which is not yet merged in linux-next.
Thanks to them, everything is working good on MX27 3DS platform except that
sound is played too fast.
Which parameter must be adjusted to have sound playing at normal speed ?
In mc13783 codec driver, imx_add_imx_ssi(), clock configuration in
mach-mx27_3ds file ?

Thanks for your help.
