[PATCH 0/2] ASoC: cs35l45: Adds support for LDPM feature

[Ricardo Rivera-Matos]

The CS35L45 has an input signal level dependent power
management (LDPM) feature. The feature is used to reduce
power consumption when the amplifier is playing sustained
low amplitude audio. This feature is made up of two
responding groups each with a distinct threshold level and
entry time delay.

Group 1 can issue a low power request to either or both the
integrated boost converter and amplifier output stage
functional blocks.

Group 2 can issue a low power request to either or both the
VMON and IMON functional blocks.

This patch series introduces support for this feature as
devicetree properties applied at boot time.
