+NVIDIA Tegra Boot and Power Management Processor (BPMP)
+
+The BPMP is a specific processor in Tegra chip, which is designed for
+booting process handling and offloading the power management, clock
+management, and reset control tasks from the CPU. The binding document
+defines the resources that would be used by the BPMP firmware driver,
+which can create the interprocessor communication (IPC) between the CPU
+and BPMP.
+
+Required properties:
+- name : Should be bpmp
+- compatible
+ Array of strings
+ One of:
+ - "nvidia,tegra186-bpmp"
+- mboxes : The phandle of mailbox controller and the mailbox specifier.
+- shmem : List of the phandle of the TX and RX shared memory area that
+ the IPC between CPU and BPMP is based on.
+- #clock-cells : Should be 1.
+- #reset-cells : Should be 1.
+
+This node is a mailbox consumer. See the following files for details of
+the mailbox subsystem, and the specifiers implemented by the relevant
+provider(s):
+
+- .../mailbox/mailbox.txt
+- .../mailbox/nvidia,tegra186-hsp.txt
+
+This node is a clock and reset provider. See the following files for
+general documentation of those features, and the specifiers implemented
+by this node:
+
+- .../clock/clock-bindings.txt
+- <dt-bindings/clock/tegra186-clock.h>
+- .../reset/reset.txt
+- <dt-bindings/reset/tegra186-reset.h>
+
+The shared memory bindings for BPMP
+-----------------------------------
+
+The shared memory area for the IPC TX and RX between CPU and BPMP are
+predefined and work on top of sysram, which is an SRAM inside the chip.
+
+See ".../sram/sram.txt" for the bindings.
+
+Example:
+
+hsp_top0: hsp@03c00000 {
+ ...
+ #mbox-cells = <2>;
+};
+
+sysram@30000000 {
+ compatible = "nvidia,tegra186-sysram", "mmio-sram";
+ reg = <0x0 0x30000000 0x0 0x50000>;
+ #address-cells = <2>;
+ #size-cells = <2>;
+ ranges = <0 0x0 0x0 0x30000000 0x0 0x50000>;
+
+ cpu_bpmp_tx: shmem@4e000 {
+ compatible = "nvidia,tegra186-bpmp-shmem";
+ reg = <0x0 0x4e000 0x0 0x1000>;
+ label = "cpu-bpmp-tx";
+ pool;
+ };
+
+ cpu_bpmp_rx: shmem@4f000 {
+ compatible = "nvidia,tegra186-bpmp-shmem";
+ reg = <0x0 0x4f000 0x0 0x1000>;
+ label = "cpu-bpmp-rx";
+ pool;
+ };
+};
+
+bpmp {
+ compatible = "nvidia,tegra186-bpmp";
+ mboxes = <&hsp_top0 TEGRA_HSP_MBOX_TYPE_DB TEGRA_HSP_DB_MASTER_BPMP>;
+ shmem = <&cpu_bpmp_tx &cpu_bpmp_rx>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+};
