Why not "maxim,max11801"? Also, I think we'd need a binding document.

Compatibility purpose to make this is for touchscreen and few of other
*_ts.c files follow the same, and added binding documentation in 2/3
patch.
thanks!

Compatibility with what? The i2c id is "max11801" (without the "-ts").

Sorry, it seems I am only copied on 1/3 patch.
Thanks.

Now that I looked at your 2/3 and 3/3 patches you use:
+&i2c1 {
+ max11801: touchscreen@48 {
+ compatible = "maxim,max11801";
+ reg = <0x48>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <31 2>;
+ };
+};
so the compatible you are adding to the driver is definitely wrong.
By the way, it would be nice if you used symbolic constants to express
interrupt trigger type.
Thanks.

Do we need to sync with i2c id as well? egalax_ts.c follow "_ts"
of-course the i2c there as follow the same.
