--- v3->v4: - Add qspi node to dtsi based on alphabetical order - Add spi-tx-bus-width and spi-rx-bus-width
v2->v3: - Change flash compatible to "jedec,spi-nor" - Change spi-max-frequency to 100MHz --- arch/arm/dts/socfpga_stratix10.dtsi | 15 +++++++++++++++ arch/arm/dts/socfpga_stratix10_socdk.dts | 23 +++++++++++++++++++++++ 2 files changed, 38 insertions(+)
