Hello Konrad, This frequency value is used in the vendor kernel [1], hence why I used it. I did a test at 400 kHz, and the I2C devices (touchscreen here, and NFC in the other patch) are still detected, with basic functions still working. Let me know if I should still update to use 400 kHz. I would prefer to keep the value from the vendor kernel (and in that case, I will update the commit message to add that information). Thanks Alex [1] https://github.com/LineageOS/android_kernel_htc_msm8974/blob/lineage-18.1/arch/arm/boot/dts/msm8974.dtsi#L970 > > Konrad > >
