-Binding for Maxim MAX77686/MAX77802/MAX77620 32k clock generator block
-
-This is a part of device tree bindings of MAX77686/MAX77802/MAX77620
-multi-function device. More information can be found in MFD DT binding
-doc as follows:
- bindings/mfd/max77686.txt for MAX77686 and
- bindings/mfd/max77802.txt for MAX77802 and
- bindings/mfd/max77620.txt for MAX77620.
-
-The MAX77686 contains three 32.768khz clock outputs that can be controlled
-(gated/ungated) over I2C. Clocks are defined as preprocessor macros in
-dt-bindings/clock/maxim,max77686.h.
-
-
-The MAX77802 contains two 32.768khz clock outputs that can be controlled
-(gated/ungated) over I2C. Clocks are defined as preprocessor macros in
-dt-bindings/clock/maxim,max77802.h.
-
-The MAX77686 contains one 32.768khz clock outputs that can be controlled
-(gated/ungated) over I2C. Clocks are defined as preprocessor macros in
-dt-bindings/clock/maxim,max77620.h.
-
-Following properties should be presend in main device node of the MFD chip.
-
-Required properties:
-
-- #clock-cells: from common clock binding; shall be set to 1.
-
-Optional properties:
-- clock-output-names: From common clock binding.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. Following indices are allowed:
- - 0: 32khz_ap clock (max77686, max77802), 32khz_out0 (max77620)
- - 1: 32khz_cp clock (max77686, max77802),
- - 2: 32khz_pmic clock (max77686).
-
-Clocks are defined as preprocessor macros in above dt-binding header for
-respective chips.
-
-Example:
-
-1. With MAX77686:
-
-#include <dt-bindings/clock/maxim,max77686.h>
-/* ... */
-
- Node of the MFD chip
- max77686: max77686@9 {
- compatible = "maxim,max77686";
- interrupt-parent = <&wakeup_eint>;
- interrupts = <26 IRQ_TYPE_LEVEL_LOW>;
- reg = <0x09>;
- #clock-cells = <1>;
-
- /* ... */
- };
-
- Clock consumer node
-
- foo@0 {
- compatible = "bar,foo";
- /* ... */
- clock-names = "my-clock";
- clocks = <&max77686 MAX77686_CLK_PMIC>;
- };
-
-2. With MAX77802:
-
-#include <dt-bindings/clock/maxim,max77802.h>
-/* ... */
-
- Node of the MFD chip
- max77802: max77802@9 {
- compatible = "maxim,max77802";
- interrupt-parent = <&wakeup_eint>;
- interrupts = <26 IRQ_TYPE_LEVEL_LOW>;
- reg = <0x09>;
- #clock-cells = <1>;
-
- /* ... */
- };
-
- Clock consumer node
-
- foo@0 {
- compatible = "bar,foo";
- /* ... */
- clock-names = "my-clock";
- clocks = <&max77802 MAX77802_CLK_32K_AP>;
- };
-
-
-3. With MAX77620:
-
-#include <dt-bindings/clock/maxim,max77620.h>
-/* ... */
-
- Node of the MFD chip
- max77620: max77620@3c {
- compatible = "maxim,max77620";
- reg = <0x3c>;
- #clock-cells = <1>;
- /* ... */
- };
-
- Clock consumer node
-
- foo@0 {
- compatible = "bar,foo";
- /* ... */
- clock-names = "my-clock";
- clocks = <&max77620 MAX77620_CLK_32K_OUT0>;
- };
