Add i.MX8QXP CPU thermal zone support. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> --- Changes since V10: - remove property "imx,sensor-resource-id" and put HW resource ID inside each thermal-sensors' phandle argument. --- arch/arm64/boot/dts/freescale/imx8qxp.dtsi | 33 ++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+)
