staging: dwc2: when dma is disabled, clear hcd->self.uses_dma
When dma is disabled inside dwc2 (because the hardware does not support
it, or the code was changed to disable it for testing), let the usb core
know about this by clearing hcd->self.uses_dma.
By default, the usb core assumes that dma is used when a dma_mask is
set, but this might not always match the dma_enable value in dwc2. To
prevent problems resulting from a mismatch, better to explicitely
disable dma in this case (though everything seemed to work with the
wrong value of uses_dma as well, probably only resulted in some unneeded
work).
staging: dwc2: disable dma when no dma_mask was setup
If the platform or bus driver failed to setup a dma_mask, but the
hardware advertises support for DMA, before DMA would be enabled in
dwc2, but disabled in the usb core, making all connectivity break.
With this commit, the dwc2 driver will emit a warning and fall back to
slave mode in this case.
Note that since commit 642f2ec (staging: dwc2: Fix dma-enabled platform
devices using a default dma_mask) the platform bindings make sure a DMA
mask is always present, but having this check here anyway is probably a
good from a defensive programming standpoint (in case of changes to
platform.c or addition of new glue layers).

staging: dwc2: add driver parameter to set AHB config register value
The dwc2 driver sets the value of the DWC2 GAHBCFG register to 0x6,
which is GAHBCFG_HBSTLEN_INCR4. But different platforms may require
different values. In particular, the Broadcom 2835 SOC used in the
Raspberry Pi needs a value of 0x10, otherwise the DWC2 controller
stops working after a short period of heavy USB traffic.
So this patch adds another driver parameter named 'ahbcfg'. The
default value is 0x6. Any platform needing a different value should
add a DT attribute to set it.
This patch also removes the 'ahb_single' driver parameter, since
that bit can now be set using 'ahbcfg'.
This patch does not add DT support to platform.c, I will leave that
to whoever owns the first platform that needs a non-default value.

staging: dwc2: refactor dwc2_host_complete()
The parameters to dwc2_host_complete() didn't make much sense.
The 'context' parameter always came from the ->priv member of the
'dwc2_urb' parameter, and both of those always came from a struct
dwc2_qtd. So just pass in the struct dwc2_qtd instead.
This also allows us to null out the dwc2_qtd->urb member after it
is freed, which the calling code forgot to do in several places,
causing random driver crashes from dereferencing the freed pointer.
This also requires the calls to dwc2_hc_handle_tt_clear() to be
moved before the calls to dwc2_host_complete(), otherwise that
routine would do nothing because dwc2_qtd->urb has already been
freed.

staging: android: binder: fix binder interface for 64bit compat layer
The changes in this patch will fix the binder interface for use on 64bit
machines and stand as the base of the 64bit compat support. The changes
apply to the structures that are passed between the kernel and
userspace.
Most of the changes applied mirror the change to struct binder_version
where there is no need for a 64bit wide protocol_version(on 64bit
machines). The change inlines with the existing 32bit userspace(the
structure has the same size) and simplifies the compat layer such that
the same handler can service the BINDER_VERSION ioctl.
Other changes make use of kernel types as well as user-exportable ones
and fix format specifier issues.
