Texas Instruments' K3 Remote processor driver
=============================================
In K3 generation Socs, loading an image on any processing entity
cannot be done directly from U-Boot. In order to load an image,
remoteproc driver should communicate to SYSFW with a specific sequence.
Also enable the timer required for this remotecore.
Required properties:
--------------------
- compatible: Shall be: "ti,am654-rproc"
- reg: base address of the remoteproc timer.
- power-domains: Should contain two sets of entries:
First set corresponds to pm domain of the
remotecore timer. Seconf entry corresponds to the
remoteproc to start.
This property is as per the binding,
doc/device-tree-bindings/power/ti,sci-pm-domain.txt
- resets: Should contain a phandle to a reset controller node
and an args specifier containing the remote code
device id and reset mask value. This is as per the
doc/device-tree-bindings/reset/ti,sci-reset.txt
- ti,sci: Phandle to TI-SCI compatible System controller node.
- ti,sci-proc-id: Processor id as identified by TISCI
Optional properties:
--------------------
- assigned-clocks: Should contain a phandle to clock node and an args
specifier containing the remote core device id and
the clock id within the remote core. This is as per
doc/device-tree-bindings/clock/ti,sci-clk.txt
- assigned-clock-rates: One entry for each entry of assigned-clocks. This is
the frequency at which the corresponding clock needs
to be assigned.
- ti,sci-host-id: Host ID to which the processor control is transferred to
Example:
---------
a53_0: a53@0 {
compatible = "ti,am654-rproc";
power-domains = <&k3_pds 61>,
<&k3_pds 202>;
resets = <&k3_reset 202 0>;
assigned-clocks = <&k3_clks 202 0>;
assigned-clock-rates = <800000000>;
ti,sci = <&dmsc>;
ti,sci-proc-id = <32>;
ti,sci-host-id = <10>;
};
