johnty got a reaction from gounthar in 4kp30 video on Orange Pi Lite and mainline hardware acceleration
response my post , also to @ubobrov,
I found that node reserved-memory should be outside of SOC,
after fixing it , the CMA creating works now.
But when installing the sunxi_cedar.ko, it reports
"sunxi-cedar 1c0e000.video-engine: syscon failed..."
I found the syscon entry is different inside sun8i-h3.dtsi at kernel 5.4.16.
