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.
