== Charging ==
<code>rt5033-charger</code> driver is not available, so the charging is not controlled and there is no charging status reporting.
There was a forgotten patch<ref>[https://lore.kernel.org/lkml/1425864191-4121-1-git-send-email-beomho.seo@samsung.com/ power: rt5033: Add Richtek RT533 drivers]</ref> from 2015 on the kernel mailing list. Jakko picked up the work on top of that, and the review started in February 2023 <ref>[https://lore.kernel.org/lkml/cover.1677620677.git.jahau@rocketmail.com/ Add RT5033 charger device driver]</ref>.
== USB OTG ==
Another <code>rt5033-charger</code> driver issue. It's currently unable to power up a usb device in mainline. Therefore the otg only work with a usb that has a external power supply (like USB OTG Charging Hub) on some device ( like [[Samsung Galaxy A5 2015 (samsung-a5)]](SM-A5000)).On some another device the otg might not work.
