intel,emmc-host

Description

These nodes are “sd” bus nodes.

eMMC host controller

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`max-current-330`	`int`	Max drive current in mA at 3.3V. A value of zero indicates no maximum is specified by the driver.
`max-current-300`	`int`	Max drive current in mA at 3.0V. A value of zero indicates no maximum is specified by the driver.
`max-current-180`	`int`	Max drive current in mA at 1.8V. A value of zero indicates no maximum is specified by the driver.
`max-bus-freq`	`int`	Maximum bus frequency for SD card. This should be the highest frequency the SDHC is capable of negotiating with cards on the bus. Default value: `400000`
`min-bus-freq`	`int`	Minimum bus frequency for SD card. This should be the frequency that cards first will select when attached to the SDHC bus Default value: `400000`
`power-delay-ms`	`int`	time in ms for SDHC to delay when toggling power to the SD card. This delay gives the card time to power up or down fully Default value: `500`
`mmc-hs200-1_8v`	`boolean`	The host controller supports HS200 at 1.8V
`mmc-hs400-1_8v`	`boolean`	The host controller supports HS400 at 1.8V
`vendor-id`	`int`	Vendor ID of the device
`device-id`	`int`	Device ID of the device
`class-rev`	`int`	Optional class/revision register filter
`class-rev-mask`	`int`	Class/revision register mask

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 “intel,emmc-host” compatible.

Name	Type	Details
`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
`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.
