Ls1088a has 2 thermal sensors, core cluster and SoC platform. Core cluster sensor is used to monitor the temperature of core and SoC platform is for platform. The current dts only support the first sensor. This patch adds the second sensor node to dts to enable it. Signed-off-by: Yuantian Tang <andy.tang@nxp.com> --- v3: - use more descriptive name for each zone v2: - Add more information about sensors to description PS: In order to keep consistency to the first thermal-zone node, there will be "WARNING: line over 80 characters" warnings. arch/arm64/boot/dts/freescale/fsl-ls1088a.dtsi | 43 +++++++++++++++++++++-- 1 files changed, 39 insertions(+), 4 deletions(-)
