Describe THS/CIVM in the R8A77980 device trees. Signed-off-by: Sergei Shtylyov <redacted> --- This patch is against the 'renesas-devel-20181008-v4.19-rc7' tag of Simon Horman's 'renesas.git' repo. Changes in version 2: - renamed the thermal device node label; - renamed the thermal zone nodes; - added the passive trip point in the 1st thermal zone and the passive and critical trip points in the 2nd thermal zone; - changed the "hysteresis" prop in the critical trip point; - removed the empty "cooling-maps" node from the 1st thermal zone. arch/arm64/boot/dts/renesas/r8a77980.dtsi | 53 ++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) Index: renesas/arch/arm64/boot/dts/renesas/r8a77980.dtsi ===================================================================
