From 97b3ffa233b94741ae77d6ece2476331935bf15b Mon Sep 17 00:00:00 2001 From: Raviteja Garimella Date: Tue, 28 Mar 2017 16:32:03 +0530 Subject: usb: gadget: udc: amd5536: split core and PCI layer This patch splits the amd5536udc driver into two -- one that does pci device registration and the other file that does the rest of the driver tasks like the gadget/ep ops etc for Synopsys UDC. This way of splitting helps in exporting core driver symbols which can be used by any other platform/pci driver that is written for the same Synopsys USB device controller. The current patch also includes a change in the Kconfig and Makefile. A new config option USB_SNP_CORE will be selected automatically when any one of the platform or pci driver for the same UDC is selected. Main changes: - amd5536udc_pci.c: PCI device registration is moved to this file. - amd5536udc.c: This file does rest of the core UDC fucntionality. 9 symbols are exported so as to be used by amd5536udc_pci.c. Module parameter definitions are moved to header file. - amd5536udc.h: Function declarations, module parameters definitions and few common header file includes are added to this file - Kconfig: New USB_SNP_CORE option is added which will be auto selected when any pci or platform driver config option for the UDC is chosen. - Makefile: Compiles the core and pci files separately.
