The new sound card DT binding is used for Odroid XU3 in order
to properly support the HDMI audio path.
Clocks configuration is changed so the I2S controller is now the bit
and the frame clock master with EPLL as the root clock source.
Patch looks good but I do not understand this last sentence. What did
you want to say?
Which part is hard to understand exactly? Perhaps this is clearer?

"Clocks configuration is changed so the I2S controller is now the bit
clock and the frame clock master.  The EPLL output clock is now the
audio root clock adjusted to each audio sample rate."

Previously the CODEC's internal PLL was used for generating the I2S
bit and frame clocks accorrding to each audio sample rate.
Ahhh, makes sense, the previous "is not the bit and..." mislead me. I
thought it's a typo, you wanted to use "but" and something is missing.
The extended description is I think better, so I'll use it in commit
msg when applying.

Best regards,
Krzysztof
