regulator: rc5t583: Get rid of struct rc5t583_regulator
The struct rc5t583_regulator only has 2 members, the *rdev is no longer
used because this driver is using devm_regulator_register now. After remove
*rdev, only *reg_info left. We can use struct rc5t583_regulator_info
directly, so remove struct rc5t583_regulator.

regulator: act8865: Convert to regulator core's simplified DT parsing code
Use regulator core's simplified DT parsing code to simply the driver
implementation. With this conversion, also move the NULL test against pdata
in act8865_get_regulator_data() to the caller. This makes it clear the
code path to explicitly set init_data is for non-DT case only.

regulator: tps65217: Simplify linear range for selector 25-52
The original code separates the selector 25-52 into 2 ranges on purpose
because DCDC1/DCDC3 only support up to 1.8V/1.5V in the old code.
Both DCDC1 and DCDC3 support up to 3.3V since commit b4c2e158a1
("regulator: tps65217: Allow DCDC1 and DCDC3 up to 3.3V"), so merge
25-30 and 31-52 ranges to one range.

regulator: axp20x: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warnings:

drivers/regulator/axp20x-regulator.c: In function ‘axp20x_set_dcdc_freq’:
drivers/regulator/axp20x-regulator.c:1023:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
   reg = AXP803_DCDC_FREQ_CTRL;
drivers/regulator/axp20x-regulator.c:1025:2: note: here
  case AXP806_ID:
  ^~~~
drivers/regulator/axp20x-regulator.c: In function ‘axp20x_set_dcdc_workmode’:

   reg = AXP806_DCDC_MODE_CTRL2;
drivers/regulator/axp20x-regulator.c:1121:2: note: here
  case AXP221_ID:
  ^~~~

Notice that in this particular case, I moved the whole comment
"Fall through to the check below.", which contains the "Fall through"
comment, at the bottom of the case, which is what GCC is expecting
to find.

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

regulator: core: Fix application of "drop lockdep annotation in drms_uA_update()"
[The original commit was sent against -next but needed to be sent as a
bugfix, however -next had some additional changes which needed to be
reverted.  Now everything is all in one branch applying the rest of the
changes to fix up the merge issue -- broonie]

commit e5e21f70bf ("regulator: core: Take lock before applying system
load") took the regulator lock before calling drms_uA_update() in order
to silence a lockdep warning during regulator_register().

However, we are not supposed to need locks at this point as the regulator
is in the process of being registered, so there should be no possibility
of concurrent access.

Instead, remove the unnecessary locking and simply drop the lockdep
annotation, since it is no longer valid.

I already reported this as a bug in clang, but it may take a
while to fix it. As I have not been able to come up with any
reasonable workaround, I would just disable compilation here.

regulator: pv88060: Fix notifier mutex lock warning
The mutex for the regulator_dev must be controlled by the caller of
the regulator_notifier_call_chain(), as described in the comment
for that function.

Failure to mutex lock and unlock surrounding the notifier call results
in a kernel WARN_ON_ONCE() which will dump a backtrace for the
regulator_notifier_call_chain() when that function call is first made.
The mutex can be controlled using the regulator_lock/unlock() API.
