I would like to see tpm_msleep() wrapper to replace current msleep() usage across the subsystem before considering this. I.e. wrapper that internally uses usleep_range(). This way we can mechanically convert everything to a more low latency option.Fine. ?I assume you meant tpm_sleep(), not tpm_msleep().I think it would sense to have a function that takes msecs because msecs are mostly used everywhere in the subsystem. This way we don't have to change any of the existing constants.
For now converting from msleep() to tpm_msleep() will be straight forward. ?Internally we would just use usleep_range(). Going forward, my concern is that even 1 msec might be too long for some of these sleeps.
