This patch adds the basic support for the USB Device Controller on Qualcomm MSM family of SOCs. The controller supports upto 16 endpoints including the default endpoint (ep0). All the data transfers are driven by DMA. VBUS line is also connected to PMIC chip. The module controlling PMIC chip notifies about cable connect/disconnect events. Hence, PHY comparators are turned off in low power mode. This driver was originally developed by Google and is available at http://android.git.kernel.org/?p=kernel/experimental.git. + +#define USB_ID (MSM_USB_BASE + 0x0000) +#define USB_HWGENERAL (MSM_USB_BASE + 0x0004) +#define USB_HWHOST (MSM_USB_BASE + 0x0008) +#define USB_HWDEVICE (MSM_USB_BASE + 0x000C) +#define USB_HWTXBUF (MSM_USB_BASE + 0x0010) +#define USB_HWRXBUF (MSM_USB_BASE + 0x0014) + +#ifdef CONFIG_ARCH_MSM7X00A +#define USB_SBUSCFG (MSM_USB_BASE + 0x0090) +#else +#define USB_AHBBURST (MSM_USB_BASE + 0x0090) +#define USB_AHBMODE (MSM_USB_BASE + 0x0098) +#endif + +#define USB_CAPLENGTH (MSM_USB_BASE + 0x0100) /* 8 bit */ +#define USB_HCIVERSION (MSM_USB_BASE + 0x0102) /* 16 bit */ +#define USB_HCSPARAMS (MSM_USB_BASE + 0x0104) +#define USB_HCCPARAMS (MSM_USB_BASE + 0x0108) +#define USB_DCIVERSION (MSM_USB_BASE + 0x0120) /* 16 bit */ +#define USB_USBCMD (MSM_USB_BASE + 0x0140) +#define USB_USBSTS (MSM_USB_BASE + 0x0144) +#define USB_USBINTR (MSM_USB_BASE + 0x0148) +#define USB_FRINDEX (MSM_USB_BASE + 0x014C) +#define USB_DEVICEADDR (MSM_USB_BASE + 0x0154) +#define USB_ENDPOINTLISTADDR (MSM_USB_BASE + 0x0158) +#define USB_BURSTSIZE (MSM_USB_BASE + 0x0160) +#define USB_TXFILLTUNING (MSM_USB_BASE + 0x0164) +#define USB_ULPI_VIEWPORT (MSM_USB_BASE + 0x0170) +#define USB_ENDPTNAK (MSM_USB_BASE + 0x0178) +#define USB_ENDPTNAKEN (MSM_USB_BASE + 0x017C) +#define USB_PORTSC (MSM_USB_BASE + 0x0184) +#define USB_OTGSC (MSM_USB_BASE + 0x01A4) +#define USB_USBMODE (MSM_USB_BASE + 0x01A8) +#define USB_ENDPTSETUPSTAT (MSM_USB_BASE + 0x01AC) +#define USB_ENDPTPRIME (MSM_USB_BASE + 0x01B0) +#define USB_ENDPTFLUSH (MSM_USB_BASE + 0x01B4) +#define USB_ENDPTSTAT (MSM_USB_BASE + 0x01B8) +#define USB_ENDPTCOMPLETE (MSM_USB_BASE + 0x01BC) +#define USB_ENDPTCTRL(n) (MSM_USB_BASE + 0x01C0 + (4 * (n))) + + +#define USBCMD_RESET 2 +#define USBCMD_ATTACH 1 +#define USBCMD_ATDTW (1 << 14) + +#define USBMODE_DEVICE 2 +#define USBMODE_HOST 3 +
This look like the arc/chipidea/mips ehci otg core. Why can't you reuse the ci13xxx_udc.c driver ? Or if ci13xxx_udc.c is too bad, rewrite a new generic version for this core.
