Hi, The commit df59fa7f4bca "spi: orion: support armada extended baud rates" was too optimistic for the maximum baud rate that the Armada SoCs can support. Fixing it is the purpose of the 1st patch. Actually the Armada SoCs do not have the same constraints, some of them have maximum absolute values whereas for the other it is linked to the TCLK value. The second patch takes care of managing all these cases. Then the third patch updates the dtsi in order to use the accurate value. Only the first patch fixes a bug observed on the board by using a too high frequency on the SPI bus. The other ones allow using the best maximum frequency available.
