Resending due to screwup in To: address line Hi Felipe, Ben, This is a host-mode driver for the Synopsys DesignWare HS OTG controller. This is the same controller whose peripheral mode is implemented by the existing s3c-hsotg driver. The idea is to add a dwc2/ directory alongside the existing dwc3/ directory, initially to contain just this host-mode driver. Once that has been accepted we would then like to move the s3c-hsotg driver into this directory and integrate it to make a dual-role driver. Finally we would implement support for the OTG features of the controller. This driver is still a work in progress, to wit: - Only Control and Bulk transfer types have been tested so far, using the mass-storage gadget. - Only a PCI bus interface has been implemented so far. However all the PCI specific code is isolated to a single file, so it should be fairly easy to add a platform device interface. - The driver has a couple dozen module parameters to control various optional features of the controller. I realize module parameters are frowned upon these days, so I would appreciate any advice on the best way to implement these in an acceptable manner. - There is no power-management support yet. - There is some code present to implement DRD and OTG support, but it is incomplete due to the missing peripheral-mode code. - There is quite a bit of debug code included. I would like to keep that until the integration with s3c-hsotg is complete, then most of it can be stripped out. The patches are checkpatch clean, except for boatloads of camel-case warnings due to the reuse of s3c-hsotg.h for the register definitions. Comments?
