renesas,rcar-mmc

Note

An implementation of a driver matching this compatible is available in drivers/sdhc/rcar_mmc.c.

Description

These nodes are “sd” bus nodes.

Renesas R-Car eMMC

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`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.
`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. This property is required. Default value: `400000`
`non-removable`	`boolean`	Non-removable slots (like eMMC), which are assumed to always be present, will affect the `sdhc_card_present` call. This call will always return true if this property exists for the node.
`mmc-sdr104-support`	`boolean`
`cd-gpios`	`phandle-array`	Card Detect pin
`pwr-gpios`	`phandle-array`	Power pin
`vmmc-supply`	`phandle`	Supply for the card power
`vqmmc-supply`	`phandle`	Supply for the bus IO line power, such as a level shifter. If the level shifter is controlled by a GPIO line, this shall be modeled as a "regulator-fixed" with a GPIO line for switching the level shifter on/off.
`bus-width`	`int`	Bus width for SDMMC access, defaults to the minimum necessary number of bus lines Default value: `1` Legal values: `1`, `4`, `8`
`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.
`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
`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.
`resets`	`phandle-array`	Reset information
`reset-names`	`string-array`	Name of each reset

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 “renesas,rcar-mmc” compatible.

Name	Type	Details
`clocks`	`phandle-array`	Clock gate information This property is required.
`reg`	`array`	register space This property is required. See Important properties for more information.
`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-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.
`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
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`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.
