It works like the PCI -driver and is based on it. This is for devices which do not have an own -bus but their OHCI controller works like a PCI controller. It will be -used for the Broadcom bcma and ssb USB OHCI controller. - -Acked-by: Alan Stern <stern@rowland.harvard.edu> -Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> ---- - drivers/usb/host/Kconfig         |   10 ++ - drivers/usb/host/ohci-hcd.c      |    5 + - drivers/usb/host/ohci-platform.c |  194 ++++++++++++++++++++++++++++++++++++++ - include/linux/usb/ohci_pdriver.h |   38 ++++++++ - 4 files changed, 247 insertions(+), 0 deletions(-) - create mode 100644 drivers/usb/host/ohci-platform.c - create mode 100644 include/linux/usb/ohci_pdriver.h - ---- a/drivers/usb/host/Kconfig -+++ b/drivers/usb/host/Kconfig -@@ -393,6 +393,16 @@ config USB_CNS3XXX_OHCI - 	  Enable support for the CNS3XXX SOC's on-chip OHCI controller. - 	  It is needed for low-speed USB 1.0 device support. -  -+config USB_OHCI_HCD_PLATFORM -+	bool "Generic OHCI driver for a platform device" -+	depends on USB_OHCI_HCD && EXPERIMENTAL -+	default n -+	---help--- -+	  Adds an OHCI host driver for a generic platform device, which -+	  provieds a memory space and an irq. -+ -+	  If unsure, say N. -+ - config USB_OHCI_BIG_ENDIAN_DESC - 	bool - 	depends on USB_OHCI_HCD ---- a/drivers/usb/host/ohci-hcd.c -+++ b/drivers/usb/host/ohci-hcd.c -@@ -1121,6 +1121,11 @@ MODULE_LICENSE ("GPL"); - #define PLATFORM_DRIVER		ohci_xls_driver - #endif -  -+#ifdef CONFIG_USB_OHCI_HCD_PLATFORM -+#include "ohci-platform.c" -+#define PLATFORM_DRIVER		ohci_platform_driver -+#endif -+ - #if	!defined(PCI_DRIVER) &&		\ - 	!defined(PLATFORM_DRIVER) &&	\ - 	!defined(OMAP1_PLATFORM_DRIVER) &&	\ ---- /dev/null -+++ b/drivers/usb/host/ohci-platform.c -@@ -0,0 +1,194 @@ -+/* -+ * Generic platform ohci driver -+ * -+ * Copyright 2007 Michael Buesch <m@bues.ch> -+ * Copyright 2011-2012 Hauke Mehrtens <hauke@hauke-m.de> -+ * -+ * Derived from the OCHI-SSB driver -+ * Derived from the OHCI-PCI driver -+ * Copyright 1999 Roman Weissgaerber -+ * Copyright 2000-2002 David Brownell -+ * Copyright 1999 Linus Torvalds -+ * Copyright 1999 Gregory P.
