usb: dwc3: make dwc3_get_device_id() return the id

2012-04-02T17:31:33Z

commit 075cd14d2a8d35afc39ad28fc7b968275881266b upstream. We always return zero instead of the id we found. Signed-off-by: Dan Carpenter Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: dwc3: core: fix cached revision on our structure

2011-12-14T19:59:30Z

All our revision macros are defined with the entire 32-bits which we read from GSNPSID register, so we must cache all 32-bits properly rather than masking the top 16-bits. This will fix all revision checks we have on current driver. Signed-off-by: Felipe Balbi

usb: dwc3: use correct hwparam register for power mgm check

2011-12-12T09:48:44Z

We mask the correct bits within the wrong register. The power optimization mode is stored hwparam1 register and not in hwparam0. Reported-by: Partha Basak Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: dwc3: move generic dwc3 code from gadget into core

2011-12-12T09:48:27Z

A few inits like the scale value or the removal of the DISSCRAMBLE is done in the gadget code however it touches a general register. Move this piece to the core.c file since it is likely to be requied by both, parts of the core (device and host). Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: dwc3: use a helper function for operation mode setting

2011-12-12T09:48:26Z

There are two where need to set operational mode: - during initialization while we decide to run in host,device or DRD mode - at runtime via the debugfs interface. This patch provides a new function which sets the operational mode and moves its initialiation to the mode switch instead in the gadget code itself.

usb: dwc3: core: drop DWC3_EVENT_BUFFERS_MAX

2011-12-12T09:48:24Z

hardware will tell us how many event buffers we need to support, so let's allocate the array dynamically too. Signed-off-by: Felipe Balbi

usb: dwc3: move dwc3 device ID bitmap to core.c

2011-12-12T09:48:21Z

if we want to support situations where we have both SoC and PCIe versions of the IP on the same platform, we need to have sequential numbers between them, otherwise we will still have name collisions. Because of that, we need to move dwc3_get/put_device_id() to core.c and export that symbol to be used by glue layers. Signed-off-by: Felipe Balbi

usb: dwc3: add a platform device alias

2011-12-12T09:48:17Z

We can have three modules here: dwc3.ko, dwc3-omap.ko and dwc3-pci.ko. The later have already ids-aliases for probing and is fine. The omap module has alias for DT but lacks alias for the "native" platform_device. Maybe we should get rid of it and stick to the DT name? Both glue modules create a new device for which the dwc3.ko module is responsible and that one lacks the platform alias. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: dwc3: add xHCI Host support

2011-12-12T09:48:12Z

The Designware USB3 IP can be configured with an internal xHCI. If we're running on such a version, let's start the xHCI stack. Signed-off-by: Felipe Balbi
