What about other non-CPU devices? Are there no sensors or implementation currently doesn't support them? Is this implementation and ACPM TMU support exclusive only to GS101 SoC? IIRC, mapping could be different for other SoCs and, for instance, last sensors could be non-CPU devices. Best regards, Alexey [..]
