Panel Partial Only supported hx8933, ili8707 and otm1911 models (not sure if there are any other panels)

Modem

Firmware loads and modem boots. It detects SIM card and can be unlocked and configured with qmicli.

Because audio needs more work i couldn't test audio quality on calls but with q6voiced it should work.

Mobile data

Mobile data works with ipa-lite on 6.7.0/main branch.

To configure the mobile network settings, use NetworkManger (mobile network menu on phosh settings) so it sets up the network interface and IP routing.

After that, two new network interfaces should appear. The rmnet one is the connection to the modem, and the other one is virtual and the one that is used to transmit mobile data.
