How would you comment the following code, v3.10-rc7:

arch/arm/boot/dts/dbx5x0.dtsi, line 375
375                                  ab8500-gpadc {
376                                          compatible =
"stericsson,ab8500-gpadc";
377                                          interrupts = <32
IRQ_TYPE_LEVEL_HIGH
arch/arm/boot/dts/dbx5x0.dtsi:                          ab8500-gpadc {
arch/arm/boot/dts/dbx5x0.dtsi:
compatible = "stericsson,ab8500-gpadc";
arch/arm/boot/dts/dbx5x0.dtsi:
vddadc-supply = <&ab8500_ldo_tvout_reg>;


arch/arm/boot/dts/sama5d3.dtsi:                 tsadcc: tsadcc@f8018000 {
arch/arm/boot/dts/sama5d3.dtsi:                         compatible =
"atmel,at91sam9x5-tsadcc";
arch/arm/boot/dts/sama5d3.dtsi:
atmel,tsadcc_clock = <300000>;

arch/arm/boot/dts/am33xx.dtsi:          tscadc: tscadc@44e0d000 {
arch/arm/boot/dts/am33xx.dtsi:                  compatible = "ti,am3359-tscadc";
arch/arm/boot/dts/am33xx.dtsi:                  ti,hwmods = "adc_tsc";
arch/arm/boot/dts/am33xx.dtsi:                  am335x_adc: adc {
arch/arm/boot/dts/am33xx.dtsi:                          compatible =
