List of phandle and PM domain specifier as documented inDocumentation/devicetree/bindings/power/power_domain.txtHow many? 4?
Yes, 4 for i.MX8QXP. Also, the same number is for i.MX8QM. Anyhow, I didn't added added a limit here because I really don't know how many will be in upcoming i.MX platforms.
Which 4? It might help to use power-domain-names explicitly just like it's done for clocks and mboxes.
This is very common for phandle lists.
4 like in the example at the bottom of the patch:
+ power-domains = <&pd IMX_SC_R_MU_13A>, + <&pd IMX_SC_R_MU_13B>, + <&pd IMX_SC_R_DSP>, + <&pd IMX_SC_R_DSP_RAM>;
Not sure if it makes sense to use power-domain-names as the driver parses directly the "power-domains" property.
