Subject: Re: [PATCH 5/5] ASoC: cs34l45: Hibernation support
Date: Thu, 2 Mar 2023 11:59:05 -0600	[thread overview]
Message-ID: <6f34d2c8-21b5-5b75-a3cd-15f88ba0f760@opensource.cirrus.com> (raw)
In-Reply-To: <8aef2c0c-9bd0-4c3a-86e1-7732ddedabfd@sirena.org.uk>

The CS35L45 features a low-power Hibernation State. In this state, all 
register contents are lost, but the contents of
RAM are retained. In the Hibernation State, only always-on digital 
functions to support wake-up are enabled.
Entry to this state is achieved via the register interface (either by an 
external driver using the control port, or the
programmable DSP). Exit from this state is triggered by activity on 
device GPIO pins, intended SPI transaction, or I2C
transaction with intended slave address
