Stefan Wahren ad994eda5d spi: spi-fsl-lpspi: Clamp too high speed_hz ... [ Upstream commit af357a6a3b ] Currently the driver is not able to handle the case that a SPI device specifies a higher spi-max-frequency than half of per-clk: per-clk should be at least two times of transfer speed Fix this by clamping to the max possible value and use the minimum SCK period of 2 cycles.
