From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>
Per the current binding, QM/QXP DSPs are supposed to have 4
power domains, while the rest just 1. For QM/QXP, the 4 power
domains are: DSP, DSP_RAM, MU13A, MU13B.
First off, drop MU13A from the count. This is attached to the
platform device of lsio_mu13. This decreases the count to 3.
Secondly, drop DSP and DSP_RAM from the count for QXP. These
are attached to the platform devices of the lpcgs (used as clock
providers for the DSP).
With this in mind, the number of required power domains for QXP
is 1 (MU13B), while for QM it's 3 (MU13B, DSP, DSP_RAM).
Additionally, two extra power domains may be required in the case
of QM/QXP DSPs. These are IRQSTR_DSP and MU2A. For the nodes using
the "-hifi4" compatibles these PDs are optional, while for nodes using
the "-dsp" compatibles these are mandatory.
These changes reflect all of this information.

What's a platform device? Sounds like some Linux implementation detail.
