No spaces before or after '='.

This line is still too long. Please wrap it at 80. Checkpatch should
complain about it... so it seems you did not run it. Please fix all
checkpatch issues.

Put reg after compatible.

You mean " = ", don't you?

My idea was too keep assigned-clocks and assigned-clock-parrent lines
aligned, so it is clearly visible which parrent applies to which
clock. Is it inappropriate?

Ah, of course.

The line gets too long and in the existing DTSes we wrapped item by
item. Solution could be to add comments, e.g.:
assigned-clock-parents = <&cmu CLK_FOUT_MPLL>,
           <&cmu CLK_DIV_MPLL_PRE>, /* for: CLK_DIV_MPLL_PRE */
           <&cmu CLK_MOUT_SPI0>, /* for: CLK_MOUT_SPI0 */

but I am not sure if dtc allows such comments.

Best regards,
Krzysztof
