[yocto] iMX6UL dtsi SAI1

[Stefano Zuín]

Hi there,

I'm developing a device based on iMX6UL and I need to enabled SAI1 with 
MCLK as output (generated internally). I define SAI1 and iomuxc as 
follows above and I can see in .../pinctrl-maps file that those pins 
have been asigned to SAI1. But I can't get this signals in the 
oscilloscope (neither MCLK). Have any of you experience with this?

Regards!
