Converting ncm to the new function interface requires converting the USB ncm's function code and its users. This patch converts the f_ncm.c to the new function interface. The file is now compiled into a separate usb_f_ncm.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by:

Add an interface to create a struct netdev_dev filled with default values, an interface which makes it an interface to fill the struct with useful values and an interface to read the values set. The patch also adds an interface to register the net device associated with an ethernet-over-usb link. Signed-off-by:

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. Acked-by:

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. Signed-off-by:

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(). Reported-by:

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). Signed-off-by:

Registered Tegra USB PHY as a separate platform driver. To synchronize host controller and PHY initialization, used deferred probe mechanism. As PHY should be initialized before EHCI starts running, deferred probe of Tegra EHCI driver till PHY probe gets completed. Got rid of instance number based handling in host driver. Made use of DT params to get the PHY Pad registers. Signed-off-by:

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:

The driver supports both ab8500 and ab8505, but the actual phy tuning values logic sets ab8500 values: if (!is_ab8500_2p0_or_earlier(ab->ab8500)) which is supposed to set values for ab8500, but incorrectly results true for ab8505 too.
