Risc-V Linux, DTS interrupt PIN for MPU6050 driver

I’m connecting the MPU6050 to my RISC-V milkv duo board after compiling in the built-in driver. I get the following in dmesg:

[    0.805674] inv-mpu6050-i2c 0-0068: mounting matrix not found: using identity...
[    0.813447] inv-mpu6050-i2c 0-0068: Could not find IRQ 0
[    0.819145] inv-mpu6050-i2c: probe of 0-0068 failed with error -22

# i2cdetect -ry 0
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- 56 -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --

I’m connecting the Interrupt pin to GPIOA26 and using the following DTS:

&i2c0 {
       status = "okay";
       clock-frequency = <100000>;
       mpu6050@68 {
        compatible = "invensense,mpu6050";
        reg = <0x68>;
        interrupt-parent = <&gpio0>;
        interrupts = <26 IRQ_TYPE_EDGE_RISING>;
    };
};

What is the correct values for interrupt-parent and interrupts?
