If we shutdown without stopping the gadget first or removing the cable, gadget manages to configure itself again: root@pandora /root# poweroff The system is going down NOW! Requesting system poweroff [ 47.714385] musb-hm halted. [ 48.120697] gadget: suspend [ 48.123748] gadget: reset config [ 48.127227] gadget: ecm deactivated [ 48.130981] usb0: gether_disconnect [ 48.281799] gadget: high-speed config #1: CDC Ethernet (ECM) [ 48.287872] gadget: init ecm [ 48.290985] gadget: notify connect false [ 48.295288] gadget: notify speed 425984000 This is not only unwanted, it's also happening on half-unitialized state, after musb_shutdown() has returned, which sometimes causes hardware to fail to work after reboot. Let's better properly stop gadget on shutdown too. This patch moves musb_gadget_cleanup out of musb_free(), which has 2 callsites: probe error path and musb_remove. On probe error path it was superflous since musb_gadget_cleanup is called explicitly there, and musb_remove() calls musb_shutdown(), so cleanup will get called as before.

Commit 0020afb369859472a461ef4af6410732e929d402 (ARM: mach-davinci: remove mach/memory.h) removed mach/memory.h for DaVinci which broke DaVinci MUSB build. mach/memory.h is not actually needed in davinci.c, so remove it. While at it, also remove some more machine specific inclulde files which are not needed for build. Tested on DM644x EVM using USB card reader.

2011-12-20usb: musb: fix pm_runtime mismatchFelipe Contreras
In musb_init_controller() there's a pm_runtime_put(), but there's no pm_runtime_get(), which creates a mismatch that causes the driver to sleep when it shouldn't. This was introduced in 7acc619[1], but it wasn't triggered in my setup until 18a2689[2] was merged to Linus' branch at point df0914[3]. IOW; when PM is working as it was supposed to. However, it seems most of the time this is used in a way that keeps the counter above 0, so nobody noticed. Also, it seems to depend on the configuration used in versions before 3.1, but not later (or in it). I found the problem by loading isp1704_charger before any usb gadgets: http://article.gmane.org/gmane.linux.kernel/1226122 All versions after 2.6.39 are affected.

2011-12-12usb: musb: use a Kconfig choice to pick the right DMA methodArnd Bergmann
The logic to allow only one DMA driver in MUSB is currently flawed, because it also allows picking no DMA driver at all and also not selecting PIO mode. Using a choice statement makes this foolproof for now and also simplifies the Makefile. Unfortunately, we will have to revisit this when we start supporting multiple ARM platforms in a single kernel binary, because at that point we will actually need to select multiple DMA drivers and pick the right one at run-time.

This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

2011-11-29usb: musb: PM: fix context save/restore in suspend/resume pathKevin Hilman
Currently the driver tries to save context in the suspend path, but will cause an abort if the device is already runtime suspended. This happens, for example, if MUSB loaded/compiled-in, in host mode, but no USB devices are attached. MUSB will be runtime suspended, but then attempting a system suspend will crash due to the context save being attempted while the device is disabled. On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be called late in the suspend path (by the PM domain layer) if the driver is not already runtime suspended, ensuring a full shutdown. Therefore, the context save is not needed in the ->suspend() method since it will be called in the ->runtime_suspend() method anyways (similarily for resume.) NOTE: this leaves the suspend/resume methods basically empty (with some FIXMEs and comments, but I'll leave it to the maintainers to decide whether to remove them.

2011-11-14USB: Remove the SAW_IRQ hcd flagAlan Stern
The HCD_FLAG_SAW_IRQ flag was introduced in order to catch IRQ routing errors: If an URB was unlinked and the host controller hadn't gotten any IRQs, it seemed likely that the IRQs were directed to the wrong vector. This warning hasn't come up in many years, as far as I know; interrupt routing now seems to be well under control. Therefore there's no reason to keep the flag around any more. This patch (as1495) finally removes it. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-11-14usb: musb: fix compilation breakage introduced by de47725Felipe Balbi
commit de47725 (include: replace linux/module.h with "struct module" wherever possible) introduced a compilation breaked when it removed <linux/module.h> from <linux/device.h> which musb glue layers were (mistakenly) relying on. Include that header to fix the compile error. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
