[RFC PATCH v2 0/3] regulator: pwm-regulator: Fixes for disabled PWMs at boot

From: Martin Blumenstingl

This is the second version of an attempt to fix booting mainline Linux
on Meson8b Odroid-C1.
This series is an update to an RFC patch that I sent some time ago [0]
and incorporates a lot of the feedback from that v1.

The main changes since v1 [0] are:
- new patch checking the voltage limits in pwm_regulator_get_voltage()
- updated calculation for disabled regulators in+
pwm_regulator_get_voltage() utilizing above limit checking
- new pwm_regulator_init_boot_on() to preserve the output voltage when
pwm_regulator_enable() later enables the PWM output without and
preceding pwm_regulator_set_voltage().

regulator: pwm-regulator: Add validity checks in continuous
.get_voltage
regulator: pwm-regulator: Calculate the output voltage for disabled
PWMs
regulator: pwm-regulator: Manage boot-on with disabled PWM channels
