SubjectRE: [PATCH v2 2/3] firmware: imx: scu-pd: Add mu13 b side PD range
Date

> LSIO subsystem contains 14 MU instances.
>
> 5 MUs to communicate between AP <-> SCU
> - side-A PD range managed by AP
> - side-B PD range managed by SCU
>
> 9 MUs to communicate between all cores (AP/M4/DSP).
> - side-A PD range managed by core-A (AP/M4/DSP)
> - side-B PD range managed by core-B (AP/M4/DSP).
>
> Communication between AP <-> DSP is done through the assigned MU number
> 13.
>
> So, we power up side-A by the AP and we decide to power up side-B also from
> AP. This is because powering it up from DSP would be painful.
>
> Powering up side B from DSP would require the DSP to communicate with SCU
> and to keep things simple we don't want that now.
