-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 clock portion of
-the driver.
-
-Also see these documents for generic binding information:
- [1] Clock : ../clock/clock-bindings.txt
-
-And these for relevant defines:
- [2] include/dt-bindings/clock/lochnagar.h
-
-This binding must be part of the Lochnagar MFD binding:
- [3] ../mfd/cirrus,lochnagar.txt
-
-Required properties:
-
- - compatible : One of the following strings:
- "cirrus,lochnagar1-clk"
- "cirrus,lochnagar2-clk"
-
- - #clock-cells : Must be 1. The first cell indicates the clock
- number, see [2] for available clocks and [1].
-
-Optional properties:
-
- - clocks : Must contain an entry for each clock in clock-names.
- - clock-names : May contain entries for each of the following
- clocks:
- - ln-cdc-clkout : Output clock from CODEC card.
- - ln-dsp-clkout : Output clock from DSP card.
- - ln-gf-mclk1,ln-gf-mclk2,ln-gf-mclk3,ln-gf-mclk4 : Optional
- input audio clocks from host system.
- - ln-psia1-mclk, ln-psia2-mclk : Optional input audio clocks from
- external connector.
- - ln-spdif-mclk : Optional input audio clock from SPDIF.
- - ln-spdif-clkout : Optional input audio clock from SPDIF.
- - ln-adat-mclk : Optional input audio clock from ADAT.
- - ln-pmic-32k : On board fixed clock.
- - ln-clk-12m : On board fixed clock.
- - ln-clk-11m : On board fixed clock.
- - ln-clk-24m : On board fixed clock.
- - ln-clk-22m : On board fixed clock.
- - ln-clk-8m : On board fixed clock.
- - ln-usb-clk-24m : On board fixed clock.
- - ln-usb-clk-12m : On board fixed clock.
-
- - assigned-clocks : A list of Lochnagar clocks to be reparented, see
- [2] for available clocks.
- - assigned-clock-parents : Parents to be assigned to the clocks
- listed in "assigned-clocks".
-
-Optional nodes:
-
- - fixed-clock nodes may be registered for the following on board clocks:
- - ln-pmic-32k : 32768 Hz
- - ln-clk-12m : 12288000 Hz
- - ln-clk-11m : 11298600 Hz
- - ln-clk-24m : 24576000 Hz
- - ln-clk-22m : 22579200 Hz
- - ln-clk-8m : 8192000 Hz
- - ln-usb-clk-24m : 24576000 Hz
- - ln-usb-clk-12m : 12288000 Hz
-
-Example:
-
-lochnagar {
- lochnagar-clk {
- compatible = "cirrus,lochnagar2-clk";
-
- #clock-cells = <1>;
-
- clocks = <&clk-audio>, <&clk_pmic>;
