Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'In order to convert all of them to 1 tab + 'help', I ran the
following commend:$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

This patch introduce new Cadence USBSS DRD driver to Linux kernel.
The Cadence USBSS DRD Controller is a highly configurable IP Core which
can be instantiated as Dual-Role Device (DRD), Peripheral Only and
Host Only (XHCI)configurations.The current driver has been validated with FPGA platform. We have
support for PCIe bus, which is used on FPGA prototyping.The host side of USBSS-DRD controller is compliant with XHCI

For HCs that have local memory, replace the current DMA API usage with
a genalloc generic allocator to manage the mappings for these devices.
To help users, introduce a new HCD API, usb_hcd_setup_local_mem() that
will setup up the genalloc backing up the device local memory. It will
be used in subsequent patches. This is in preparation for dropping
the existing "coherent" dma mem declaration APIs. The current
implementation was relying on a short circuit in the DMA API that in
the end, was acting as an allocator for these type of devices.Signed-off-by: Laurentiu Tudor

That makes the USB role switch support option visible and
selectable for the user. The class driver is also moved to
drivers/usb/roles/ directory.This will fix an issue that we have with the Intel USB role
switch driver on systems that don't have USB Type-C connectors:Intel USB role switch driver depends on the USB role switch
class as it should, but since there was no way for the user
to enable the USB role switch class, there was also no way
to select that driver. USB Type-C drivers select the USB
role switch class which makes the Intel USB role switch
driver available and therefore hides the problem.So in practice Intel USB role switch driver was depending on
USB Type-C drivers.Fixes: f6fb9ec02be1 ("usb: roles: Add Intel xHCI USB role switch driver")

Various Intel SoCs (Cherry Trail, Broxton and others) have an internal USB
role switch for swiching the OTG USB data lines between the xHCI host
controller and the dwc3 gadget controller.Note on some Cherry Trail systems there is ACPI/AML code listening to
edge interrupts on the id-pin (through an _AIE ACPI method) and switching
the role between ROLE_HOST and ROLE_NONE based on the id-pin. Note it does
not set the role to ROLE_DEVICE, because device-mode is usually not used
under Windows.The presence of AML code which modifies the cfg0 reg (on some systems)
means that our read/write/modify of cfg0 may race with the AML code
doing the same to avoid this we take the global ACPI lock while doing
the read/write/modify.Signed-off-by: Hans de Goede

USB role switch is a device that can be used to choose the
data role for USB connector. With dual-role capable USB
controllers, the controller itself will be the switch, but
on some platforms the USB host and device controllers are
separate IPs and there is a mux between them and the
connector. On those platforms the mux driver will need to
register the switch.With USB Type-C connectors, the host-to-device relationship
is negotiated over the Configuration Channel (CC). That
means the USB Type-C drivers need to be in control of the
role switch. The class provides a simple API for the USB
Type-C drivers for the control.For other types of USB connectors (mainly microAB) the class
provides user space control via sysfs attribute file that
can be used to request role swapping from the switch.Reviewed-by: Hans de Goede

The three options USB_ARCH_HAS_{EHCI,OHCI,XHCI} are all well beyond
their recommended shelf life. They have caused numerous build failures
over the years because they are never completely correct, and with
the move to splitting out the platform specific back-ends out of the
driver, there is no real need for them any more. Also, the use of making
USB_ARCH_HAS_HCD depend on it is questionable since one can always enable
dummy_hc these days.This patch enables them unconditionally for all platforms and
architectures, which means it is now possible to build host controller
drivers for machines that are known not to come with this hardware,
but that is just how we treat most other drivers.In order to minimise the impact on existing architecture code and
defconfig files, all the Kconfig are left present for now. All platforms
that currently do 'select USB_ARCH_HAS_*' should subsequently be changed
not to select that. All drivers depending on USB_ARCH_HAS_HCD should
be changed to depend on USB_SUPPORT instead.Signed-off-by: Arnd Bergmann

space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used
with a mainline kernel. We have not been able to find anyone
interested in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra+ A handful of other things that I haven't described above."
Fix up some conflicts with the staging tree (and because nxp4008 was
removed)* tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (184 commits)
