Allwinner V3s test VPU Cedrus

Hi there,

 

I'm currently struggling to get the Cedrus VPU up and running. I have downloaded the specific version from bootlin and got the kernel up and running, however the V3s isn't supported by the Sunxi SRAM driver.

This driver is important to get the VPU going. I tried altering the devicetree of the V3s to match a SoC that is somehow similiar, but it clearly failed for obvious reasons.

 

I get this error message:

 

[    1.035259] cedrus 1c0e000.video-codec: Failed to claim SRAM
[    1.040990] cedrus 1c0e000.video-codec: Failed to probe hardware
[    2.478247] cedrus 1c0e000.video-codec: Failed to claim SRAM

[    8.601112] cedrus 1c0e000.video-codec: Failed to probe hardware

 

I tried to understand whats going on in the linux/drivers/soc/sunxi/sunxi_sram.c file to adapt this driver to the V3s, but in the end I don't know how to do that.

I hope somebody can help me with that or can give me a hint.
