From: Jagan Teki <jagan@amarulasolutions.com>

max11801 touchscreen on Engicam iCoreM6 Quad module is
connected via i2c1, so add max11801: touchscreen at 48 on i2c1.

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.

Now that I looked at your 2/3 and 3/3 patches you use:

+&i2c1 {
+       max11801: touchscreen at 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.
