It will be -used for the Broadcom bcma and ssb USB OHCI controller. - -Signed-off-by: Hauke Mehrtens ---- - drivers/usb/host/Kconfig | 10 ++ - drivers/usb/host/ohci-hcd.c | 21 ++++- - drivers/usb/host/ohci-platform.c | 197 ++++++++++++++++++++++++++++++++++++++ - 3 files changed, 227 insertions(+), 1 deletions(-) - create mode 100644 drivers/usb/host/ohci-platform.c - ---- a/drivers/usb/host/Kconfig -+++ b/drivers/usb/host/Kconfig -@@ -378,6 +378,16 @@ 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 "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 -@@ -1111,6 +1111,11 @@ MODULE_LICENSE ("GPL"); - #define PLATFORM_DRIVER ohci_hcd_ath79_driver - #endif - -+#ifdef CONFIG_USB_OHCI_HCD_PLATFORM -+#include "ohci-platform.c" -+#define PLATFORM_OHCI_DRIVER ohci_platform_driver -+#endif -+ - #if !defined(PCI_DRIVER) && \ - !defined(PLATFORM_DRIVER) && \ - !defined(OMAP1_PLATFORM_DRIVER) && \ -@@ -1120,7 +1125,8 @@ MODULE_LICENSE ("GPL"); - !defined(PS3_SYSTEM_BUS_DRIVER) && \ - !defined(SM501_OHCI_DRIVER) && \ - !defined(TMIO_OHCI_DRIVER) && \ -- !defined(SSB_OHCI_DRIVER) -+ !defined(SSB_OHCI_DRIVER) && \ -+ !defined(PLATFORM_OHCI_DRIVER) - #error "missing bus glue for ohci-hcd" - #endif - -@@ -1204,9 +1210,19 @@ static int __init ohci_hcd_mod_init(void - goto error_tmio; - #endif - -+#ifdef PLATFORM_OHCI_DRIVER -+ retval = platform_driver_register(&PLATFORM_OHCI_DRIVER); -+ if (retval) -+ goto error_platform; -+#endif -+ - return retval; - - /* Error path */ -+#ifdef PLATFORM_OHCI_DRIVER -+ platform_driver_unregister(&PLATFORM_OHCI_DRIVER); -+ error_platform: -+#endif - #ifdef TMIO_OHCI_DRIVER - platform_driver_unregister(&TMIO_OHCI_DRIVER); - error_tmio: -@@ -1260,6 +1276,9 @@ module_init(ohci_hcd_mod_init); - - static void __exit ohci_hcd_mod_exit(void) - { -+#ifdef PLATFORM_OHCI_DRIVER -+ platform_driver_unregister(&PLATFORM_OHCI_DRIVER); -+#endif - #ifdef TMIO_OHCI_DRIVER - platform_driver_unregister(&TMIO_OHCI_DRIVER); - #endif ---- /dev/null -+++ b/drivers/usb/host/ohci-platform.c -@@ -0,0 +1,197 @@ -+/* -+ * Generic platform ohci driver -+ * -+ * Copyright 2007 Michael Buesch -+ * Copyright 2011 Hauke Mehrtens -+ * -+ * Derived from the OHCI-PCI driver -+ * Copyright 1999 Roman Weissgaerber -+ * Copyright 2000-2002 David Brownell -+ * Copyright 1999 Linus Torvalds -+ * Copyright 1999 Gregory P.
