4f4ed4543e mfd: Replace HTTP links with HTTPS ones
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.

efc9b2048c mfd: tps65218: Reorder tps65218_regulator_id enum
Commit 2dc4940360 ("regulator: tps65218: Remove all the compatibles")
changes the probe function of drivers/regulator/tps65218-regulator.c so
that it iterates through all available regulators and assumes that the
regulator IDs are sequential and match the order present in the enum
tps65218_regulator_id. However, for some reason the much older commit
c0ea88b890 ("regulator: tps65218: add support for LS3 current
regulator") updated all arrays with LS3 at the end but added it second
to last for the enum.

Because of this long standing mismatch in order between the
tps65218_regulator_id enum and the regulator_desc array in the tps65218
regulator driver, the new probe function causes the strobe values to be
associated with the wrong regulator ID. This causes LDO1 to fail to
suspend in tps65218_pmic_set_suspend_disable due to not having anything
probes for its strobe value. Fix the order in the enum so the probe
function works as the update intended.

b9a0d35941 regulator: tps65218: Enable suspend configuration
TPS65218 has a pre-defined power-up / power-down sequence which in
a typical application does not need to be changed. However, it is possible
to define custom sequences under I2C control. The power-up sequence is
defined by strobes and delay times. Each output rail is assigned to a
strobe to determine the order in which the rails are enabled.

Every regulator has sequence registers and every regulator has a default
strobe value and gets disabled when a particular power down sequence
occurs.

To keep a regulator on during suspend we write value 0 to strobe so
that the regulator is out of all sequencers and is not impacted by any
power down sequence. Hence saving the default strobe value during probe
so that when we want to regulator to be enabled during suspend we write 0
to strobe and when we want it to get disabled during suspend we write
the default saved strobe value.
This allows platform data to specify which power rails should be on or off
during RTC only suspend. This is necessary to keep DDR state while in RTC
only suspend.
