All that information is in the "disabled" node contained in .dtsi file.
+ msp0: msp@80123000 {
+ compatible = "stericsson,ux500-msp-i2s";
+ reg = <0x80123000 0x1000>;
+ interrupts = <0 31 0x4>;
+ v-ape-supply = <&db8500_vape_reg>;
+ status = "disabled";
Then this patch "enable"s it (as the title suggests). :)
