#     mtd: spi-nor: aspeed: limit the maximum SPI frequency
#     
#     The optimize read algo can choose a 100MHz SPI frequency which might
#     be a bit too high for dual output IO on some chips, for the W25Q256 on
#     palmetto for instance. The MX66L1G45G on witherspoon should be fine
#     though. Also, the second chip of the FMC controller does not get any
#     optimize settings for reads. Only the first is configured by U-Boot.
#     
#     To fix these two issues, we introduce a "spi-max-frequency" property
#     in the device tree which will be used to cap the optimize read
#     algorithm and we run the algo on the FMC controller chips as well.
#     
#     By default, the frequency setting is 50MHz.
