device-samsung-manta: switch to mainline kernel

Bring mainline kernel support to Samsung Manta (Google Nexus 10). System is usable and stable.

Working:

• USB (host/gadget/OTG)
• Touchscreen
• Display
• Battery (could be improved, though)
• Buttons (userspace configuration needed)
• Bluetooth
• HDMI
• WiFi

Not working / not tested:

• Sound
• Sensors
• NFC
• Dock connector
• GPS
• Front camera
• Back camera
• GPU acceleration (Mali)
• GPU acceleration (g2d)

What's the status of these kernel patches? Are they being upstreamed? Also any reason to base on v6.1 instead of a newer release e.g. v6.5.

They are not being upstreamed at the moment (not sure how patches for only partial support of a new board would be welcomed there, any view on that?). No particular reason for going with 6.1.

Please submit your patches at https://gitlab.com/exynos5-mainline/linux to master branch, we will then backport it to our lts branch, and it will land pmaports with the next linux-postmarketos-exynos5 upgrade. Then you can switch this package to using linux-postmarketos-exynos5 instead

Your manta-usb.patch should be adjusted to not affect other devices. Other patches should be almost fine. We can discuss it at exynos5-mainline/linux MR if you open one

I don't like having it separately, so I'm not reviewing it further for now

It looks like a great way forward, thanks.

I think the process then will be: (1) to close this MR, then (2) make an MR and figure kernel things out in https://gitlab.com/exynos5-mainline/linux, and finally (3) re-open a new MR here regarding changes to device-samsung-manta and firmware-samsung-manta. Is this understanding correct?

By Alexandre Marquet on 2023-09-18T20:17:50

It doesn't matter much. We can take care of it in exynos5-mainline/linux, then you can update this MR (force-push your branch)

Following initial support of Manta in !4483 (merged):

• new configuration for linux-postmarketos-exynos5 to enable drivers needed by this device
• update firmware-samsung-manta so that firmware names match what mainline drivers look for
• remove entries from firmware-samsung-manta that are already in Alpine linux-firmware-*
• switch device-samsung-manta to linux-postmarketos-exynos5 and move downstream device and kernel to unmaintained
