[PATCH] spidev: Enable the Liebherr's BK4 board to work with spidev driver

From: Lukasz Majewski
Date: Thu Sep 27 2018 - 18:32:14 EST


With this commit the DSPI driver on the BK4 board can be used for SPI
transmission managed from user space (via /dev/spidev0.0).

Example usage/testing:
insmod ./spi-fsl-dspi.ko
./spidev_test -D /dev/spidev0.0 -s 3000000 -v -H -b 8 -p "\xCC\x11\x22\x74"
