Re: [PATCH] powerpc: add fsl, fifo-depth property to Freescale SSI device nodes

The Freescale Serial Synchronous Interface (SSI) is an audio device

some Freescale SOCs.  Various implementations of the SSI have a  
different
transmit and receive FIFO depth, but are otherwise identical.  To  
support
these variations, add a new property fsl,fifo-depth to the SSI node  
that
specifies the depth of the FIFOs.

Also update the MPC8610 HPCD device tree with this property.

Updates to the SSI audio driver will come later.  Currently, this  
driver
supports only one Freescale SOC, and so it's hard-coded to use the  
value 8.
If/when this driver is updated to support other SOCs (e.g. the i.MX  
parts
that have a FIFO depth of 15), the driver will check for this  
property.  I
just want to get this DTS change in now.
