spi/imx: set the inactive state of the clock according to the clock polarity
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 <knut.wohlrab@de.bosch.com> Signed-off-by: Dirk Behme <dirk.behme@de.bosch.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
