How to enable spi of VIM3l(S905D3)

Hello dear @numbqq @Frank:
I want to make SPI(or SPICC) to be enabled on S905D3, but it doesn’t work. Would you tell me how to do it?
I have tried.

  1. Set “spicc0” and “spicc1” in file “kvim3l.dts”, like below:
	status = "okay";
	status = "okay";

2.Set the environment variable “spi_state” to “1”, in bootloader
Even so the function “meson_spicc_probe” of “spi_meson-spicc.c” doesn’t be called.

@minglong.cheng Please follow this docs. You need to enable it with overlays
