Subject: [PATCH v4 0/4] X-Powers Power Supply Improvements
Date: Tue, 14 Jan 2020 21:40:44 -0600 [thread overview]
Message-ID: <20200115034048.24901-1-samuel@sholland.org> (raw)
This series adds some improvements to the axp20x_usb_power power supply
driver to better support suspend/resume and use on mobile devices.
Patch 1 is preparation for changes in following patches.
Patch 2 allows userspace to take the power supply offline.
Patch 3 allows userspace to control the wakeup behavior.
Patch 4 avoids polling USB VBUS presence when possible.
Changes since v3:
- Rebase on power-supply/for-next
- Add Reviewed-by (1-2)
Changes since v2:
- Patch 1 was merged
- Only check ACIN_PATH_SEL when necessary (1)
- Update commit message (5)
- Avoided reordering lines until/unless necessary (5, 7)
- Update comment and add ID check in axp20x_usb_power_set_property
(it seemed more correct than adding another comment) (6)
- Add Reviewed-by where there were no comments (2-4, 7-8)
Changes since v1:
- Add patches 1-2
- Shift value properly in calls to regmap_update_bits (3, 7)
- Use #ifdef instead of #if to avoid -Wundef warnings (4, 8)
- Poll once after an IRQ, instead of setting power->online in the IRQ (9)
- Poll once on resume, in case the state changed during suspend (9)
