Got the focus lens actuator (bu64748) of Poco F1 rear main camera (imx363) working in mainline linux! Yet to be released. Thanks to @NekoCWD's camerctrl (https://gitlab.com/NekoCWD/cameractrl), we got a nice overlay to manually adjust the focus! I m using a custom gnome snapshot build that supports 1440p resolution from here: https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/79523
