Even though the qspi2 can't come under any associated spi nor flash it would require to specify the same to make proper binding happen for other spi slaves. > > Signed-off-by: Jagan Teki <jagan at amarulasolutions.com> > Reviewed-by: Bin Meng <bmeng.cn at gmail.com> Acked-by: Rick Chen <rick at andestech.com> > --- > Changes for v4: > - update licence > > arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi | 10 ++++++++++ > 1 file changed, 10 insertions(+) > create mode 100644 arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi > > diff --git a/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi b/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi > new file mode 100644 > index 0000000000..8a784b5661 > --- /dev/null > +++ b/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi > @@ -0,0 +1,10 @@ > +// SPDX-License-Identifier: (GPL-2.0 OR MIT) > +/* > + * Copyright (C) 2019 Jagan Teki <jagan at amarulasolutions.com> */ > + > +/ { > + aliases { > + spi2 = &qspi2; > + }; > +}; > -- > 2.17.1 >
