yes, this is out of sync with the existing format binding. I'll send a patch fixing it.

I meant, you introduce it out-of-order. So this patch should be modified and new compatible added in some better place.

PATCH 2/2 remoteproc: pru: Add support for various PRU cores on K3 AM62x SoCs

In reply to Kishon Vijay Abraham I

The K3 AM62x family of SoC has one PRUSS-M instance and it has two Programmable Real-Time Units (PRU0 and PRU1). This does not support Industrial Communications Subsystem features like Ethernet.

Enhance the existing PRU remoteproc driver to support the PRU cores by using specific compatibles. The initial names for the firmware images for each PRU core are retrieved from DT nodes, and can be adjusted through sysfs if required.
