ARM: DTS: stm32: add stm32f746-disco device tree files
This patch adds the DTS source files needed for stm32f746-disco board The files are based on the stm32f429/469 files from current linux kernel.

STM32 QSPI controller device tree bindings
|
||||
--------------------------------------------
|
||||
|
||||
Required properties:
|
||||
- compatible : should be "st,stm32-qspi".
|
||||
- reg : 1. Physical base address and size of SPI registers map.
|
||||
2. Physical base address & size of mapped NOR Flash.
|
||||
- spi-max-frequency : Max supported spi frequency.
|
||||
- status : enable in requried dts.
|
||||
|
||||
Connected flash properties
|
||||
--------------------------
|
||||
- spi-max-frequency : Max supported spi frequency.
|
||||
- spi-tx-bus-width : Bus width (number of lines) for writing (1-4)
|
||||
- spi-rx-bus-width : Bus width (number of lines) for reading (1-4)
|
||||
- memory-map : Address and size for memory-mapping the flash
|
||||
|
||||
Example:
|
||||
qspi: quadspi@A0001000 {
|
||||
compatible = "st,stm32-qspi";
|
||||
#address-cells = <1>;

|
||||
interrupts = <92>;
|
||||
spi-max-frequency = <108000000>;
|

#address-cells = <1>;
|
||||
#size-cells = <1>;
|
||||

|
||||
spi-max-frequency = <108000000>;
|
||||
spi-tx-bus-width = <4>;
|
||||
spi-rx-bus-width = <4>;
|
