* usb: gadget: rndis: convert into moduleAndrzej Pietrasiewicz2013-06-107-3/+32
| | | | | | | | | | | | | In order to convert to configfs the usb functions need to be converted to a new interface and compiled as modules. This patch creates an rndis module which will be used by the new functions. After all users of f_rndis are converted to the new interface, this module can be merged with f_rndis module.

* usb: gadget: u_ether: convert into moduleAndrzej Pietrasiewicz2013-06-1010-52/+98
| | | | | | | | | | | | | | | u_ether.c has been #include'd by all gadgets which implement USB Ethernet functions. In order to add configfs support, the f_ecm.c, f_eem.c, f_ncm.c, f_subset.c, f_rndis.c need to be converted into modules and must not be #include'd. Consequently, the u_ether.c needs to be a module too, in a manner similar to u_serial.c. The resulting module should not take any parameters, so they are pushed to the current users of it, that is ether.c, g_ffs.c, multi.c, ncm.c, nokia.c.

| | | | | | | | | | | prm_to_uac2() is broken because it tests against pointer it itself mapped onto, which will never be different. Fix the mapping by adding pointer to parent chip in each rtd param and removing the prm_to_uac2().

* usb: gadget: r8a66597-udc: do not unlock unheld spinlock in ↵Alexey Khoroshilov2013-06-101-2/+2
| | | | | | | | | | | | | | | r8a66597_sudmac_irq() r8a66597_irq() processes sudmac part (r8a66597_sudmac_irq()) before locking r8a66597->lock. But transfer_complete(), that is called inside (r8a66597_sudmac_irq()->sudmac_finish()->transfer_complete()), expects r8a66597->lock is locked. As a result unheld spinlock can be unlocked. The patch just moves locking before calling r8a66597_sudmac_irq(). Found by Linux Driver Verification project (linuxtesting.org).

* usb: phy: registering Tegra USB PHY as platform driverVenu Byravarasu2013-05-303-210/+230
| | | | | | | | | | | | | | | Registered Tegra USB PHY as a separate platform driver. To synchronize host controller and PHY initialization, used deferred probe mechanism.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM: tegra: DT-related fixes needed by the USB tree The Tegra USB bindings were in bad shape. The patches in this branch fix the binding definitions, and make all the necessary additions to the DT files. Stale nodes/properties will be removed early in 3.12 once the USB driver has been updated for the new binding. These changes are needed in both the USB tree, to allow the driver to be updated to handle them, and the Tegra tree, so that various tree- wide DT changes (e.g. conversion of IRQ/GPIO/clock constants to defines) can be applied on top of them. * tag 'tegra-for-3.11-deps-for-usb': ARM: tegra: update device trees for USB binding rework ARM: tegra: modify ULPI reset GPIO properties ARM: tegra: finalize USB EHCI and PHY bindings Signed-of-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing Tegra USB bindings have a few issues: 1) Many properties are documented as being part of the EHCI controller node, yet they apply more to the PHY device. They should be moved. 2) Some registers in PHY1 are shared with PHY3, and hence PHY3 needs a reg entry to point at PHY1's register space. We can't assume the PHY1 driver is present, so the PHY3 driver will directly access those registers. 3) The list of clocks required by the PHY was missing some required entries. 4) UTMI PHY Timing parameters are added 5) VBUS control is now specified using a regulator rather than a plain GPIO 6) Added nvidia,is-wired property to indicate whether the device is hard wired on the board, or pluggable. This patch fixes the binding definition to resolve these issues. Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>

* | usb: musb: factor out hcd initalizationDaniel Mack2013-05-284-39/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The musb struct is currently allocated along with the hcd, which makes it difficult to build a driver that only acts as gadget device. Fix this by allocating musb directly, and keep the hcd around as a pointer in the musb struct. struct hc_driver musb_hc_driver can now also be static to musb_host.c, and the macro musb_to_hcd() is just a pointer dereferencer for now, and will be eliminated later.

| | | | | | | | | | | | | | | | | | This function has its only user in musb_virthub.c, so let's move it there and make it static. Signed-off-by: Daniel Mack <zonque@gmail.com> Acked-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | This will be done from a more appropriate location and as it doesn't work anyway, it can safely be removed before the other changes.

| | | | | | | | | | | | | | | | | | In particular, this introduces musb_host_resume_root_hub()and musb_host_poke_root_hub() which will be stubbed out later. Signed-off-by: Daniel Mack <zonque@gmail.com> Acked-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | Let the function declarations live in the header files they belong to, which makes it easier to stub them out later. Signed-off-by: Daniel Mack <zonque@gmail.com> Acked-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Felipe Balbi <balbi@ti.com>
