Subject: [PATCH 00/14] regulator: axp20x: Stop AXP209 from crashing when enabling LDO3
Date: Mon, 26 Nov 2018 17:27:41 +0200 [thread overview]
Message-ID: <cover.156212c9c5df493e098556cad9793a07dcab5e32.1543245984.git-series.plaes@plaes.org> (raw)
This series implements voltage ramping for AXP209 DCDC2 and LDO3
regulators and software based soft-start for AXP209 LDO3 regulator.
Both features are needed to work around a PMIC shutdown when
toggling LDO3 on certain boards with high capacitance on the
LDO3 output.
Similar features (or workarounds) have been also implemented
on u-boot side [1].
Also included in this series are various magic constant cleanups
and also fix for core regulator framework, where 'always-enabled'
constraint overrides the 'soft-start' and 'ramp-delay' features.
