Ioana Ciornei 991e873223 soc: fsl: dpio: use a cpumask to identify which cpus are unused ... The current implementation of the dpio driver uses a static next_cpu variable to keep track of the index of the next cpu available. This approach does not handle well unbinding and binding dpio devices in a random order. For example, unbinding a dpio and then binding it again with the driver, will generate the below error: $ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/unbind $ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/bind [ 103.946380] fsl_mc_dpio dpio.5: probe failed. Number of DPIOs exceeds NR_CPUS. [ 103.955157] fsl_mc_dpio dpio.5: fsl_mc_driver_probe failed: -34 -bash: echo: write error: No such device Fix this error by keeping a global cpumask of unused cpus that will be updated at every dpaa2_dpio_[probe,remove].
