Alex, Ezequiel

I'm playing with 5.16 mainline on rk3566 based tvbox (x96-x6)

Box boots and I have working SD card, Eth, HDMI.

I applied this series as I want to get GPU working but I'm getting:

[ 3.169144] panfrost fde60000.gpu: get clock failed -517
[ 3.169646] panfrost fde60000.gpu: clk init failed -517
[ 3.213653] panfrost fde60000.gpu: get clock failed -517
[ 3.214156] panfrost fde60000.gpu: clk init failed -517

[ 3.231006] panfrost fde60000.gpu: clk init failed -517
[ 3.258072] panfrost fde60000.gpu: get clock failed -517
[ 3.258575] panfrost fde60000.gpu: clk init failed -517

Maybe you have some hints here?

517 is EPROBE_DEFER, which implies it's waiting for the relevant clock provider to show up. I see from patch #2 that SCMI is involved, so I'd check that that's working and you have CONFIG_COMMON_CLOCK_SCMI enabled.
