AM62A7-Q1: VPU complaining about missing IRQ and OPP table

Tool/software:

Hi,

I am trying to get my linux to boot without error messages on AM62A, and am seeing the following error messages:

[    0.152707] omap-mailbox 29030000.mailbox: no available mbox devices found
[    3.774684] vdec 30210000.video-codec: error -ENXIO: IRQ index 0 not found
[    3.794242] vdec 30210000.video-codec: failed to get irq resource, falling back to polling
[    3.802955] vdec 30210000.video-codec: OPP table not found in device tree

I'm currently focussing on the video-codec messages, as those look to be easy to solve;

My questions:

  1. What IRQ should I use for the VPU?
  2. What OPP table can I use for the VPU, and how is that used? I need a 500 MHz clock for my application, which I've currently set manually.
    But it wouldn't hurt to have that set dynamically, provided it scales up fast enough.

If you have any ideas about the mbox devices not found error, that would be nice too.

Regards,
