@The Coolest My device is Zoomtak Upro based on S912.
Controller chip if FD628. Extracted from stock android image dts is attached.I suppose the node for FD628 driver is:
m1-vfd {
compatible = "amlogic,m1-vfd";
dev_name = "m1-vfd.0";
status = "okay";
vfd_stb_pin = <0x35 0x49 0x0>;
vfd_clk_pin = <0x35 0x47 0x0>;
vfd_data_pin = <0x35 0x48 0x0>;
};
Is it correct that the configuration file should contain
vfd_gpio_clk='1,73,0'
vfd_gpio_dat='1,71,0'
vfd_gpio_stb='1,72,0'
The rest in config file I hope to find experimenting. Do you have better proposal?
