Stefan Wahren 4f8c8edede spi: spi-fsl-lpspi: Fix scldiv calculation ... [ Upstream commit 730bbfaf7d4890bd99e637db7767dc68cfeb24e7 ] The effective SPI clock frequency should never exceed speed_hz otherwise this might result in undefined behavior of the SPI device. Currently the scldiv calculation could violate this constraint. For the example parameters perclk_rate = 24 MHz and speed_hz = 7 MHz, the function fsl_lpspi_set_bitrate will determine perscale = 0 and scldiv = 1, which is a effective SPI clock of 8 MHz. So fix this by rounding up the quotient of perclk_rate and speed_hz. While this never change within the loop, we can pull this out.
