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.

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.
This enables the DRAM frequency stats driver that can be useful for debugging
issues with the PinePhone. This came up in a discussion in #pinephone on IRC
where megi was helping a pmos user with idle power draw issues.
This also enables the performance, powersave and userspace devfreq governors.

This gets rid of the Tux army on bootup. While it hurts my soul,
removing Tux from bootup makes it less flickery.

Also added: 0013-media-ov5640-Update-last-busy-timestamp-to-reset-aut.patch
This solves bug of taking greenish pictures with Megapixels, due to
sensor being shutdown to early after taking a picture.

Protect script when ram_freq is not set
Safely load PSCI DTO to enable CPUidle driver: psci_idle
The PSCI DTO shall only be applied if TF-A & Crust
support CPU idle states [0]. Otherwise the CPU usage
will be at 100%. This will not be visible in top,
lead to overheating and battery drain.
Worst case scenario would lead to a fried chip if
the CPU thermal_zone does not work or is not enabled
in DTS.

I have enough other devices to care about, and honestly haven't touched
my PinePhone in a while. Remove myself as Co-Maintainer from all
relevant packages.

This wifi module doesn't ship with the L5, but I have one because it's
generally more stable than the redpine thing that does ship with the
L5... however there's a known problem with having PM enabled on it.
This adds a NM config option, that matches specifically on this
device/driver, to disable wifi. PM for the redpine should not be
affected by this config change.

Backport the Purism patch from https://source.puri.sm/Librem5/linux/-/merge_requests/640
"With this patch, older revisions (2.0) should be able to switch between
166MHz and 800MHz as opposed to being stuck to 800MHz all the time, since
that was the only supported frequency in the OPP table."

Schedutil is a CPU scheduler that is designed to be more efficient than other schedulers, such as the conservative scheduler, in terms of energy consumption.
This is because schedutil uses information about the utilization of individual CPU cores to make more intelligent decisions about when and how to scale the frequency of the CPU.
This can help to reduce the overall power consumption of the device, which can be particularly beneficial for battery-powered devices.
Additionally, schedutil can also help to improve the overall performance of the device by ensuring that the CPU is able to operate at its maximum frequency when needed.
In my personal testing I haven't seen any noticable impact on power consumption, while the performance does certainly noticeably increase
Note: This is only a change in the aarch64 configuration as the armv7 configuration already used the schedutil scheduler as default.

This fixes gnss out of the box on the librem 5, by configuring geoclue
to use gnss-share as a nmea source.
I went this route, of overriding a .service file that invokes geoclue
with a command line option, because forking this .service file is much
nicer than forking geoclue.conf. The conf file will likely change over
time to add new app permissions or whatever, and it's unlikely
(hopefull!) that this .service file will change much upstream...
