Hi Chris,
I'm hijacking this discussion a bit.
I recently tried to boot maline on my Odroid GOA, which I managed to do, except the display wasn't displaying anything :-)
Everything looks good on a quick look, the Inno PHY driver is here, and there's a DRM card registered with the right mode 320x240 and connected status (which I suppose doesn't mean much in this case). Also, the backlight is on.
Looks like this is working for you, so I was wondering if maybe this would ring a bell, or perhaps you're aware of any patches we are missing in v5.11-rc7 (which is what I'm basing on). Or maybe I'm missing some config?...
Any ideas would be welcome!
Ezequiel
