Pull "dt-bindings: Updates for v4.15-rc1" from Thierry Reding: This contains the addition of a clock alias which will be used to fix the implementation of the SOR1 clock. Also included are the bindings for the Tegra186 BPMP thermal driver, a prerequisite for both the driver and device tree changes. * tag 'tegra-for-4.15-dt-bindings' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: Add bindings for nvidia,tegra186-bpmp-thermal dt-bindings: clock: tegra: Add sor1_out clock

+NVIDIA Tegra186 BPMP thermal sensor
+
+In Tegra186, the BPMP (Boot and Power Management Processor) implements an
+interface that is used to read system temperatures, including CPU cluster
+and GPU temperatures. This binding describes the thermal sensor that is
+exposed by BPMP.
+
+The BPMP thermal node must be located directly inside the main BPMP node. See
+../firmware/nvidia,tegra186-bpmp.txt for details of the BPMP binding.
+
+This node represents a thermal sensor. See thermal.txt for details of the
+core thermal binding.
+
+Required properties:
+- compatible:
+ Array of strings.
+ One of:
+ - "nvidia,tegra186-bpmp-thermal".
+- #thermal-sensor-cells: Cell for sensor index.
+ Single-cell integer.
+ Must be <1>.
+
+Example:
+
+bpmp {
+ ...
+
+ bpmp_thermal: thermal {
+ compatible = "nvidia,tegra186-bpmp-thermal";
+ #thermal-sensor-cells = <1>;
+ };
+};
