bind() and pull is moved to udc core, call callbacks are verified by the upper layer. Signed-off-by:
-
Sebastian Andrzej Siewior authored
udc-core checks for valid callbacks so there is no need for the driver to do so. Also "can-be-bound-once" is verified by udc-core. The pull-up callback is called by udc-core afterwords.

udc_start() should only trigger the internal state machine and make minimal house keeping. Before that call udc-core calls the bind() callback and after the callback the pullup(). udc_stop() is simillar, udc-core calls pullup(), unbind() and finally udc_stop(). Signed-off-by:

The configuration is static however we only know the speed after we have connected with the other side. Signed-off-by:
-
Sebastian Andrzej Siewior authored
This value is now assigned during bind(). The configuration depends on static values assigned by dummy driver itself. So there is no need to defer this assigment until one know the actuall speed since the configuration is static and known early. Signed-off-by:

This is only required to be done once. There is no counter part to this in ->stop() so there is no need to re-do it next time. While here also init the max_stream size to 0 on SS speed. Signed-off-by:

maxpacket is set by the udc driver for ep0 very early. This value is copied by the function gadget used later for the USB_DT_DEVICE and USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3 we need set a different value here. In SS speed it is 2^x with x=9 and in HS we set something <= 64. If the UDC starts in SS and continues in HS after the cable has been plugged it will report a too small value. There setting of this value is defered and taken automaticly from the ep0 pointer where the UDC driver can update it according to the speed it detected _after_ a cable has been plugged.

now that we have the udc class, we can allow multiple gadget controller drivers to be compiled as modules. This will allow for distro-like kernels for embedded devices. With this patch, I managed to build an x86 kernel with support for many of the controllers enabled: CONFIG_USB_FUSB300=m CONFIG_USB_R8A66597=m CONFIG_USB_M66592=m CONFIG_USB_AMD5536UDC=m CONFIG_USB_CI13XXX_PCI=m CONFIG_USB_NET2272=m CONFIG_USB_NET2280=m CONFIG_USB_GOKU=m CONFIG_USB_LANGWELL=m CONFIG_USB_EG20T=m Also an ARM kernel with support for many controllers: CONFIG_USB_FUSB300=m CONFIG_USB_OMAP=m CONFIG_USB_R8A66597=m CONFIG_USB_GADGET_MUSB_HDRC=m CONFIG_USB_M66592=m CONFIG_USB_NET2272=m CONFIG_USB_DUMMY_HCD=m The next step would be to get rid of the direct access to arch/ and mach/ directories on some gadget controllers so that we can build all of them without depending on their respective ARCH_* symbols.

When we start building glue layers as modules, we need to be careful with the fifo_mode changes otherwise that weird ifdeferry won't evaluate correctly. Add the missing _MODULE variants for all glue layers to prevent everybody from using fifo_mode 2. Signed-off-by:

the MUSB IP is always OTG, so there's no point in adding so many ifdefs on the code. Drop those and always compile the driver for OTG support. This also allows us to drop the useless "driver mode" choice. For doing that, we need to make musb depend on both Host and Peripheral side. Signed-off-by:

This function has no user in my tree. It looks like it belongs to net2280 but it somehow morphed into the dummy_hcd. So I remove it before it spreads into more drivers. After some digging I figured out that the only user was removed in |commit 9079e91b |Author: David Brownell <david-b@pacbell.net> |Date: Wed May 7 16:00:36 2008 -0700 | | USB: serial gadget: cleanup/reorg Signed-off-by:

Before commit 53832daea ("usb: gadget: dummy_hcd: use the shared_hcd infrastructure") the is_otg field was set in dummy_udc_probe(). It seems to me that this field is used in gadget's bind function. Therefore I'm moving it before the bind() callback is called. Cc: Tatyana Brokhman <tlinder@codeaurora.org Signed-off-by: -

The removed code does the same thing as dummy_pullup(). The only difference is that in dummy_udc_stop() the first dummy_pullup() did not call usb_hcd_poll_rh_status(). Signed-off-by:

the gadget controller number is only used during bind() to update descriptors and/or check that a particular controller can support a particular gadget driver. Because of that, we can remove the ifdef trickery as it's a rather small optimization anyway. While at that, also sort the entries alphabetically and add a comment stating we want to keep the list ordered alphabetically. Signed-off-by:

This also fixes the error path: If the second device fails to register we never remove the first one. This is compile-tested only. I don't see any difference between those two.

In case pci_register_driver() fails it error will be 0 in case platform_driver_register() was fine. Also without PCI pci_register_driver() evaluates to 1 which is well, special. If platform_driver_register() returns EINVAL or EBUSY we end up with 0. Acked-by:

This patch adds a new module parameter to dummy_hcd called is_high_speed. When set to false the connected device will be forced to operate in full-speed mode. By default, this parameter is set to 'true'. Acked-by:

This patch adds SS support to the dummy hcd module. It may be used to test SS device when no (SS) HW is available. USB 3.0 hub includes 2 hubs - one HS and one SS. This patch adds support for a SS root hub in the dummy_hcd module. A new module parameter was added: is_super_speed. When set to true, a SS root hub will also be registered and the connected device will be enumerated over the SS root hub. The default of this parameter is false. Signed-off-by:

SuperSpeed USB has defined a new descriptor, called the Binary Device Object Store (BOS) Descriptor. It has also changed a bit the definition of SET_FEATURE and GET_STATUS requests to add USB3-specific details. This patch implements both changes to the Composite Gadget Framework.

This patch defines necessary fields to support streaming for USB3.0. It implements a new function, called usb_ep_autoconfig_ss(), to be used instead of the existing usb_ep_autoconfig() when working in SuperSpeed mode and there is a need to search for an endpoint according to the number of required streams.

Change usb_ep_enable() prototype to use endpoint descriptor from usb_ep. This optimization spares the FDs from saving the endpoint chosen descriptor. This optimization is not full though. To fully exploit this change, one needs to update all the UDCs as well since in the current implementation each of them saves the endpoint descriptor in it's internal (and extended) endpoint structure.

peripheral drivers are using usb_add_gadget()/usb_del_gadget() to register/unregister to the udc-core. The udc-core will take the first available gadget driver and attach function driver which is calling usb_gadget_register_driver(). This is the same behaviour we have right now. Only dummy_hcd was tested, the others were compiled tested.

this class will be used to abstract away several of the duplicated operations scattered among the USB gadget controller drivers. Later, we can add an atomic notifier to tell interested drivers about what's happening with the controller. Notifications such as suspend, resume, enumerated, etc. will be useful, at a minimum, for implementing usb charger detection. As part of the converting process usb_gadget_probe_driver() is no longer part of each udc but pushed into the ->stap() callback. The same for his couterpart. The core is currently set explicit to 'n'. It will be changed to 'y' once all users are converted since it provides functions which clash with other drivers. Signed-off-by:
