st,stm32-qspi¶

Description¶

These nodes are “qspi” bus nodes.

STM32 QSPI device representation. A stm32 quadspi node would typically
looks to this:

    &quadspi {
        pinctrl-0 = <&quadspi_clk_pe10 &quadspi_ncs_pe11
                     &quadspi_bk1_io0_pe12 &quadspi_bk1_io1_pe13
                     &quadspi_bk1_io2_pe14 &quadspi_bk1_io3_pe15>;

        dmas = <&dma1 5 5 0x0000 0x03>;
        dma-names = "tx_rx";

        status = "okay";
    };

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`pinctrl-0`	`phandles`	This property is required.

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-qspi” 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.
`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. For example dmas for TX/RX on QSPI dmas = <&dma1 5 5 0x0000 0x03>;
`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.
`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
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
