+title: Freescale Asynchronous Sample Rate Converter (ASRC) Controller
+
+description:
+  The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of
+  a signal associated with an input clock into a signal associated with a
+  different output clock. The driver currently works as a Front End of DPCM
+  with other Back Ends Audio controller such as ESAI, SSI and SAI. It has
+  three pairs to support three substreams within totally 10 channels.

i'm not sure this is a good idea. In case i.MX6UL(L) is different from i.MX6SX here, then it should have a different compatible.

It already has. The i.MX6UL(L) compatible looks like this:

compatible = "fsl,imx6ul-lcdif", "fsl,imx6sx-lcdif"

So the i.MX6SX one is just a fallback compatible. But the current requirement for power-domains affects i.MX6UL(L), since it says the compatible only needs to contain "fsl,imx6sx-lcdif" somewhere to make power-domains mandatory.

Note, that the kernel driver does not use "fsl,imx6ul-lcdif", so the hardware itself is indeed compatible.

HDMI Audio has been added to the DT binding documentation with an incorrect index. DT and the driver use index 26. This happened, because the binding is missing MULTI_SAI type, which is using index 25.

I just used something slow, which should definitely work. I will try to increase to 1MHz. Note, that the display is not driven via SPI. SPI is just used for the configuration.

Thanks for the review,
