> Please use latest macros (e.g. DEFINE_SIMPLE_DEV_PM_OPS).
When looking at these *_PM_OPS* macros that replace the deprecated versions, it is unclear to me how to maintain support for *_sys_* and
*_sys_*_noirq* functions. Would these all need to be separately defined via DEFINE_SIMPLE_DEV_PM_OPS?
Would the *_sys_* definitions still be defined through a struct i.e.
const struct dev_pm_ops cs40l26_sys_pm_ops which is then exported as it is in my initial submission?
I’m unsure how to handle these cases with the latest macros.
Appreciate any guidance you can provide.
Best regards,
Fred
