2015-10-04misc: mic: Remove COSM functionality from the MIC card driverAshutosh Dixit1-1/+2
Since card side COSM functionality, to trigger MIC device shutdowns and communicate shutdown status to the host, is now moved into a separate COSM client driver, this patch removes this functionality from the base MIC card driver. The mic_bus driver is also updated to use the device index provided by COSM rather than maintain its own device index.

2014-07-11misc: mic: add a bus driver for virtual MIC devicesSudeep Dutt1-0/+110
This MIC virtual bus driver takes the responsibility of creating all the virtual devices connected to the PCIe device on the host and the platform device on the card. The MIC bus hardware operations provide a way to abstract certain hardware details from the base physical devices. Examples of devices added on the MIC virtual bus include host DMA and card DMA. This abstraction enables using a common DMA driver on host and card.
