There are 2 version of QSPI-IP, according to which controller registers sets can be big endian or little endian.There are some other minor changes like RX fifo depth etc.
The big endian version uses driver compatible "fsl,ls1021a-qspi" and little endian version uses driver compatible "fsl,ls2080a-qspi" Signed-off-by: Kuldeep Singh <kuldeep.si...@nxp.com> Signed-off-by: Ashish Kumar <ashish.ku...@nxp.com> Reviewed-by: Rob Herring <r...@kernel.org> Acked-by: Han Xu <han...@nxp.com> --- v4: -Rebase to spi.git, -Add new patch to series. -Previous versions reviewed here http://patchwork.ozlabs.org/patch/1118639/ v3: Rebase to top v2: Convert to patch series and rebasing done on top of tree Documentation/devicetree/bindings/spi/spi-fsl-qspi.txt | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/spi/spi-fsl-qspi.txt b/Documentation/devicetree/bindings/spi/spi-fsl-qspi.txt index e8f1d62..6d7c9ec 100644 --- a/Documentation/devicetree/bindings/spi/spi-fsl-qspi.txt +++ b/Documentation/devicetree/bindings/spi/spi-fsl-qspi.txt @@ -3,9 +3,8 @@ Required properties: - compatible : Should be "fsl,vf610-qspi", "fsl,imx6sx-qspi", "fsl,imx7d-qspi", "fsl,imx6ul-qspi", - "fsl,ls1021a-qspi" + "fsl,ls1021a-qspi", "fsl,ls2080a-qspi" or - "fsl,ls2080a-qspi" followed by "fsl,ls1021a-qspi", "fsl,ls1043a-qspi" followed by "fsl,ls1021a-qspi" - reg : the first contains the register location and length, the second contains the memory mapping address and length -- 2.7.4
