st,stm32f105-pll2-clock

Vendor: STMicroelectronics N.V.

Description

PLL2 node binding for Connectivity line devices (STM32F105/STM32F107)

Takes clk_hse as input clock, using prediv as prescaler.

Each PLL as its own output clock.

  f(PLL2CLK) = f(PLL2IN) / PREDIV * PLLMUL --> PLL (System Clock)

This property is required.

otgfspre

boolean

Optional PLL output divisor to generate a 48MHz USB clock.
When set, PLL output clock is not divided.
Otherwise, PLL output clock is divided by 1.5.

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “st,stm32f105-pll2-clock” compatible.

zephyr,deferred-init

boolean

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

wakeup-source

boolean

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.

zephyr,pm-device-runtime-auto

boolean

Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

List of power states that will disable this device power.
