Hello,
I want to use spi0.1 on rock64 (ver 3.0).
I tried enabling rockchip-spi-spidev in armbian-config, but it didn't work. When I open the dtb, it seems that it is not for rk3328 as there is "compatible = "rockchip,rk3399"".
Where can I find the right dts?
I tired:
add num-cs into the rk3328-rock64.dts
dmesg:
[ 3.239265] rockchip-spi ff190000.spi: Failed to register controller
[ 3.239495] rockchip-spi: probe of ff190000.spi failed with error -22
