spi on mpc82xx

spi on mpc82xx

[Thomas Arvanitis]

Hi,

I was wondering what is the status for supporting spi devices with 2.6
on an mpc82xx device (I use an mpc8275). I checked and the kernel from
kernel.org does not include anything. Is there an spi bus
infrastructure (like i2c) coming any time soon, where one can add
support for specific chips, and then write a driver on top of that?
Or a plan for these things?

I found a patch for something like that, by Grant Likely, but I don't
know whether I should go that way.

I want to write a driver for controlling the micrel ks8995 ethernet
switch through spi. Should I just go for a self contained driver?

Thanks for you help,
-Thomas.

There has be some patches on the lkml list for the creation of a SPI  
layer similar to I2C.  I'm not sure what the latest status is.  I'd  
google search for SPI on lkml.

Once something like that gets in I'm sure someone will get around to  
contributing a SPI driver for the 82xx line of processors.
