Signed-off-by: Martin Sperl Reviewed-by: Eric Anholt Acked-by: Stefan Wahren Changelog: V1 -> V5: generic settings is shared in bcm283x.dtsi, but disabled moved the compatible string to the SOC specific dtsi for arm and arm64 V5 -> V6: fix remove 0x prefix from thermal at 0x7e212000 Note: there is no arm/boot/dts/bcm2837.dtsi as of now, so the 32-bit rpi3 dt is not modified. --- arch/arm/boot/dts/bcm2835.dtsi | 6 ++++++ arch/arm/boot/dts/bcm2836.dtsi | 6 ++++++ arch/arm/boot/dts/bcm283x.dtsi | 7 +++++++ 3 files changed, 19 insertions(+) diff --git a/arch/arm/boot/dts/bcm2835.dtsi b/arch/arm/boot/dts/bcm2835.dtsi index a78759e..0890d97 100644 --- a/arch/arm/boot/dts/bcm2835.dtsi +++ b/arch/arm/boot/dts/bcm2835.dtsi @@ -23,3 +23,9 @@ }; }; }; + +/* enable thermal sensor with the correct compatible property set */ +&thermal { + compatible = "brcm,bcm2835-thermal"; + status = "okay"; +}; diff --git a/arch/arm/boot/dts/bcm2836.dtsi b/arch/arm/boot/dts/bcm2836.dtsi index 9d0651d..519a44f 100644 --- a/arch/arm/boot/dts/bcm2836.dtsi +++ b/arch/arm/boot/dts/bcm2836.dtsi @@ -76,3 +76,9 @@ interrupt-parent = <&local_intc>; interrupts = <8>; }; + +/* enable thermal sensor with the correct compatible property set */ +&thermal { + compatible = "brcm,bcm2836-thermal"; + status = "okay"; +}; diff --git a/arch/arm/boot/dts/bcm283x.dtsi b/arch/arm/boot/dts/bcm283x.dtsi index 46d46d8..f794a18 100644 --- a/arch/arm/boot/dts/bcm283x.dtsi +++ b/arch/arm/boot/dts/bcm283x.dtsi @@ -187,6 +187,13 @@ interrupts = <2 14>; /* pwa1 */ }; + thermal: thermal at 7e212000 { + compatible = "brcm,bcm2835-thermal"; + reg = <0x7e212000 0x8>; + clocks = <&clocks BCM2835_CLOCK_TSENS>; + status = "disabled"; + }; + aux: aux at 0x7e215000 { compatible = "brcm,bcm2835-aux"; #clock-cells = <1>; -- 2.1.4
