The clock speed in Hz. Ranges from 100000 (100 kHz) to
5000000 (5 Mhz). I2C busses that involve external wires may
have to be slower, and the real maximum speed the bus will
support depends on the value of the pullup resistors and the
design of the overall circuit.

config I2C_MANAGER_0_PULLUPS
bool "Use ESP32 built-in bus pull-up resistors"
help
The I2C bus needs resistors to make sure it's in a defined
state when nobody is talking. Many circuits have external
pullup resistors already and turning these on will increase
power consumption slightly and may limit the speed your bus
can attain. Try with these off first if you don't know.
