Nordic Board Information Configuration Registers (BICR)

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`ioport-power-rails`	`phandle-array`	Power supply configurations for GPIO ports. The configuration is board- specific and stored in BICR. The property is encoded as <&phandle rail>, where: - phandle is the phandle of the associated GPIO port - rail is the 8-bit power rail configuration to apply to the port
`ioport-drivectrls`	`phandle-array`	Drive control settings for GPIO ports. The configuration is board-specific and stored in BICR. The property is encoded as <&phandle resistance>, where: - phandle is the phandle of the associated GPIO port - resistance is the resistance in ohms to adjust in the port's drive control, and can be one of the following: [33, 40, 50, 66, 100].
`power-vddao5v0`	`string`	VDD_AO_5V0 power rail configuration. Legal values: `'external'`, `'shorted'`
`power-vddao1v8`	`string`	VDD_AO_1V8 power rail configuration. Legal values: `'internal'`, `'external'`
`power-vdd1v0`	`string`	VDD_1V0 power rail configuration. Legal values: `'internal'`, `'external'`
`power-vddrf1v0`	`string`	VDD_RF_1V0 power rail configuration. Legal values: `'external'`, `'shorted'`
`power-vddao0v8`	`string`	VDD_AO_0V8 power rail configuration. Legal values: `'internal'`, `'external'`
`power-vddvs0v8`	`string`	VDD_VS_0V8 power rail configuration. Legal values: `'internal'`, `'external'`
`inductor-present`	`boolean`	DC/DC inductor present.
`lfosc-accuracy`	`int`	LFXO crystal or external signal accuracy in ppm. Legal values: `500`, `250`, `150`, `100`, `75`, `50`, `30`, `20`
`lfosc-mode`	`string`	LFXO operational mode. Legal values: `'crystal'`, `'external-sine'`, `'external-square'`
`lfosc-loadcap`	`int`	Built-in load capacitors selection in 1pF steps, up to 25pF max. If 0, only external capacitors will be used.
`lfosc-startup`	`int`	LFXO startup time in milliseconds.
`lfrc-autocalibration`	`array`	A list of values pertaining to LFRC autocalibration settings. The prop is encoded as <temp-interval temp-delta interval-max-count>, where: - temp-interval is the temperature measurement interval in 0.25s steps - temp-delta is the temperature delta that should trigger a calibration in 0.25 degree steps - interval-max-count are the max number of temp-interval periods in between calibrations, independent of temperature changes.
`hfxo-mode`	`string`	HFXO operational mode. Legal values: `'crystal'`, `'external-square'`
`hfxo-loadcap`	`int`	Built-in load capacitors selection in 0.25 pF steps, up to 25.75 pF max. If 0, only external capacitors will be used.
`hfxo-startup`	`int`	HFXO startup time in milliseconds.

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 “nordic,nrf-bicr” compatible.

Name	Type	Details
`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.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
