This allows use of some USB peripherals that
utilize the CP210X serial chip.
This includes not only mere UART-to-USB adapters,
but also some devices like GPS, Zigbee dongles,
etc.

This kernel release incorporates the following fix from Megi:
- fixed regression in Pinephone power consumption during sleep (touchscreen
was not disabled properly, consuming a lot of power)
[ci:skip-build]: already built successfully in CI
Add a dummy subpackage that does not install any kernel. This is useful
for testing 'pmbootstrap install' code quickly without actually
downloading and installing a kernel package.
changes:
- don't try to set gnss-share socket in geoclue
- install Alsa UCM configs from purism
Upstream ucm is broken when migrating from the purism ucm, so let's
just use ucm from purism until someone upstreams something that works.
What I upstreamed was based on an older ucm from Purism, what they are
shipping is more correct than upstream ucm...
This reverts commit 70b7813fee.

[ci:skip-build]: already built successfully in CI
Update from librem5-bae 56 to 58, which includes the following changes
from Purism
* default: gadget: Use CDC-NCM instead of CDC-ECM
* defaults: Add an initramfs script to reencrypt LUKS rootfs
* defaults: librem5-pm: Add rules for EM7565 and SIM7912G
* defaults: pulse: Reduce fragment size to 22 ms
* defaults: Switch USB PM timeouts back to 2s for devices and 0 for hub
* defaults: Enable WiFi powersave with brcmfmac driver
* defaults: usb_gadget: Run service as a dependency of UDC device unit
* defaults: usb_gadget: Set Before= relation to network.target
* defaults: librem5-pm: Enable NO_SUSPEND quirk and adjust PM properties
* d/control: Bump Librem 5 kernel dependency to 6.1.19pureos1
Note, that this update doesn't fix the modem disapearing modem during
suspend. So we keep the current workarounds we have.

Enable options required for the Android 11 image inside waydroid:
* CONFIG_BPF_SYSCALL
* CONFIG_CGROUP_BPF
* CONFIG_PSI (already set for this kernel)
* not CONFIG_PSI_DEFAULT_DISABLED (already set for this kernel)
The same will be done for all devices in main and community in the
following patches. Also add V=1 for all kernels I'm modifying that are
below 6.2 (see issue 1990).
Kernel configuration addition:
Just like on the PinePhone Pro I enabled the newly added Lazy RCU scheduler.
RCU_LAZY can help battery-powered systems like the PinePhone Pro in a few ways:
1. Reduced CPU usage: Because RCU_LAZY allows readers to access shared data structures without acquiring locks or other synchronization primitives,
it reduces the amount of CPU time that is required to manage synchronization. This can be particularly beneficial in battery-powered systems,
where reducing CPU usage can extend battery life.
2. Reduced memory usage: RCU_LAZY delays the creation of multiple versions of the shared data structure until they are actually needed.
This reduces the amount of memory that is required to store these versions.
In battery-powered systems, where memory usage can be a critical resource, this can help to conserve power.
3. Reduced synchronization overhead: RCU_LAZY reduces the overhead of synchronization by delaying the creation of multiple versions of the shared data structure.
This can reduce the amount of time that is spent acquiring and releasing locks or other synchronization primitives,
which can help to conserve power in battery-powered systems.

According to Purism, PM on the Sparklan WiFi module works now with
recent kernels, the upstream bug referenced earlier (see diff) was
closed.
Note that this has no effect on the Redpine WiFi module, which is the
default module shipped with the L5.

that is...), and some ucm tweaks.

Installing wys and anything else on all gnome-related UIs is better than
just having a special case for phosh. Phosh should pull in
pmos-base-ui-gnome.
According to
https://source.puri.sm/Librem5/linux/-/issues/303#note_160864 enabling
the modem power management results in a unreliable modem, but more power
savings.
With power management on the modem can disconnect at any time,
including during calls. This makes the Librem 5 a very bad phone.
Instead let's ensure it works as a phone with a semi-reliable modem
(there is still the sleep/resume issue
https://source.puri.sm/Librem5/linux/-/issues/423) at the cost of
battery life.
As the Librem5's battery life is already poor, a little bit worse
isn't much different. Either way you need an external battery pack.

I unset CONFIG_ARM64_PTR_AUTH_KERNEL because the i.MX 8 CPU in the
Librem 5 doesn't support features from ARMv8.1-A and above anyway.
Same rationale applies to CONFIG_ARM64_TLB_RANGE being unset.
