Some regulators have different settling times for voltage increases and
decreases. Add DT properties to define separate settling times for up-
and downward voltage changes.

(cherry picked from commit 543853de35)
Some regulators (some PWM regulators) have the voltage transition
exponentially. On such cases, the settling time for voltage change
is treated as constant time.
Add DT property for providing the settling time for any level of
voltage change for non-linear voltage change.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've followed up to support some generic features such
as cgroup, block reservation, linking fscrypt_ops, delivering
write_hints, and some ioctls. And, we could fix some corner cases in
terms of power-cut recovery and subtle deadlocks.
Enhancements:
- bitmap operations to handle NAT blocks
- readahead to improve readdir speed
- switch to use fscrypt_*
- apply write hints for direct IO
- add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid
- modify b_avail and b_free to consider root reserved blocks
- support cgroup writeback
- support FIEMAP_FLAG_XATTR for fibmap
- add F2FS_IOC_PRECACHE_EXTENTS to pre-cache extents
- add F2FS_IOC_{GET/SET}_PIN_FILE to pin LBAs for data blocks
- support inode creation time
Bug fixs:
- sysfile-based quota operations
- memory footprint accounting
- allow to write data on partial preallocation case
- fix deadlock case on fallocate
- fix to handle fill_super errors
- fix missing inode updates of fsync'ed file
- recover renamed file which was fsycn'ed before
- drop inmemory pages in corner error case
- keep last_disk_size correctly
- recover missing i_inline flags during roll-forward
Various clean-up patches were added as well"

Add a new kernel parameter to override the default behavior related to
the decision whether to indicate stack as non-executable or executable
(regardless of PT_GNU_STACK entry or CPU RIXI support) in function
mips_elf_read_implies_exec().
Allowed values:
noexec=on: force indicating non-exec stack & heap
noexec=off: force indicating executable stack & heap
If this parameter is omitted, kernel behavior remains the same as it
was before this patch is applied.
This functionality is convenient during debugging and is especially
useful for Android development where indication of non-executable
stack is required.
NOTE: Using noexec=on on a system without CPU XI support is not
recommended since there is no actual HW support that provide
non-executable stack and heap. Use only for debugging purposes and
not in a production environment.

Add an `ieee754=' kernel parameter to control IEEE Std 754 conformance
mode.
Use separate flags copied from the respective CPU feature flags, and
adjusted according to the conformance mode selected, to make binaries
requesting individual NaN encoding modes accepted or rejected as needed.
Update the initial setting for FCSR and, in the full FPU emulation mode,
its read-only mask accordingly. Accept the mode selection requested for
legacy processors as well.
As with the EF_MIPS_NAN2008 ELF file header flag adjust both ABS2008 and
NAN2008 bits at the same time, to match the choice made for hardware
currently implemented.
