-Cirrus Logic Lochnagar Audio Development Board
-
-Lochnagar is an evaluation and development board for Cirrus Logic
-Smart CODEC and Amp devices. It allows the connection of most Cirrus
-Logic devices on mini-cards, as well as allowing connection of
-various application processor systems to provide a full evaluation
-platform. Audio system topology, clocking and power can all be
-controlled through the Lochnagar, allowing the device under test
-to be used in a variety of possible use cases.
-
-This binding document describes the binding for the regulator portion
-of the driver.
-
-Also see these documents for generic binding information:
- [1] Regulator: ../regulator/regulator.txt
-
-This binding must be part of the Lochnagar MFD binding:
- [2] ../mfd/cirrus,lochnagar.txt
-
-Optional sub-nodes:
-
- - VDDCORE : Initialisation data for the VDDCORE regulator, which
- supplies the CODECs digital core if it has no build regulator for that
- purpose.
- Required Properties:
- - compatible : One of the following strings:
- "cirrus,lochnagar2-vddcore"
- - SYSVDD-supply: Primary power supply for the Lochnagar.
-
- - MICVDD : Initialisation data for the MICVDD regulator, which
- supplies the CODECs MICVDD.
- Required Properties:
- - compatible : One of the following strings:
- "cirrus,lochnagar2-micvdd"
- - SYSVDD-supply: Primary power supply for the Lochnagar.
-
- - MIC1VDD, MIC2VDD : Initialisation data for the MICxVDD supplies.
- Required Properties:
- - compatible : One of the following strings:
- "cirrus,lochnagar2-mic1vdd", "cirrus,lochnagar2-mic2vdd"
- Optional Properties:
- - cirrus,micbias-input : A property selecting which of the CODEC
- minicard micbias outputs should be used, valid values are 1 - 4.
- - MICBIAS1-supply, MICBIAS2-supply: Regulator supplies for the
- MICxVDD outputs, supplying the digital microphones, normally
- supplied from the attached CODEC.
-
- - VDD1V8 : Recommended fixed regulator for the VDD1V8 regulator, which supplies the
- CODECs analog and 1.8V digital supplies.
- Required Properties:
- - compatible : Should be set to "regulator-fixed"
- - regulator-min-microvolt : Should be set to 1.8V
- - regulator-max-microvolt : Should be set to 1.8V
- - regulator-boot-on
- - regulator-always-on
- - vin-supply : Should be set to same supply as SYSVDD
-
-Example:
-
-lochnagar {
- lochnagar-micvdd: MICVDD {
- compatible = "cirrus,lochnagar2-micvdd";
-
- SYSVDD-supply = <&wallvdd>;
-
- regulator-min-microvolt = <3300000>;
- regulator-max-microvolt = <3300000>;
- };
-
- lochnagar-vdd1v8: VDD1V8 {
- compatible = "regulator-fixed";
-
- regulator-name = "VDD1V8";
- regulator-min-microvolt = <1800000>;
- regulator-max-microvolt = <1800000>;
- regulator-boot-on;
- regulator-always-on;
-
- vin-supply = <&wallvdd>;
