This raises CONFIG_RCU_CPU_STALL_TIMEOUT from 21s to 60s and
CONFIG_RCU_EXP_CPU_STALL_TIMEOUT from 20ms to 60ms (the value `0` means
that it is set to the regular stall timeout divided by 1000).
The original values caused frequent kernel logs of
"rcu_preempt detected expedited stalls" while running CPU-intensive stuff
like waydroid and caused such processes or others like Phosh to crash.
The kernel defaults are 21 / 0 (21s / 21ms), though the config docs note that
the latter is "normally 20ms on Android devices". For what it's worth,
Debian 12's amd64 kernel uses the kernel defaults of 21 / 0 (21s / 21ms),
while OpenSUSE TW's amd64 kernel uses 60 / 0 (60s / 60ms) just like
this commit.
Ref: #2980
- 0003-dts-pinetab-add-missing-bma223-ohci1.patch
The original patch added a node for BMA223 and a node for ohci1.
The former is already present in upstream, so the new patch
0003-dts-pinetab-add-missing-ohci1.patch only adds the latter.
- 0004-arm64-dts-allwinner-Add-bluetooth-node-to-the-PineTa.patch
The patch is now present in upstream so it has been removed.
However it's worth noting that upstream's node has the wake GPIOs
reversed from the original patch. The original patch added:
device-wake-gpios = <&r_pio 0 6 GPIO_ACTIVE_LOW>; /* PL6 */
host-wake-gpios = <&r_pio 0 5 GPIO_ACTIVE_HIGH>; /* PL5 */
... while upstream has:
device-wake-gpios = <&r_pio 0 5 GPIO_ACTIVE_LOW>; /* PL5 */
host-wake-gpios = <&r_pio 0 6 GPIO_ACTIVE_HIGH>; /* PL6 */
This has not been tested on a PineTab.

The issues found with the previous upgrade to 6.8.4
( 646e0b50df ), ie reliably receiving calls
in suspend ( #2734 ) and the headset / headphones detection being broken
because of the jack detection changes ( #2738 ) have been fixed.
[ci:skip-build]: already built successfully in CI
Kernel 6.8.4 has multiple issues on the pine64-pinephone:
- Incoming calls don't work reliably when the phone is suspended. ( #2734 )
- Audio routing has changed such that it's seemingly not possible to use
headphones with the builtin mic. ( #2738 )
Kernel 6.7.9 does not have these problems. This commit reverts to that for now
until they're figured out on the new kernel.

Fixes#2349. Patches refreshed because some didn't apply when I built
directly from local repo and tried to import them with "git am".
Known issue: NetworkManager fails to assign IP to usb0, I had to
assign it manually to use USB networking.
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.

was not disabled properly, consuming a lot of power)

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.

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.

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.

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.

Kernel source updated to 6.1-rc7
Ext2 and Ext3 modules in aarch64 config disabled because Ext4 is backwards compatible.
2 fixes for PinePhone included in this source:
pinephone: fix power key behavior during suspend (avoid stuck key during resume)
pinephone keyboard: wait for 100ms after enabling power supply and before probing.

Remove the -dev subpackages of kernels that replace the linux-headers
package. As I understand, the only case where this would make sense is
if you wanted to build a kernel module against headers that need to be
newer than the headers in Alpine's linux-headers package (currently
5.19.5).
While this might have been historically relevant when wireguard wasn't
in the kernel and you might have needed newer linux-headers to build
the module, it seems irrelevant today. If somebody should need this in
the future, then bring it back properly / consider getting the
linux-headers package in Alpine upgraded. Right now the -dev packages
are broken in several ways:
* Use of unversioned provides= (pma#1766)
* Don't contain binaries needed to build binary packages (pma#462).
This was worked around in 6aba5f ("Package kernel-scripts
separately"), but later this didn't build anymore and we removed it.
So in short: broken and unused, drop them.
