bus/fsl-mc: add support for 'driver_override' in the mc-bus
This patch is required for vfio-fsl-mc meta driver to successfully bind layerscape container devices for device passthrough. This patch adds a mechanism to allow a layerscape device to specify a driver rather than a layerscape driver provide a device match. Example to allow a device (dprc.1) to specifically bind with driver (vfio-fsl-mc):- - echo vfio-fsl-mc > /sys/bus/fsl-mc/devices/dprc.1/driver_override - echo dprc.1 > /sys/bus/fsl-mc/drivers/fsl_mc_dprc/unbind - echo dprc.1 > /sys/bus/fsl-mc/drivers/vfio-fsl-mc/bind Reviewed-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Acked-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Signed-off-by: Bharat Bhushan <Bharat.Bhushan@nxp.com> Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Signed-off-by: Diana Craciun <diana.craciun@oss.nxp.com> Link: https://lore.kernel.org/r/20200929085441.17448-4-diana.craciun@oss.nxp.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
