Hi Liam, Ranjani,
I am now looking at implementing the PM features
on i.MX platforms and I have some questions.
1) Where can I find some documentation about the SHIM
layer PM related registers.
e.g apollolake/include/platform/lib/shim.h:
#define SHIM_PWRCTL 0
2) I am looking if it makes sense to have some generic Xtensa
code to put the core in reset at PM suspend. I have seen this
registers:
arch/xtensa/include/xtensa/xdm-regs.h:
#define PWRCTL_CORE_RESET
I wonder if this would make sense for Intel side? Is there any documentation
about the PM states of HIfi DSP in Intel integrations?
thanks,
Daniel.
