Pull operating performance points (OPP) framework fixes for 5.9-rc4 from
Viresh Kumar:

"This fixes reference counting for OPP tables. Few patches are getting
 queued (for various subsystems) for 5.10 which depend on this to be
 fixed first."

  opp: Don't drop reference for an OPP table that was never parsed

opp: Don't drop reference for an OPP table that was never parsed

2020-08-31T09:19:47+00:00

dev_pm_opp_remove_table() should drop a reference to the OPP table only
if the DT OPP table was parsed earlier with a call to
dev_pm_opp_of_add_table() earlier. Else it may end up dropping the
reference to the OPP table, which was added as a result of other calls
like dev_pm_opp_set_clkname(). And would hence result in undesirable
behavior later on when caller would try to free the resource again.

opp: Enable resources again if they were disabled earlier

2020-08-20T06:00:22+00:00

dev_pm_opp_set_rate() can now be called with freq = 0 in order
to either drop performance or bandwidth votes or to disable
regulators on platforms which support them.

In such cases, a subsequent call to dev_pm_opp_set_rate() with
the same frequency ends up returning early because 'old_freq == freq'

Instead make it fall through and put back the dropped performance
and bandwidth votes and/or enable back the regulators.

opp: Put opp table in dev_pm_opp_set_rate() if _set_opp_bw() fails

2020-08-17T05:07:10+00:00

We get the opp_table pointer at the top of the function and so we should
put the pointer at the end of the function like all other exit paths
from this function do.

opp: ti-opp-supply: Replace HTTP links with HTTPS ones

2020-07-24T02:35:54+00:00

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.
