Merge branches 'clk-ingenic-fixes', 'clk-max9485', 'clk-pxa-32k-pll', 'clk-aspeed' and 'clk-imx6sll-gpio' into clk-next
* clk-ingenic-fixes: : - Ingenic i2s bit update and allow UDC clk to gate clk: ingenic: Add missing flag for UDC clock clk: ingenic: Fix incorrect data for the i2s clock * clk-max9485: : - Maxim 9485 Programmable Clock Generator clk: Add driver for MAX9485 dts: clk: add devicetree bindings for MAX9485 * clk-pxa-32k-pll: : - Expose 32 kHz PLL on PXA SoCs clk: pxa: export 32kHz PLL * clk-aspeed: : - Fix name of aspeed SDC clk define to have only one 'CLK' clk: aspeed: Fix SDCLK name * clk-imx6sll-gpio: : - imx6sll GPIO clk gate support clk: imx6sll: add GPIO LPCGs

Devicetree bindings for Maxim MAX9485 Programmable Audio Clock Generator
|
||||
|
||||
This device exposes 4 clocks in total:
|
||||
|
||||
- MAX9485_MCLKOUT: A gated, buffered output of the input clock of 27 MHz
|
||||
- MAX9485_CLKOUT: A PLL that can be configured to 16 different discrete
|
||||
frequencies
|
||||
- MAX9485_CLKOUT[1,2]: Two gated outputs for MAX9485_CLKOUT
|
||||
|
||||
MAX9485_CLKOUT[1,2] are children of MAX9485_CLKOUT which upchain all rate set
|
||||
requests.
|
||||
|
||||
Required properties:
|
||||
- compatible: "maxim,max9485"
|
||||
- clocks: Input clock, must provice 27.000 MHz
|
||||
- clock-names: Must be set to "xclk"
|
||||
- #clock-cells: From common clock binding; shall be set to 1
|
||||
|
||||
Optional properties:
|
||||
- reset-gpios: GPIO descriptor connected to the #RESET input pin
|
||||
- vdd-supply: A regulator node for Vdd
|
||||
- clock-output-names: Name of output clocks, as defined in common clock
|
||||
bindings
|
||||
|
||||
If not explicitly set, the output names are "mclkout", "clkout", "clkout1"
|
||||
and "clkout2".
|
||||
|
||||
Clocks are defined as preprocessor macros in the dt-binding header.
|
||||
|
||||
Example:
|
||||
|
||||
#include <dt-bindings/clock/maxim,max9485.h>
|
||||
|
||||
xo-27mhz: xo-27mhz {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <27000000>;
|
||||
};
|
||||
|
||||
&i2c0 {
|
||||
max9485: audio-clock@63 {
|
||||
reg = <0x63>;
|
||||
compatible = "maxim,max9485";
|
||||
clock-names = "xclk";
|
||||
clocks = <&xo-27mhz>;
|
||||
reset-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
|
||||
vdd-supply = <&3v3-reg>;
|
||||
#clock-cells = <1>;
|
||||
};
|
||||
};
|
||||
|
||||
// Clock consumer node
|
||||
|
||||
foo@0 {
|
||||
compatible = "bar,foo";
|
||||
/* ... */
|
||||
clock-names = "foo-input-clk";
|
||||
clocks = <&max9485 MAX9485_CLKOUT1>;
|
||||
};
