Subject: [PATCH] arm64: dts: ls1028a: add flexspi nodes
|
|
|
|
Add fspi node property for LS1028A SoC for FlexSPI driver.
|
|
Property added for the FlexSPI controller and for the connected
|
|
slave device for the LS1028ARDB and LS1028AQDS target.
|
|
This is having one SPI-NOR flash device, mt35xu02g connected at
|
|
CS0.
