This corresponds to SPI mode 0, with CPOL=0 and CPHA=0. The spi-cpol property without spi-cpha instead selects SPI mode 2, which uses the opposite clock edges and does not match the ADS7846 serial interface. Remove the invalid property. This also matches the driver behavior: ads7846_probe() clears SPI_MODE_X_MASK and selects SPI_MODE_0 before calling spi_setup(). This fixes the following dtbs_check warning: imx27-eukrea-mbimxsd27-baseboard.dtb: ads7846@0 (ti,ads7846): Unevaluated properties are not allowed (spi-cpol was unexpected) Signed-off-by: Fabio Estevam --- Changes since v1: - Remove spi-cpol from the dts instead of adding it to the binding.
