- 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>;
- };
