* Atmel Quad Serial Peripheral Interface (QSPI) |
|
|
|
Required properties: |
|
- compatible: Should be one of the following: |
|
- "atmel,sama5d2-qspi" |
|
- "microchip,sam9x60-qspi" |
|
- reg: Should contain the locations and lengths of the base registers |
|
and the mapped memory. |
|
- reg-names: Should contain the resource reg names: |
|
- qspi_base: configuration register address space |
|
- qspi_mmap: memory mapped address space |
|
- interrupts: Should contain the interrupt for the device. |
|
- clocks: Should reference the peripheral clock and the QSPI system |
|
clock if available. |
|
- clock-names: Should contain "pclk" for the peripheral clock and "qspick" |
|
for the system clock when available. |
|
- #address-cells: Should be <1>. |
|
- #size-cells: Should be <0>. |
|

|
|
