Properties

Properties not inherited from the base binding file.

Name

Type

Details

core-clock-div

int

Divide 96 MHz PLL clock to produce Cortex-M4 core clock

This property is required.

slow-clock-div

int

PWM and TACH clock domain divided down from 48 MHz AHB clock. The
default value is 480 for 100 kHz.

pll-32k-src

int

32 KHz clock source for PLL

This property is required.

periph-32k-src

int

32 KHz clock source for peripherals

This property is required.

xtal-single-ended

boolean

Use single ended crystal connection to XTAL2 pin.

clk32kmon-period-min

int

32KHz clock monitor minimum valid 32KHz period in 48MHz units

This property is required.

clk32kmon-period-max

int

32KHz clock monitor maximum valid 32KHz period in 48MHz units

This property is required.

clk32kmon-duty-cycle-var-max

int

Maximum duty cycle variation. Difference in units of 48HMz between
the measured 32KHz high and low pulse widths.

This property is required.

clk32kmon-valid-min

int

Mininum number of consecutive 32KHz pulses that pass all monitor tests

This property is required.

xtal-enable-delay-ms

int

Delay in milliseconds after crystal is enabled and clock monitor is
started.

This property is required.

Default value: 300

pll-lock-timeout-ms

int

Timeout in milliseconds waiting for PLL to lock to new clock source.

This property is required.

Default value: 30

clkmon-bypass

boolean

Bypass clkmon check of crystal or XTAL2 single-ended clock.

internal-osc-disable

boolean

If the internal silicon 32KHz oscillator is not chosen as the source
for PLL and Periheral devices then disable the internal 32KHz
oscillator to save power.

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

This property is required.

#clock-cells

int

Number of items to expect in a Clock specifier

This property is required.

Constant value: 3

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.
