Hi Federico, Here is the patch. In it, I added a #define DWC_HSOTG_PCI, which if true will compile the PCI code, otherwise the original S3C platform code will be compiled. Of course, the final solution should not have any #ifdef's. I renamed the core data structures and functions from s3c_* to dwc_hsotg_*. The idea is, that code would be split out to a common file, the S3C-specific code would remain in s3c-hsotg.c and keep the s3c_ prefix, and the PCI-specific code would be moved to a new file. If you look towards the end of the patch, you will see a big #if/#else block, where if DWC_HSOTG_PCI is true, dwc_hsotg_probe/dwc_hsotg_remove functions are instantiated, otherwise s3c_hsotg_probe/s3c_hsotg_remove functions. That is most of the code that would be split out into the PCI and S3C wrappers, in addition to the #include's at the beginning. Then most of the #ifdef DWC_HSOTG_PCI conditional code would be eliminated. There is some more #ifdef DWC_HSOTG_PCI conditional code in the middle of the patch, like the power supply, regulator, and phy stuff, as well as some code that uses ARM-specific functions to read/write from the FIFOs. That code still needs some thinking about how it can be moved from the core code to the wrappers. The patch is 7 or 8 months old, so I'm not sure exactly which kernel version it applies to. I don't think the s3c-hsotg driver has changed much recently, so that shouldn't cause too much of a problem. -- Paul diff --git a/drivers/usb/gadget/Kconfig b/drivers/usb/gadget/Kconfig index a53be32..1b3ad55 100644 --- a/drivers/usb/gadget/Kconfig +++ b/drivers/usb/gadget/Kconfig @@ -273,7 +273,7 @@ config USB_PXA27X config USB_S3C_HSOTG tristate "S3C HS/OtG USB Device controller" - depends on S3C_DEV_USB_HSOTG +# depends on S3C_DEV_USB_HSOTG help The Samsung S3C64XX USB2.0 high-speed gadget controller integrated into the S3C64XX series SoC. diff --git a/drivers/usb/gadget/s3c-hsotg.c b/drivers/usb/gadget/s3c-hsotg.c index 6f696ee..2f827f5 100644 --- a/drivers/usb/gadget/s3c-hsotg.c +++ b/drivers/usb/gadget/s3c-hsotg.c @@ -16,11 +16,19 @@ * published by the Free Software Foundation. */ +#define DWC_HSOTG_PCI 1 + #include <linux/kernel.h> #include <linux/module.h> #include <linux/spinlock.h> #include <linux/interrupt.h> + +#ifdef DWC_HSOTG_PCI +#include <linux/pci.h> +#else #include <linux/platform_device.h> +#endif + #include <linux/dma-mapping.h> #include <linux/debugfs.h> #include <linux/seq_file.h> @@ -32,18 +40,30 @@ #include <linux/usb/ch9.h> #include <linux/usb/gadget.h> + +#ifdef DWC_HSOTG_PCI +#include <asm/io.h> +#else #include <linux/platform_data/s3c-hsotg.h> #include <mach/map.h> +#endif #include "s3c-hsotg.h" +#ifdef DWC_HSOTG_PCI +#define PCI_VENDOR_ID_SYNOPSYS 0x16c3 +#define PCI_DEVICE_ID_SYNOPSYS_HAPSUSB3 0xabc0 +#endif + #define DMA_ADDR_INVALID (~((dma_addr_t)0)) +#ifndef DWC_HSOTG_PCI static const char * const s3c_hsotg_supply_names[] = { "vusb_d", /* digital USB supply, 1.2V */ "vusb_a", /* analog USB supply, 1.1V */ };
