The ssb bus just -exposes one device which serves the OHCI and the EHCI controller at the -same time. This driver probes for this USB controller and creates and -registers two new platform devices which will be probed by the new -generic platform device driver. This makes it possible to use the EHCI -and the OCHI controller on the ssb bus at the same time. - -The old ssb OHCI USB driver will be removed in the next step as this -driver also provide an OHCI driver and an EHCI for the cores supporting -it. - -Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> ---- - drivers/usb/host/Kconfig | 12 ++ - drivers/usb/host/Makefile | 1 + - drivers/usb/host/ssb-hcd.c | 273 ++++++++++++++++++++++++++++++++++++++++++++ - 3 files changed, 286 insertions(+), 0 deletions(-) - create mode 100644 drivers/usb/host/ssb-hcd.c --- a/drivers/usb/host/Kconfig +++ b/drivers/usb/host/Kconfig @@ -50,12 +26,12 @@ Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> +obj-$(CONFIG_USB_HCD_SSB) += ssb-hcd.o --- /dev/null +++ b/drivers/usb/host/ssb-hcd.c -@@ -0,0 +1,273 @@ +@@ -0,0 +1,279 @@ +/* + * Sonics Silicon Backplane + * Broadcom USB-core driver (SSB bus glue) + * -+ * Copyright 2011 Hauke Mehrtens <hauke@hauke-m.de> ++ * Copyright 2011-2012 Hauke Mehrtens <hauke@hauke-m.de> + * + * Based on ssb-ohci driver + * Copyright 2007 Michael Buesch <m@bues.ch> @@ -75,7 +51,8 @@ Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> +#include <linux/delay.h> +#include <linux/platform_device.h> +#include <linux/module.h> -+#include <linux/usb/hci_driver.h> ++#include <linux/usb/ehci_pdriver.h> ++#include <linux/usb/ohci_pdriver.h> + +MODULE_AUTHOR("Hauke Mehrtens"); +MODULE_DESCRIPTION("Common USB driver for SSB Bus"); @@ -146,13 +123,14 @@ Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> + return flags; +} + -+static const struct usb_hci_pdata p_data = { -+ .flags = USB_HCI_PDATA_PORT_POWER_SET, -+ .power_set_is_on = 1, ++static const struct usb_ehci_pdata ehci_pdata = { ++}; ++ ++static const struct usb_ohci_pdata ohci_pdata = { +}; + +static struct platform_device * __devinit -+ssb_hcd_create_pdev(struct ssb_device *dev, char *name, u32 addr, u32 len) ++ssb_hcd_create_pdev(struct ssb_device *dev, bool ohci, u32 addr, u32 len) +{ + struct platform_device *hci_dev; + struct resource hci_res[2]; @@ -167,7 +145,8 @@ Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> + hci_res[1].start = dev->irq; + hci_res[1].flags = IORESOURCE_IRQ; + -+ hci_dev = platform_device_alloc(name, 0); ++ hci_dev = platform_device_alloc(ohci ?
