Define bindings for STM32 timer trigger version 4: - remove triggers enumeration from DT - add reg parameter version 3: - change file name - add cross reference with mfd bindings version 2: - only keep one compatible - add DT parameters to set lists of the triggers: one list describe the triggers created by the device another one give the triggers accepted by the device Signed-off-by: Benjamin Gaignard <redacted> --- .../bindings/iio/timer/stm32-timer-trigger.txt | 23 ++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/timer/stm32-timer-trigger.txtdiff --git a/Documentation/devicetree/bindings/iio/timer/stm32-timer-trigger.txt b/Documentation/devicetree/bindings/iio/timer/stm32-timer-trigger.txt new file mode 100644 index 0000000..36a6c4a --- /dev/null +++ b/Documentation/devicetree/bindings/iio/timer/stm32-timer-trigger.txt@@ -0,0 +1,23 @@ +STMicroelectronics STM32 Timers IIO timer bindings + +Must be a sub-node of an STM32 Timers device tree node. +See ../mfd/stm32-timers.txt for details about the parent node. + +Required parameters: +- compatible: Must be "st,stm32-timer-trigger". +- reg: Define triggers configuration of the hardware IP.
Valid values? Not sure this makes sense for use of reg. reg should be how you address or id a device.

+Example:
+ timers@40010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "st,stm32-timers";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "clk_int";
+
+ timer {This would also need an unit address.
+ compatible = "st,stm32-timer-trigger"; + reg = <0>; + }; + }; -- 1.9.1
