The spi0 controller on the A20 have up to 4 CS (Chip Select) while the others three only have 1. Add the num-cs property to each node. The current driver doesn't read this property but this is useful for downstream user of DTS (FreeBSD for example). Signed-off-by: Emmanuel Vadot <manu@bidouilliste.com> --- Changes in v3: * Put number in bracket Changes in v2: * Explain that driver doesn't support this but that it is useful for downstream users of DTS. arch/arm/boot/dts/sun7i-a20.dtsi | 4 ++++ 1 file changed, 4 insertions(+)
