The output voltage of a voltage controlled regulator can be controlled
through the voltage of another regulator. A vctrl regulator can be
continuous or discrete, depending on its control regulator. The current
version of this driver assumes that the output voltage is a linear
function of the contro

The new function allows consumers to determine if a regulator is
continuous or discrete, and whether the results of
regulator_count_voltages() and regulator_list_voltage() correspond
to the regulator itself or its supply.

IDT 89HPESxNTx device series is PCIe-switches, which support

IDT NT-functions can be now supported in the kernel. This driver adds

Dear mm folks,
Are you OK with this change? I need a hook to when the init sections
