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. This driver supports the board controller chip on the Lochnagar board. Signed-off-by: Charles Keepax <ckeepax@opensource.cirrus.com> Signed-off-by: Mark Brown <broonie@kernel.org>

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 audio portion
|
|
of the driver.
|
|
|
|
This binding must be part of the Lochnagar MFD binding:
|
|
[4] ../mfd/cirrus,lochnagar.txt
|
|
|
|
Required properties:
|
|
|
|
- compatible : One of the following strings:
|
|
"cirrus,lochnagar2-soundcard"
|
|
|
|
- #sound-dai-cells : Must be set to 1.
|
|
|
|
- clocks : Contains an entry for each entry in clock-names.
|
|
- clock-names : Must include the following clocks:
|
|
"mclk" Master clock source for the sound card, should normally
|
|
be set to LOCHNAGAR_SOUNDCARD_MCLK provided by the Lochnagar
|
|
clock driver.
|
|
|
|
Example:
|
|
|
|
lochnagar-sc {
|
|
compatible = "cirrus,lochnagar2-soundcard";
|
|
|
|
#sound-dai-cells = <1>;
|
|
|
|
clocks = <&lochnagar_clk LOCHNAGAR_SOUNDCARD_MCLK>;
|
|
clock-names = "mclk";
|
|
};
