RK3399 has rst_pulse_length in CONTROL_REG[4:2], determining the length
of pulse to issue for system reset. We shouldn't clobber this value,
because that might make the system reset ineffective. On RK3399, we're
seeing that a value of 000b (meaning 2 cycles) yields an unreliable
(partial?) reset, a

Currently the filter logic creates a binary search tree (with some

Purpose of having pinctrl dapm is to dynamically put the pins in
low power state when they are not actively used by the audio and

Without this each driver has to set the pinctrl states, either

The pred_funcs_##type arrays consist of five functions that are assigned

Instead of having a separate enum that is the index into another array, like
a string array, make a single macro that combines them into a single list,
and then the two can not get out of sync. This makes it easier to add and
remove items.
The macro trick is:
