Could you confirm this? cat /sys/class/spi_transport/target0:0:0/period cat /sys/class/spi_transport/target0:0:0/max_period Now, if the max_period is 25, try doing echo 12.5 > /sys/class/spi_transport/target0:0:0/max_period and then echo 1 > /sys/class/spi_transport/target0:0:0/revalidate to trigger a revalidation of the domain and see if it comes up to 160.
