[PATCH v2 0/4] hw/sensor: Add new device emulation for TI ADC128D818

Posted by Emmanuel Blot 1 month, 1 week ago

This is a 12-bit, 8-channel ADC I2C device, which is used on several
OpenBMC platforms.

QOM properties can be used to change input ADC values and external VREF at
run time.

Add it to AST2600-based Anacapa machine, along with some functional tests
that use QOM properties to inject voltage values into analog inputs.
