We need the OTP pin is gpio state before resetting the TSADC controller, since the tshut polarity will generate a high signal. "init" pinctrl property is defined by Doug's Patch[0]. Patch[0]: https://patchwork.kernel.org/patch/7454311/ Signed-off-by: Caesar Wang Reviewed-by: Douglas Anderson --- Changes in v3: - Add the "sleep" pinctrl as the gpio state in PATCH[3/3] Changes in v2: - Add some commits for more obvious in PATCH[2/2] Changes in v1: - As the Doug comments, drop the thermal driver patchs since we can with pinctrl changing to work. - As the Doug's patch to add the 'init' property. arch/arm/boot/dts/rk3288.dtsi | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/rk3288.dtsi b/arch/arm/boot/dts/rk3288.dtsi index 906e938..13ff09a 100644 --- a/arch/arm/boot/dts/rk3288.dtsi +++ b/arch/arm/boot/dts/rk3288.dtsi @@ -447,8 +447,10 @@ clock-names = "tsadc", "apb_pclk"; resets = <&cru SRST_TSADC>; reset-names = "tsadc-apb"; - pinctrl-names = "default"; - pinctrl-0 = <&otp_out>; + pinctrl-names = "init", "default", "sleep"; + pinctrl-0 = <&otp_gpio>; + pinctrl-1 = <&otp_out>; + pinctrl-2 = <&otp_gpio>; #thermal-sensor-cells = <1>; rockchip,hw-tshut-temp = <95000>; status = "disabled"; @@ -1273,6 +1275,10 @@ }; tsadc { + otp_gpio: otp-gpio { + rockchip,pins = <0 10 RK_FUNC_GPIO &pcfg_pull_none>; + }; + otp_out: otp-out { rockchip,pins = <0 10 RK_FUNC_1 &pcfg_pull_none>; }; -- 1.9.1
