| |
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.
