"timer" would be a better node name than "gpt", and the device type should be
left out entirely.  As others pointed out, compatible should be
"fsl,mpc5200b-gpt", "fsl,mpc5200-gpt".

fsl,has-wdt

This doesn't actually implement the OF rtc interface...

What is mscan?

This is not a standard device type.

dma-controller should be the node name, and device_type should be omitted.

Should be local-mac-address.  
And yes, hardcoding a mac address is bad.  Don't do it. :-)

What is cell-index?  The fsl-i2c driver doesn't use it AFAICT.

No device type.

This device is compatible with every CPLD that has ever existed?  Wow! :-)
