A13 OLinuXino MICRO device tree with Mali GPU

[rob2020]

Hi,

I'm trying to get the Mali GPU working with a mainline Linux version. I can't seem to find a device tree containing the Mali 400 GPU for this board (A13 OLinuXino MICRO)? Can anybody help me out? Shouldn't it be in the sun5i.dtsi file soc section?

thank you.

this board has only 256MB of RAM, if I remember correctly Mali alone requires between 128 and 256MB to run, so you will able to use it with board at least with 512MB RAM

I would like to give it a try as a board with more memory would be a cost factor. What would I have to add to the device tree?

thanks.

I think I managed to assemble a working dt with mali GPU enabled. Finally :-)

Code Select Expand

mali: gpu@1c40000 {
                        compatible = "allwinner,sun4i-a10-mali", "arm,mali-400";
                        reg = <0x1c40000 0x10000>;
                        interrupts = <0x45 0x46 0x47 0x48 0x49>;
                        interrupt-names = "gp", "gpmmu", "pp0", "ppmmu0", "pmu";
                        clocks = <0x2 0x31 0x2 0x62>;
                        clock-names = "bus", "core";
                        resets = <0x2 0x9>;
                        assigned-clocks = <0x2 0x62>;
                        assigned-clock-rates = <0x16e36000>;
                        phandle = <0x81>;
                };
This works on A13-WiFi

Can you provide the full dts file ?

or where this extra code is placed ,  thanks
