st,stm32-ospi

Description

These nodes are “ospi” bus nodes.

STM32 OSPI device representation. Enabling a stm32 octospi node in a board
description would typically requires this:

    &octospi {
        pinctrl-0 = <&octospi_clk_pe9 &octospi_ncs_pe10 &octospi_dqs_pe11
                     &octospi_io0_pe12 &octospi_io1_pe13
                     &octospi_io2_pe14 &octospi_io3_pe15
                     &octospi_io4_pe16 &octospi_io5_pe17
                     &octospi_io6_pe18 &octospi_io7_pe19>;

        dmas = <&dma1 5 41 0x10000>;
        dma-names = "tx_rx";

        status = "okay";
    };

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.
`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-ospi” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`clock-names`	`string-array`	name of each clock This property is required.
`dmas`	`phandle-array`	Optional DMA channel specifier, required for DMA transactions. For example dmas for TX/RX on OSPI dmas = <&dma1 5 41 0x10000>; With, in each cell of the dmas specifier: - &dma1: dma controller phandle - 5: channel number (0 to Max-Channel minus 1). From 0 to 15 on stm32u5x. - 41: slot number (request which could be given by the DMAMUX) - 0x10000: channel configuration (only for srce/dest data size, priority) Notes: - On series supporting DMAMUX, the DMA phandle should be provided but DMAMUX node should also be enabled in the DTS. - For channel configuration, only the config bits priority and periph/mem datasize are used. The periph/mem datasize must be equal, 0 is a correct value. - There is no Fifo used by this DMA peripheral. For example dmas for TX/RX on OSPI dmas = <&dma1 5 41 0x10000>;
`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-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
`#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.
