This patch adds SoC-specific parameter to avoid reading/writing
specific registers wrongly if this driver runs on a SoC which doesn't
have dedicated pins (e.g. R-Car D3). This patch also changes the
value "has_otg" to "has_otg_pins" for slightly easier reading of
the code.

This patch adds binding for r8a77995 (R-Car D3). Since r8a77995 doesn't
have dedicated pins (ID, VBUS), this will match against the generic
fallback on R-Car D3.
For now, this driver doesn't support usb role swap for r8a77995.

The previous code assumed a channel has otg capability if a channel
has interrupt property. But, it is not good because:
- Battery charging feature also needs interrupt property.
- Some R-Car Gen3 SoCs (e.g. R-Car D3) don't have OTG capability.
So, this patch checks whether usb 2.0 host node has

The current hid-multitouch driver only allow the report of two
orientations, vertical and horizontal. We use the Azimuth orientation

If faddr2line is given a function name which is the

The following is a 'possible' way to add such functionality. I just
did what was easy and pre-allocated contiguous pages which are used
to populate the mapping. I did not use any of the higher order
allocators such as alloc_contig_range. Therefore, it is limited to
allocations of MAX_ORDER size.
Add the flag VM_CONTIG to vma structure to identify vmas which are
backed by contiguous memory allocations. This flag is not propogated
to child processes, so be sure to clear at fork time.

Add new MAP_CONTIG flag to mmap system call. Check for flag in normal
mmap flag processing. If present, pre-allocate a contiguous set of
pages to back the mapping. These pages will be used a fault time, and
the MAP_CONTIG flag implies populating the mapping at the mmap time.

perf stat --per-thread doesn't support outputting metrics, like IPC.
We should support this because it would allow easily to collect metrics
for different threads in applications.

Factor out the case of privileged root from the function
cap_bprm_set_creds() to make the latter easier to read and analyse.

In jffs2_do_setattr, we hold two mutexes which are
A) c->alloc_sem
B) f->sem
If new_metadata is error, then we release mutexes in bad sequence
which could cause ABAB deadlock.
This patch adjusts release sequence which could avoid deadlock.

The way the logic was presented, it was awkward to read and verify.
Invert the logic using DeMorgan's Law to be more easily able to read and
