Clock is not coming
My Pin mux settings are as follows
&ecspi2 {
fsl,spi-num-chipselects = <1>;
cs-gpios = <&gpio4 22 0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_spi>;
status = "okay";
spidev@0x00 {
compatible = "spidev";
spi-max-frequency = <20000000>;
reg = <0>;
};
};
&iomuxc {
.....
pinctrl_spi: spigrp{
fsl,pins = <
MX6UL_PAD_CSI_DATA00__ECSPI2_SCLK 0x100b1
MX6UL_PAD_CSI_DATA02__ECSPI2_MOSI 0x100b1
MX6UL_PAD_CSI_DATA03__ECSPI2_MISO 0x100b1
MX6UL_PAD_CSI_DATA01__GPIO4_IO22 0x80000000
>;
};
...
No clock signal. SS0 is always high
/dev/spidev1.0 is getting enumerated
cs-gpio is coming as spi_imx

Let me know what am missing
