usb: gadget: Gadget directory cleanup - group legacy gadgets

2014-07-16T17:14:05+00:00

The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the legacy gadgets (i.e. those not using configfs) into a separate directory. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi

usb: gadget: Convert drivers to use module_usb_composite_driver()

2014-07-10T13:37:09+00:00

Use the module_usb_composite_driver() macro where applicable to eliminate the module_init/module_exit boilerplate in USB gadget composite drivers. Signed-off-by: Tobias Klauser Signed-off-by: Felipe Balbi

usb: gadget: consider link speed for bMaxPower

2013-01-10T10:38:52+00:00

The USB 2.0 specification says that bMaxPower is the maximum power consumption expressed in 2 mA units and the USB 3.0 specification says that it is expressed in 8 mA units. This patch renames bMaxPower to MaxPower and the various /2 and *2 are removed. Before reporting the config descriptor, the proper value is computer based on the speed, all in-tree users are updated. MaxPower is also increased to u16 so we can store the nokia gadget value which is larger than the max value allowed for u8. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: remove usb_gadget_controller_number()

2012-09-10T13:43:24+00:00

The bcdDevice field is defined as |Device release number in binary-coded decimal in the USB 2.0 specification. We use this field to distinguish the UDCs from each other. In theory this could be used on the host side to apply certain quirks if the "special" UDC in combination with this gadget is used. This hasn't been done as far as I am aware. In practice it would be better to fix the UDC driver before shipping since a later release might not need this quirk anymore. There are some driver in tree (on the host side) which use the bcdDevice field to figure out special workarounds for a given firmware revision. This seems to make sense. Therefore this patch converts all gadgets (except a few) to use the kernel version instead a random 2 or 3 plus the UDC number. The few that don't report kernel's version are: - webcam This one reports always a version 0x10 so allow it to do so in future. - nokia This one reports always 0x211. The comment says that this gadget works only if the UDC supports altsettings so I added a check for this. - serial This one reports 0x2400 + UDC number. Since the gadget version is 2.4 this could make sense. Therefore bcdDevice is 0x2400 here. I also remove various gadget_is_ macros which are unused. The remaining few macros should be moved to feature / bug bitfield. Acked-by: Michal Nazarewicz Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: Provide a default implementation of default manufacturer string

2012-09-10T13:13:02+00:00

Some gadgets provide custom entry here. Some may override it with an etntry that is also created by composite if there was no value sumbitted at all. This patch removes all "custom manufacturer" strings which are the same as these which are created by composite. Then it moves the creation of the default manufacturer string to usb_composite_overwrite_options() in case no command line argument has been used and the entry is still an empty string. By doing this we get rid of the global variable "composite_manufacturer" in composite. Acked-by: Michal Nazarewicz Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: make sure each gadget is using same index for Product, Serial,…

2012-09-10T13:13:00+00:00

The index in usb_string array is defined by the gadget. The gadget can choose which index entry it assigns for the serial number and which the product name. The gadget has just to ensure that the descriptor contains the proper string id which is assigned by composite. If the composite layer knows the index of the "default" information which will be overwritten by module parameters, it can be used later to overwrite it.

usb: gadget: push VID/PID/USB BCD module option into gadgets

2012-09-10T13:12:59+00:00

This patch moves the module options idVendor, idProduct and bcdDevice from composite.c into each gadgets. This ensures compatibility with current gadgets and removes the global variable which brings me step closer towards composite.c in libcomposite Acked-by: Michal Nazarewicz Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: use usb_string_ids_tab instead multiple usb_string_id()

2012-09-10T13:06:48+00:00

Using usb_string_ids_tab() instead multiple calls of usb_string_id() seems to be handy. It also allows to add string without many checks. Acked-by: Michal Nazarewicz Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi
