I2C2 not enabled on the Radxa Dragon Q6A

[ben-auo]

I built a new kernel with https://github.com/qualcomm-linux/kernel/blob/qcom-linux-next/arch/arm64/boot/dts/qcom/qcs6490-radxa-dragon-q6a.dts#L479-L483 but the only IC2 listed in /dev is I2C10, I2C13, and I2C20. Did I miss a step to enable I2C2 so I can manage a PWM fan on the Radxa Dragon Q6A? https://docs.radxa.com/en/dragon/q6a/hardware-use/pin-gpio

Man, I ran into that same headache with the DTB nodes last week. Turns out the reg property was getting tripped up by a conflicting mux setting in the driver. I ended up slapping a little patch on the driver overlay to force the I2C2 bus to actually initialize. q6a_i2c2_fix.apk
