This patch adds wm8994 codec node on i2c bus1 and the required regulator supplies and properties on smdk5420 board.
This isn't a device tree patch for WM8994, it's a patch for the SMDK5420.
- vdd: fixed-regulator@0 {
compatible = "regulator-fixed";regulator-name = "vdd-supply";
These names look wrong - they should reflect the names in the schematic as they're for human comprehensibility. This may just be a case of dropping the -supply.
wm8994: wm8994@1a {compatible = "wlf,wm8994";reg = <0x1a>;gpio-controller;#gpio-cells = <2>;AVDD2-supply = <&vdd>;CPVDD-supply = <&vdd>;DBVDD-supply = <&dbvdd>;SPKVDD1-supply = <&spkvdd>;SPKVDD2-supply = <&spkvdd>;};
It would be helpful to also add a clock binding (I posted a binding documentation update the other day, it's in my tree now) but it's not essential and I suspect it needs some work on the clock driver side still.
