-NVIDIA Tegra186 BPMP I2C controller
-
-In Tegra186, the BPMP (Boot and Power Management Processor) owns certain HW
-devices, such as the I2C controller for the power management I2C bus. Software
-running on other CPUs must perform IPC to the BPMP in order to execute
-transactions on that I2C bus. This binding describes an I2C bus that is
-accessed in such a fashion.
-
-The BPMP I2C 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 an I2C controller. See ../i2c/i2c.txt for details of the
-core I2C binding.
-
-Required properties:
-- compatible:
- Array of strings.
- One of:
- - "nvidia,tegra186-bpmp-i2c".
-- #address-cells: Address cells for I2C device address.
- Single-cell integer.
- Must be <1>.
-- #size-cells:
- Single-cell integer.
- Must be <0>.
-- nvidia,bpmp-bus-id:
- Single-cell integer.
- Indicates the I2C bus number this DT node represent, as defined by the
- BPMP firmware.
-
-Example:
-
-bpmp {
- ...
-
- i2c {
- compatible = "nvidia,tegra186-bpmp-i2c";
- #address-cells = <1>;
- #size-cells = <0>;
- nvidia,bpmp-bus-id = <5>;
- };
-};
