| 2 | |
| 3 | Palmas device has two clock output pins for 32KHz, KG and KG_AUDIO. |
| 4 | |
| 5 | This binding uses the common clock binding ./clock-bindings.txt. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible : "ti,palmas-clk32kg" for clk32kg clock |
| 9 | "ti,palmas-clk32kgaudio" for clk32kgaudio clock |
| 10 | - #clock-cells : shall be set to 0. |
| 11 | |
| 12 | Optional property: |
| 13 | - ti,external-sleep-control: The external enable input pins controlled the |
| 14 | enable/disable of clocks. The external enable input pins ENABLE1, |
| 15 | ENABLE2 and NSLEEP. The valid values for the external pins are: |
| 16 | PALMAS_EXT_CONTROL_PIN_ENABLE1 for ENABLE1 pin |
| 17 | PALMAS_EXT_CONTROL_PIN_ENABLE2 for ENABLE2 pin |
| 18 | PALMAS_EXT_CONTROL_PIN_NSLEEP for NSLEEP pin |
| 19 | Option 0 or missing this property means the clock is enabled/disabled |
| 20 | via register access and these pins do not have any control. |
| 21 | The macros of external control pins for DTS is defined at |
| 22 | dt-bindings/mfd/palmas.h |
| 23 | |
| 24 | Example: |
| 25 | #include <dt-bindings/mfd/palmas.h> |
| 26 | ... |
| 27 | palmas: tps65913@58 { |
| 28 | ... |
| 29 | clk32kg: palmas_clk32k@0 { |
| 30 | compatible = "ti,palmas-clk32kg"; |
| 31 | #clock-cells = <0>; |
| 32 | ti,external-sleep-control = <PALMAS_EXT_CONTROL_PIN_NSLEEP>; |
| 33 | }; |
| 34 | ... |
| 35 | }; |
