Subject: [RFC PATCH v2 0/3] regulator: pwm-regulator: Fixes for disabled PWMs at boot
Date: Sat, 13 Jan 2024 23:46:25 +0100 [thread overview]
Message-ID: <20240113224628.377993-1-martin.blumenstingl@googlemail.com> (raw)
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().
