Hi Paul,

Two things:

I have tested the whole series on my Creator CI20 with success, using:

+ tcu@...02000 {
+ compatible = "ingenic,jz4780-tcu";
+ reg = <0x10002000 0x140>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <27 26 25>;
+ };


So:

When working on JZ4780 support, I always struggle to read those kind
of #define. Since this is a new patch would you mind changing
s/JZ4740/JZ47XX/ in your header ?

Thanks for your work on JZ !
