We do set_speed even before this, during spi_get_bus_and_cs call. I don't think claim would have any effect here. and the set_speed here is to update if speed is diff b/w slave and the actual. If claim required here, this would also need during spi_get_bus_and_cs, but this isn't the case. > turns it back on when claiming.

Can you listed these cases, or some kind of non-working or no effect case would help here. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
