Add an operating-points-v2 table with all OPPs available for all silicon
revisions along with necessary data for use by ti-opp driver to selectively
enable the appropriate OPPs at runtime and handle voltage transitions

As we now need to define voltage ranges for each OPP, we define the
minimum and maximum voltage to match the ranges possible for AVS class0
voltage as defined by the DRA7/AM57 Data Manual, with the exception of
using a range for OPP_OD based on historical data to ensure that SoCs
from older lots still continue to boot, even though more optimal voltages
are now the standard. Once an AVS Class0 driver is in place it will be
possible for these OPP voltages to be adjusted to any voltage within the
provided range.

Dave Gerlach fae3a9f023 ARM: dts: dra7: Add ti,secure-ram node to ocmcram1 node
Secure variants of DRA7xx and AM57xx SoCs may need to reserve a region
of the SRAM for use by secure software. To account for this, add a child
node to the ocmcram1 node that will act as a placeholder at the start
of the SRAM for the reserved region of memory that may be required
by secure services. The node is added with size 0 so that by default
parts will have the full space available but the bootloader or board dts
file is able to resize the node as needed depending on how much reserved
space is needed, if any, so end users of the ocmcram1 region on HS parts
must be aware that a smaller amount of SRAM than expected may be available.

Linus Torvalds 7e0fb73c52 Merge branch 'hash' of git://ftp.sciencehorizons.net/linux
Pull string hash improvements from George Spelvin:
 "This series does several related things:

   - Makes the dcache hash (fs/namei.c) useful for general kernel use.

     (Thanks to Bruce for noticing the zero-length corner case)

   - Converts the string hashes in <linux/sunrpc/svcauth.h> to use the
     above.

   - Avoids 64-bit multiplies in hash_64() on 32-bit platforms.  Two
     32-bit multiplies will do well enough.

   - Rids the world of the bad hash multipliers in hash_32.

     This finishes the job started in commit 689de1d6ca ("Minimal
     fix-up of bad hashing behavior of hash_64()")

     The vast majority of Linux architectures have hardware support for
     32x32-bit multiply and so derive no benefit from "simplified"
     multipliers.

     The few processors that do not (68000, h8/300 and some models of
     Microblaze) have arch-specific implementations added.  Those
     patches are last in the series.

   - Overhauls the dcache hash mixing.

     The patch in commit 0fed3ac866 ("namei: Improve hash mixing if
     CONFIG_DCACHE_WORD_ACCESS") was an off-the-cuff suggestion.
     Replaced with a much more careful design that's simultaneously
     faster and better.  (My own invention, as there was noting suitable
     in the literature I could find.  Comments welcome!)

   - Modify the hash_name() loop to skip the initial HASH_MIX().  This
     would let us salt the hash if we ever wanted to.

   - Sort out partial_name_hash().

     The hash function is declared as using a long state, even though
     it's truncated to 32 bits at the end and the extra internal state
     contributes nothing to the result.  And some callers do odd things:

      - fs/hfs/string.c only allocates 32 bits of state
      - fs/hfsplus/unicode.c uses it to hash 16-bit unicode symbols not bytes

   - Modify bytemask_from_count to handle inputs of 1..sizeof(long)
     rather than 0..sizeof(long)-1.  This would simplify users other
     than full_name_hash"

  Special thanks to Bruce Fields for testing and finding bugs in v1.  (I
  learned some humbling lessons about "obviously correct" code.)

  On the arch-specific front, the m68k assembly has been tested in a
  standalone test harness, I've been in contact with the Microblaze
  maintainers who mostly don't care, as the hardware multiplier is never
  omitted in real-world applications, and I haven't heard anything from
  the H8/300 world"

  Change hash_64() return value to 32 bits
  <linux/sunrpc/svcauth.h>: Define hash_str() in terms of hashlen_string()
  fs/namei.c: Add hashlen_string() function
  Pull out string hash to <linux/stringhash.h>

George Spelvin 4684fe9530 h8300: Add <asm/hash.h>
This will improve the performance of hash_32() and hash_64(), but due
to complete lack of multi-bit shift instructions on H8, performance will
still be bad in surrounding code.

Designing H8-specific hash algorithms to work around that is a separate
project.  (But if the maintainers would like to get in touch...)
