[PATCH 7/7] ARM: mxs: Add SPI driver for mx233/mx28

Fabio already answered your question. Lemme teach you a few more rules:
1) Do not top post in the email conversation ;-)
2) About DT. You're supposed to include imx28.dtsi in your imx28-yourboard.dts 
file. Then everything that's already defined in the imx28.dtsi will be present 
in your imx28-yourboard.dts . But the key thing is, if you define something 
again, it will override the stuff already defined in the imx28.dtsi file. But 
you don't have to redefine everything, just redefine what you need changed.

Best regards,
Marek Vasut
