Commit 2dc49403 ("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
c0ea88b8 ("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.

Currently, capture is based on timeout window to configure prescaler.
PWM capture framework provides 1s window at the time of writing.

There's place for improvement, after input signal has been captured once:
- Finer tune counter clock prescaler, by using 1st capture result (with
arbitrary margin).
- Do a 2nd capture, with scaled capture window.
This increases accuracy, especially at high rates.

Add support for PMW input mode on pwm-stm32. STM32 timers support
period and duty cycle capture as long as they have at least two PWM
channels. One capture channel is used for period (rising-edge), one
for duty-cycle (falling-edge).
When there's only one channel available, only period can be captured.
Duty-cycle is simply zero'ed in such a case.

Capture requires exclusive access (e.g. no pwm output running at the
same time, to protect common prescaler).
Timer DMA burst mode (from MFD core) is being used, to take two
snapshots of capture registers (upon each period rising edge).
