What is the Jetson Nano I2C bus speed?

There are 2 I2C buses on the Jetson Nano. Does anyone know what speed they are configured for?

I have decompiled the device tree to a .dts file but it is not obvious what the frequency is there for each of the buses.

Thanks.

You should be able find “clock-frequency” for the i2c speed configure.

Okay, I had a look and found this for I2C dev 0:

i2c@7000c000 {
#address-cells = <0x1>;
#size-cells = <0x0>;
compatible = “nvidia,tegra210-i2c”;
reg = <0x0 0x7000c000 0x0 0x100>;
interrupts = <0x0 0x26 0x4>;
iommus = <0x2b 0xe>;
status = “okay”;
clock-frequency = <0x61a80>;

i.e. 400kHz.

Thanks.
