According to Purism, the imx8mq-librem5.dtb alias is going away soon,
and we should be using the -r2 dtb. The -r2 dtb (which represents
Birch/Chestnut L5 variants) is most compatible, it'll boot on later
variants. dtbs for later L5 devices won't work on older devices.
This is a generic package for devices which use x86_64 CPU and 32-bit
EFI. Most distributions don't provide installation for 32-bit EFI, so
installation is not user-friendly.
Actually, these tablets deserve device-specific packages (I am going to
make ones for ASUS VivoTab Note 8 and ASUS Transformer Book T100TA), but
this one includes basic functions and can be booted on any 32-bit EFI
tablet with disabled secure boot and missing device-specific package.
I guess 32-bit EFI with 64-bit CPU is Intel's "feature" and AMD doesn't
have such stuff, so this package will be installed only on devices with
Intel CPU, unlike device-tablet-x64uefi which can be installed on any
x86_64 PC. So i decided to enable some Intel specific things (userspace
GPU stuff and alsa-ucm-conf).
I used for reference device-tablet-x64uefi and
device-trekstor-surftabduow1 packages. This package also can be used as
a reference for device-specific ones.
Added support for Motorola Moto E 2014 codename: condor
It is booting, has usb, battery, flashing needs special fastboot command for the boot partition
- Upgrade librem5-base to v33
- Include the haptic vibration driver in initfs for supporting osk-sdl's
haptic feedback feature
- remove gps udev rule in pmaports in favor of using rule from
librem5-base
- install modem audio udev rule from librem5-base
- add openrc service for putting device into 'ship mode' on shutdown
(prevents battery from slowly draining)
- include Evergreen/r4 dtb in /boot
- Fix audio with port of ucm config to ucm2 (patch submitted upstream
here: https://source.puri.sm/Librem5/librem5-base/-/merge_requests/214)
Port based on an unofficial LineageOS port
from https://www.los-legacy.de/17.1/zerofltexx, using kernel from https://github.com/Exynos7420/android_kernel_samsung_exynos7420/
What works:
- Kernel boots
- Display and touch input (tested with Weston)
- USB networking
Note: I removed camera support in kernel config for now, as there were related kernel crashes.
Wifi doesn't work either yet because the firmware dependencies/paths need to be fixed first.
The modprobe.conf is not necessary on those devices because they already
load the panel module using deviceinfo_modules_initfs. Let's skip the
modprobe.conf in that case so we don't need to add all panels in two places.
A hack shamelessly stolen from Manjaro. Plasma Mobile runs in the user
session and needs direct access to the sys entries of the flashlight to
be able to toggle it in the GUI
[skip ci] Broken, thinks there is an unreferenced file while there is

Move the shelli-specific alsa config from MR 1741 into a subpackage that
only gets installed together with shelli.
With the config installed, programs using alsa instead of pulseaudio,
can't be controlled through the volume setting in Phosh anymore (and
probably other UIs too). Shelli doesn't use pulseaudio.
Change the path of the config file like in MR 1877, so it's easier to
override it if necessary.
While at it, improve the APKBUILD slightly by fixing the install_if of
the phosh subpkg (should depend on =$pkgver-r$pkgrel, see APKBUILD
reference), and fix long lines.
Simply disabling FIMC IS does not work however due to compilation
errors and a null pointer dereference. 01-fix-FIMC-IS-disabling.patch
takes care of this.
As with other exynos devices some additional things had to be disabled
to make the kernel compile after FIMC IS had been disabled,
specifically:
CONFIG_CAMERA_EEPROM
CONFIG_VIDEO_EXYNOS_MIPI_CSIS
CONFIG_LEDS_MAX77803
Apart from that we also have:
02-netfilter-symbols.patch, which fixes another compilation error.
03-usb_gadget-set-random-rndis-host-MAC-address-to-prev.patch (taken
from another device) which prevents host mac address being set to
00:00:00:00:00.
Kernel sources have been changed to the lineage-16.0 branch in the
exynos5420 repo, as that is where development happens at the moment.
based off from lineage os, manages to boot including ssh over usb.
had to disable:
CONFIG_HTC_RADIO_SMEM
CONFIG_HTC_MODEM_NOTIFIER
CONFIG_MSM_SMP2P
CONFIG_UIO_MSM_SHAREDMEM

This adds eg25-manager for managing modem power in userspace instead of
relying on the modem-power stuff in the kernel. The userspace
eg25-manager has proven to be more reliable than using modem-power.
An older setup-modem script is installed for ofono, since eg25-manager
cannot interface with ofono (yet).
The eg25 init script was removed since it only dealt with configuring
the modem-power driver in the kernel

Instead of running the entire setup_usb_network_configfs function we
run the parts that are actually necessary for
setup_usb_network_android to succeed when it is run afterwards.
USB networking, Touchscreen and display are working.
CONFIG_SND_SOC_QDSP6V2 is omitted from kernel config for now as the resulting driver fails to build.
Upstream changelog:

Suspend is also disabled in the kconfig, since it is not
supported/working on this device
