2019-02-27usb: chipidea: imx: set power polarityPhilipp Puschmann
This patch adds support to set the power line polarity for i.MX SoCs. To let the USB controller control the power it may be necessary to configure the polarity of the power line. So far the polarity was configured by Bootloader or alternatively the power line was muxed as gpio and driven by a regulator. Also make use of of_property_read_bool.

2019-02-22usb: core: add option of only authorizing internal devicesDmitry Torokhov
On Chrome OS we want to use USBguard to potentially limit access to USB devices based on policy. We however to do not want to wait for userspace to come up before initializing fixed USB devices to not regress our boot times. This patch adds option to instruct the kernel to only authorize devices connected to the internal ports. Previously we could either authorize all or none (or, by default, we'd only authorize wired devices). The behavior is controlled via usbcore.authorized_default command line option.

For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); Notice that, in this case, variable len is not necessary, hence it is removed.

This change means the naming of the mux device connections can be updated. Alternate and Accessory Modes will both be handled with muxes named "mode-switch", and the orientation switches will be named "orientation-switch".

Since we're disabling the endpoint anyway, we don't worry about getting endpoint command completion interrupt. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2019-02-12usb: musb: Kconfig: Drop dependency on CONFIG_USB for jz4740Paul Cercueil
The Kconfig entry previously depended on USB_OTG_BLACKLIST_HUB unconditionally, which is an option that is only available when CONFIG_USB is enabled. However, the USB IP in the JZ4740 SoC does not support host mode, only gadget mode, so it makes sense to allow it to build when CONFIG_USB is not set.

2019-02-12usb: musb: Kconfig: Drop dependency on MACH_JZ4740 for jz4740Paul Cercueil
Depending on MACH_JZ4740 prevent us from creating a generic kernel that works on more than one MIPS board. Instead, we just depend on MIPS being set.
