SPI SCLK is not generated

In our custom board we are using 3.14.28 kernel.

I am not able to get SPI SCLK.

Please check attached ECSPI register detail.

dts file modification for ecspi3 is as follows.

&ecspi3 {

fsl,spi-num-chipselects = <1>;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_ecspi3>;

status = "okay";

codec_tas: tas@0 {

compatible = "tas";

spi-max-frequency = <20000000>;

reg = <0>;

};

pinctrl_ecspi3: ecspi5grp {

fsl,pins = <

MX6QDL_PAD_DISP0_DAT2__ECSPI3_MISO 0x0b0b1

MX6QDL_PAD_DISP0_DAT1__ECSPI3_MOSI 0x0b0b1

MX6QDL_PAD_DISP0_DAT0__ECSPI3_SCLK 0x0b0b1

MX6QDL_PAD_DISP0_DAT3__ECSPI3_SS0 0x0b0b1

};

What is possible case for SPI SCLK is not generated?

Thanks

Saurabh
