ADC 1 and 2 prescaler
- 0: Disables the clock so the ADC can use AHB clock (synchronous mode)
- Other values n: The ADC can use the PLL clock divided by n
On STM32F37x, only 2/4/6/8 are allowed.
Legal values: |
|
|
ADC 3 and 4 prescaler
- 0: Disables the clock so the ADC can use AHB clock (synchronous mode)
- Other values n: The ADC can use the PLL clock divided by n
Check RefMan for availability.

|
default frequency in Hz for clock output
This property is required. |

|
AHB prescaler. Defines actual core clock frequency (HCLK)
based on system frequency input.
The HCLK clocks CPU, AHB, memories and DMA.

On some parts, it could be required to set up highest core frequencies
(>80MHz) in two steps in order to prevent undershoot.
This is done by applying an intermediate AHB prescaler before switching
System Clock source to PLL. Once done, prescaler is set back to expected
value.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
