stm32 sdmmc disk access

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.
`cd-gpios`	`phandle-array`	Card Detect pin
`pwr-gpios`	`phandle-array`	Power pin
`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`
`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.

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,stm32-sdmmc” 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.
`dmas`	`phandle-array`	Optional DMA channel specifier. If DMA should be used, specifier should hold a phandle reference to the dma controller, the channel number, the slot number, channel configuration and finally features. Only priority bits are used in the configuration. There are no feature flags. For example dmas for TX/RX on SDMMC dmas = <&dma2 4 6 0x30000 0x00>, <&dma2 4 3 0x30000 0x00>;
`dma-names`	`string-array`	DMA channel name. If DMA should be used, expected value is "tx", "rx". For example dma-names = "tx", "rx";
`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
`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.
