Allocate usb otg descriptor and initialize it according to gadget's otg capabilities, if usb_otg_caps is not set, keep settings as current gadget drivers. With this 2 new interfaces, gadget can use usb_otg_descriptor for OTG 1.x, and usb_otg20_descriptor for OTG 2.0 or above, and otg features can be decided by the combination of usb hardware property and driver config.

The A31 SoC uses the same musb controller as found in earlier SoCs, but it is hooked up slightly different. Its SRAM is private and no longer controlled through the SRAM controller, and its reset is controlled via a separate reset controller. This commit adds support for this setup.

This is based on initial code to get the Allwinner sunxi musb controller supported by Chen-Yu Tsai and Roman Byshko. This adds support for the Allwinner sunxi musb controller in both host only and otg mode. Peripheral only mode is not supported, as no boards use that. This has been tested on a cubietruck (A20 SoC) and an UTOO P66 tablet (A13 SoC) with a variety of devices in host mode and with the g_serial gadget driver in peripheral mode, plugging otg / host cables in/out a lot of times in all possible imaginable plug orders.

Use bind_deactivated flag instead of calling usb_function_deactivate() in function bind(). Field 'can_activate' in struct f_obex is no longer needed as setting 'bind_deactivated' flag makes us sure, that the function will be binded only if deactivation can be performed successfully.

Robert Baldyga authored
This patch introduces 'bind_deactivated' flag in struct usb_function. Functions which don't want to be activated automatically after bind should set this flag, and when they start to be ready to work they should call usb_function_activate(). When USB function sets 'bind_deactivated' flag, initial deactivation counter is incremented automatically, so there is no need to call usb_function_deactivate() in function bind.

Using usb_gadget_disconnect to make gadget temporarily invisible to host doesn't provide desired result, because gadget is connected immediately after binding regardless to previous usb_gadget_disconnect() calls. For this reason we use usb_gadget_deactivate() instead of usb_gadget_disconnect() to make it working as expected.

These functions allows to deactivate gadget to make it not visible to host and make it active again when gadget driver is finally ready. They are needed to fix usb_function_activate() and usb_function_deactivate() functions which currently are not working as usb_gadget_connect() is called immediately after function bind regardless to previous calls of usb_gadget_disconnect() function.

When a SoC supports both PHY interfaces but doesn't define HSPHY in DT/pdata, we will get an unnecessary dev_warn() which can mislead users into thinking that they're missing something. Instead, let's just silently rely on a correct default. If the HW default is wrong, then HSPHY is required and USB won't work, this will be motivation enough for engineers to patch their way into a working setup.

Since 39b2bbe3 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Currently this parameter is made optional with the help of a cpp trick. To allow dropping this hack convert callers to explictly pass a value for flags.

Use this additional parameter and the _optional variant to simplify the driver and improve error handling. Also expand the comment to explain why it's not sensible to switch to devm_gpiod_get and why the gpiod_put is also necessary. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.
