+title: NXP i.MX Cortex-A Core Remote Processor via PSCI

+
+description:
+ This binding provides support for managing Cortex-A cores as remote
+ processors on i.MX platforms using the PSCI (Power State Coordination
+ Interface) for CPU power management operations. This allows single
+ Cortex-A core or multiple Cortex-A cores to be controlled by Linux as
+ a remote processor, enabling them to run RTOS or bare-metal applications.
+
+properties:
+ compatible:
+ const: fsl,imx-rproc-psci
+
+ fsl,cpus-mask:
+ $ref: /schemas/types.yaml#/definitions/uint32
+ description:
+ Bitmask indicating which CPU cores are assigned to this remote
+ processor instance. Each bit represents a CPU core, where bit N
+ corresponds to CPU N. For example, 0x2 (0b10) assigns CPU core 1,
+ while 0x6 (0b110) assigns CPU cores 1 and 2.
+
+ memory-region:
+ maxItems: 1
+ description:
+ Phandle to a reserved memory region to be used for the remote
+ processor's code and data.
+
+required:
+ - compatible
+ - fsl,cpus-mask
+ - memory-region
+
+additionalProperties: false
+
+examples:
+ - |
+ remoteproc-ca55-1 {
+ compatible = "fsl,imx-rproc-psci";
+ /* bitmask: 0b10, assign A55 Core 1 */

Normally, we only keep one patch or patch series from the same author that
modifies the same file in the review queue at a time.
You already have a patch for imx_rproc.c currently under review(got R-b, but
need Mathieu to handle), so this patch series might be delayed to be reviewed.
As I have replied in internal, to make multiple OS run on Cortex-A SMP without
hypervsior, some GIC changes are required, without those GIC changes,
this patchset is not testable using upstream tree.
Thanks,
Peng
