spi: imx: fix ecspi mode setup Fixed problem with setting spi mode 0 or 1 after setting mode 2 or 3 SPI_MODE_0 and SPI_MODE_1 requires clock low when inactive. SPI_MODE_2 and SPI_MODE_3 requires clk high when inactive. Currently driver can just set bits in fields SCLK_PHA (SPI Clock/Data Phase Control), SCLK_POL (SPI Clock Polarity Control), SCLK_CTL (controls the inactive state of SCLK) ans SS_POL (SPI SS Polarity Select) of ECSPIx_CONFIGREG register. This patch allows driver to clear corresponding bits in these fields. Signed-off-by: Andrew Y. Kuksov <qxovxp@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
