[U-Boot] [PATCH 09/47] Drop digital thermometer and thermostat (DTT) drivers

Simon Glass
2017-05-15T10:57:24Z

This subsystem is quite old. It has been replaced with a driver-model
version (UCLASS_THERMAL). Boards are free to convert to that if required,
but here is a removal patch that could be applied in the meantime.
