^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) Palmas device has two clock output pins for 32KHz, KG and KG_AUDIO.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) This binding uses the common clock binding ./clock-bindings.txt.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - compatible : "ti,palmas-clk32kg" for clk32kg clock
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) "ti,palmas-clk32kgaudio" for clk32kgaudio clock
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - #clock-cells : shall be set to 0.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) Optional property:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - ti,external-sleep-control: The external enable input pins controlled the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) enable/disable of clocks. The external enable input pins ENABLE1,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) ENABLE2 and NSLEEP. The valid values for the external pins are:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) PALMAS_EXT_CONTROL_PIN_ENABLE1 for ENABLE1 pin
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) PALMAS_EXT_CONTROL_PIN_ENABLE2 for ENABLE2 pin
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) PALMAS_EXT_CONTROL_PIN_NSLEEP for NSLEEP pin
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Option 0 or missing this property means the clock is enabled/disabled
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) via register access and these pins do not have any control.
