From: Knut Wohlrab <redacted> There are SPI devices which need a SPI clock with active low polarity and high inactive state. Add the setting of the inactive state ECSPIx_CONFIGREG:SCLK CTL according to the clock polarity ECSPIx_CONFIGREG:SCLK POL: DT without "spi-cpol" = 0 = clock active high polarity = inactive state low DT with "spi-cpol" = 1 = clock active low polarity = inactive state high Signed-off-by: Knut Wohlrab <redacted>
