The `msm-fb-refresher` updates the screen for msm based devices. It is
not needed for all devices, so we had some extra code in the initramfs,
that would only add it when the `deviceinfo_msm_refresher` variable was
set. However, we are able now to add files to initramfs hooks, so this
hack can be removed and simplify everything.
Changes:
* Remove `deviceinfo_msm_refresher` from all deviceinfos
* Add sanity check for it
* Move all `deviceinfo` sanity checks to an extra function
* `postmarketos-mkinitfs`: remove code for msm refresher
* `msm-fb-refresher`: add initramfs hook
The device is Xiaomi Redmi 1S, based on MSM8296 platform, with Qualcomm
Snapdragon 400. The kernel is from lineageOS (3.4.0). Some additional patches
are needed for successful compilation. The screen dimension is 720x1280.
The touchscreen device name is ft5x06_i2c. Use this name for udev
instead of hardcoded device path. Also add a workaround for red
screen weston by setting weston_pixman to 2
The screen doesn't refresh. Enabling msm-fb-refresher as suggested.
Add udev rule to indicate whether the device is in charging state.
Green led indicates that the device is charging, whereas red light
indicates that the device is discharging.
For prima wlan module to work, an initialization procedure is needed (
echo 1 > /dev/wcnss_wlan ), before loading the prima wlan module
(wlan.ko). Also build the prima wlan as module.
Xiaomi Redmi 1S is using pronto wlan module, which needs some firmware
to run. Add the required wifi firmware to enable the wifi interface.
Add an openrc service to load wlan module after wcnss_service is
initialized.
