Add bindings information for STM32 Timers version 6: - rename stm32-gtimer to stm32-timers - change compatible - add description about the IPs version 2: - rename stm32-mfd-timer to stm32-gptimer - only keep one compatible string Signed-off-by: Benjamin Gaignard <benjamin.gaignard@xxxxxx> --- .../devicetree/bindings/mfd/stm32-timers.txt | 46 ++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/stm32-timers.txt diff --git a/Documentation/devicetree/bindings/mfd/stm32-timers.txt b/Documentation/devicetree/bindings/mfd/stm32-timers.txt new file mode 100644 index 0000000..b30868e --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/stm32-timers.txt @@ -0,0 +1,46 @@ +STM32 Timers driver bindings + +This IP provides 3 types of timer along with PWM functionality: +- advanced-control timers consist of a 16-bit auto-reload counter driven by a programmable + prescaler, break input feature, PWM outputs and complementary PWM ouputs channels. +- general-purpose timers consist of a 16-bit or 32-bit auto-reload counter driven by a + programmable prescaler and PWM outputs. +- basic timers consist of a 16-bit auto-reload counter driven by a programmable prescaler. + +Required parameters: +- compatible: must be "st,stm32-timers" + +- reg: Physical base address and length of the controller's + registers. +- clock-names: Set to "clk_int". +- clocks: Phandle to the clock used by the timer module. + For Clk properties, please refer to ../clock/clock-bindings.txt + +Optional parameters: +- resets: Phandle to the parent reset controller. + See ../reset/st,stm32-rcc.txt + +Optional subnodes: +- pwm: See ../pwm/pwm-stm32.txt +- timer: See ../iio/timer/stm32-timer-trigger.txt + +Example: + timers@40010000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "st,stm32-timers"; + reg = <0x40010000 0x400>; + clocks = <&rcc 0 160>; + clock-names = "clk_int"; + + pwm { + compatible = "st,stm32-pwm"; + pinctrl-0 = <&pwm1_pins>; + pinctrl-names = "default"; + }; + + timer { + compatible = "st,stm32-timer-trigger"; + reg = <0>; + }; + }; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
