Add gpio cs support. This is dts
&spi1 {
status = "okay";
cs-gpios = <&gpio0 18 GPIO_ACTIVE_LOW>;
non-flash;
spigen@0 {
compatible = "freebsd,spigen";
spi-max-frequency = <10000000>;
};
};
Almost same as OpenWRT. But current code depend on flash access.
I add non-flash property by ignore.
I try RT5350 spi1 registor but not worki fo me. I am abandon.
mode and clock set on transfer.
I use this code on small lcd device.
