As the series is fairly long, we will see if there is a need to resend it or not. > + dma-names = "fifo0", "fifo1"; > + status = "disabled"; > + > + mag { > + compatible = "ti,am4372-mag"; > + }; > + > + adc { > + #io-channel-cells = <1>; > + compatible ="ti,am4372-adc"; > + }; > + }; > }; > > target-module@80000 { /* 0x48380000, ap 123 42.0 */ > diff --git a/arch/arm/boot/dts/am43xx-clocks.dtsi b/arch/arm/boot/dts/am43xx-clocks.dtsi > index c726cd8dbdf1..59b1f592a743 100644 > --- a/arch/arm/boot/dts/am43xx-clocks.dtsi > +++ b/arch/arm/boot/dts/am43xx-clocks.dtsi > @@ -444,6 +444,13 @@ wdt1_fck: wdt1_fck@422c { > reg = <0x422c>; > }; > > + adc_mag_fck: adc_mag_fck@424c { > + #clock-cells = <0>; > + compatible = "ti,mux-clock"; > + clocks = <&sys_clkin_ck>, <&dpll_per_m2_ck>; > + reg = <0x424c>; > + }; > + > l3_gclk: l3_gclk { > #clock-cells = <0>; > compatible = "fixed-factor-clock"; Thanks, Miquèl

This hardware module is close to the am33xx ADC module but instead of featuring a touchscreen it has a magnetic reader capability.
