Imagination Pistachio SoC
=========================
Required properties:
--------------------
- compatible: Must include "img,pistachio".
CPU nodes:
----------
A "cpus" node is required. Required properties:
- #address-cells: Must be 1.
- #size-cells: Must be 0.
A CPU sub-node is also required for at least CPU 0. Since the topology may
be probed via CPS, it is not necessary to specify secondary CPUs. Required
propertis:
- device_type: Must be "cpu".
- compatible: Must be "mti,interaptiv".
- reg: CPU number.
- clocks: Must include the CPU clock. See ../../clock/clock-bindings.txt for
details on clock bindings.
Example:
cpus {
#address-cells = <1>;
#size-cells = <0>;
cpu0: cpu@0 {
device_type = "cpu";
compatible = "mti,interaptiv";
reg = <0>;
clocks = <&clk_core CLK_MIPS>;
};
};
Boot protocol:
--------------
In accordance with the MIPS UHI specification[1], the bootloader must pass the
following arguments to the kernel:
- $a0: -2.
- $a1: KSEG0 address of the flattened device-tree blob.
