SPIM0, SPIM1, SPIM2 allow bogus bps settings #542
Description
Using SPI via SPIM0, SPIM1 or SPIM2 on nRF52833 and others is limited to 8Mbps, but right now setting 16Mbps or 32Mbps does not cause a compile-time or runtime error. Instead, the SPI port works extremely poorly and slowly.
Will probably need a breaking change to catch this at compile time or even at runtime.
