You can use clock delay between packets dt property to set up the delay between the clock cycles.
could you give me complete configure , thank you.
This is the original configuration of the device tree:
spi@3210000 {
status = “okay”;
spi@0 {
compatible = “spidev”;
reg = <0x0>;
spi-max-frequency = <33000000>;
nvidia,rx-clk-tap-delay = <0x11>;
};
};
Add nvidia,clk-delay-between-packets like below.
..
..
spi@0 {
compatible = “spidev”;
reg = <0x0>;
spi-max-frequency = <33000000>;
nvidia,rx-clk-tap-delay = <0x11>;
controller-data {
nvidia,clk-delay-between-packets = <10>;
};
};
..
