oh...,I will fix it.

Maybe,I guess  your mean as the follows .
Please correct it and  Laugh out if I got it wrong.

tsadc {
             otp_out: otp-out {
                 rockchip,pins = <0 10 RK_FUNC_GPIO &pcfg_pull_none>;
             };

             tsadc_int: tsadc-int {
                 rockchip,pins = <0 10 RK_FUNC_1 &pcfg_pull_none>;
             };
         };
Then,I deal with the otp_out in thermal driver.
I believe The "otp_out" will restart board if it's a high active.

tsadc_int: tsadc-int {
+				rockchip,pins = <0 10 RK_FUNC_1 &pcfg_pull_up>;
+			};

But,I think the about will be implemented in thermal driver.
