Subject: mt6370 i2c error -ETIMEDOUT: Failed to check vendor info

I can't seem to get the device registered. I have the device in an I2c
node just like in the documentation

DTS code

&i2c2 {
        compatible = "mediatek,mt8186-i2c";
        &pmic@34 {
                compatible = "mediatek,mt6370";
        }
};

It seems to time out during probe.
          regmap_read(rmap, MT6370_REG_DEV_INFO, &devinfo);
returns -110
