Notes

Display

There isn't any support for DECON and DSI yet, so panel drivers aren't a thing. However, display is known work with simple-framebuffer with most devices.

Wi-Fi

Wi-Fi behaves very erratically (practically unusable) when the SDIO is probed in DMA mode. The driver fails to communicate with the SDIO, reporting timeout errors. As a workaround, the SDIO is forced to be probed in PIO mode.

Modem

Modem is known to work with an experimental out-of-tree driver developed by sleirsgoevy.
