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]. Changes since v1: - Rebased on top of next and dropped already merged patches. - Dropped LDO4 full range devicetree change for Lime2 (prev patch 9) in favor of general pin-bank regulator dependency [2]. - Fixed paths in devicetree bindings (patch 3) - Added note about software based soft-start for LDO3 (patch 5) [1] https://lists.denx.de/pipermail/u-boot/2018-November/348612.html [2] http://lists.infradead.org/pipermail/linux-arm-kernel/2018-December/618459.html Olliver Schinagl (8): mfd: axp20x: name voltage ramping define properly regulator: axp20x: add support for set_ramp_delay for AXP209 dt-bindings: mfd: axp20x: add support for regulator-ramp-delay for AXP209 regulator: axp20x: add software based soft_start for AXP209 LDO3 dt-bindings: mfd: axp20x: Add software based soft_start for AXP209 LDO3 regulator: dts: enable soft-start and ramp delay for the OLinuXino Lime2 mfd: axp20x: Clean up included headers mfd: axp20x: use explicit bit defines Documentation/devicetree/bindings/mfd/axp20x.txt | 9 +- arch/arm/boot/dts/sun7i-a20-olinuxino-lime2.dts | 2 +- drivers/mfd/axp20x.c | 13 +- drivers/regulator/axp20x-regulator.c | 142 +++++++++++++++- include/linux/mfd/axp20x.h | 4 +- 5 files changed, 161 insertions(+), 9 deletions(-) base-commit: 14cf8c1d5b90a0cf6a8ba51ef59db8da8c7a2622 -- git-series 0.9.1
