error: pasting "_XXXX" and "(" does not give a valid preprocessing token

Question

Im trying to enable rtc rv8263 support by copying changes made to support it from

https://github.com/zephyrproject-rtos/zephyr/commit/37d6bc082782f0b66420c68f4ff57db5eb283d90

https://github.com/zephyrproject-rtos/zephyr/commit/db9b45a7b3f0d2a2b63a840d8d7d3abfcdb7709b

github.com/.../4c880f4b0a5fa6d55d731ddfec8b040361998427

to my nordic zephyr at /opt/nordic/ncs/v2.6.1/zephyr

I use the nrf52840dk board

Added this to prj.conf:

CONFIG_I2C=y

CONFIG_RTC=y

CONFIG_RTC_RV8263=y

This is what i added to app.overlay:

&i2c0 { /* SDA P0.26, SCL P0.27 */
	status = "okay";
	rv8263: rv8263@68 {
		compatible = "microcrystal,rv-8263-c8";
		reg = <0x68>;
		status = "okay";
        int-gpios = <&gpio0 0 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;
		clkout = <32768>;
	};
};

Currently i get the following compile error:

rv8263_support.patch

I have attached git patch that contains all the changes i have made to nrf sdk zephyr installation. This can be applied by:

cd /opt/nordic/ncs/v2.6.1/zephyr

git apply /path/to/rv8263_support.patch

to easily make the same changes i have made to reproduce the issue.

How to resolve this compile issue?

Using nRFConnect SDKv2.7.0 fixed the issue. After switching sdk, copied the rv8263 support changes from https://github.com/zephyrproject-rtos/zephyr/commit/37d6bc082782f0b66420c68f4ff57db5eb283d90 into the v2.7.0/zephyr. Also added some things to devicetree:

	i2c0_default: i2c0_default {
		group1 {
			psels = <NRF_PSEL(TWIM_SDA, 0, 10)>,
					<NRF_PSEL(TWIM_SCL, 0, 7)>;
		};
	};

	i2c0_sleep: i2c0_sleep {
		group1 {
			psels = <NRF_PSEL(TWIM_SDA, 0, 10)>,
					<NRF_PSEL(TWIM_SCL, 0, 7)>;
			low-power-enable;
		};
	};

&i2c0 {
	compatible = "nordic,nrf-twim";
	status = "okay";
	clock-frequency = <400000>;
	zephyr,concat-buf-size = <512>;

	pinctrl-0 = <&i2c1_default>;
	pinctrl-1 = <&i2c1_sleep>;
	pinctrl-names = "default", "sleep";

	rv_8263_c8: rv-8263-c8@51 {
		compatible = "microcrystal,rv-8263-c8";
		reg = <0x51>;
		status = "okay";
		clkout = <1024>;
		int-gpios = <&gpio1 13 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;
	};
};
