This workaround is basically identical to the one recently
applied to soc-qcom-msm8916 (MR 4958).
Tested on xiaomi-tissot and xiaomi-daisy, where performance for
GTK4 applications goes from barely usable to fairly decent.

The modem requires firmware to be loaded from an on-device RADIO partition, samsungipcd does that. Not installing it prevents that firmware from being used.

With the new changes in lk2nd that allow us to support extlinux.conf and
with the U-Boot support with EFI, we can now generate image that would
be generic to these devices.

This one has stalled a bit due to some upstream shenanigans,
but is now confirmed to be fine; since it hasn't been merged
yet, add it here manually.

This new package covers all three variants of the tablet: the WiFi
version (SM-T310), the 3G version (SM-T311) and the LTE version
(SM-T315). It uses the linux-postmarketos-exynos4 kernel, like other
mainlined Exynos 4 devices.
- The 3 different variants of the lt01 will be merged into a single
main device package, so the old package is deprecated.
- We will now be using the mainline kernel, so the downstream kernel is
no longer necessary.
- Add a patch to fix a new build error.
The binaries are the same as for the other devices, we just need to add three
new NVRAM TXTs, so add them here since they don't make the package that much
larger.
eg25-manager is supposed to watch for the modem going away and recover it
automatically, but it doesn't seem to actually do anything.
Manually restarting eg25-manager in this situation does recover the modem.
This upstream issue https://gitlab.com/mobian1/eg25-manager/-/issues/47
is probably the same, and as that issue says, manually restarting eg25-manager
in this situation does recover the modem.
So this change adds a udev rule to automatically restart eg25-manager when
the modem dies. Common triggers for the modem dying are:
1. When the phone wakes up from suspend.
2. When an incoming call is disconnected, especially if the disconnect happens
very quickly after the call started, such as what happens when
phosh-antispam identified the call as spam.
3. When plugging or unplugging the phone from USB power, and when plugging
or unplugging other USB devices like keyboard from a connected dock.
udev shouldn't be used for spawning long-lasting processes,
but `rc-service start` will parent the process to the service manager and exit,
so that's fine. It does take a few seconds during which udev is blocked and
can't process other events, which udev also recommends against,
but in this case it's not a big deal IMO.

The data is not 100% accurate, but it's the best I've got
and it makes the device usable, which it currently isn't.

GTK4 has switched to a new renderer. Unfortunately adreno a306 is
effectively abandoned in mesa and has many bugs which the new GTK
renderer now hits.
To allow us to still use GTK4 apps on the msm8916 based devices, force
the old renderer on them for now.
Fixes: #2681

I contribute to this package from time to time, so let's add myself to
maintainers to represent it here.

This upgrades kernel to 6.6.22 backporting fixes for major performance
issues of Microsoft Surface RT.
This also re-generates config with "make grate_defconfig pmos.config"
and adds pmb:kconfigcheck-uefi for surface rt.
Now as boot-deploy allows us to generate both boot.img and extlinux.conf
at the same time, enable generating the config for all msm8226 since it
will be used in the future lk2nd release. boot.img is still kept to keep
compatibility with current lk2nd releases and to allow system recovery
with fastboot when required.

pmOS does not support charge mode anyway, and boots to a full UI, but this vendor kernel disables touchscreen when booting in charge mode. Remove that check, so that the phone can be used as usual.

Current 6.6 kernel has some features broken for xiaomi-polaris including
LCD and Wi-Fi.
Add two patches that fix these problems.
