Arnd Bergmann f22940b795 Driver changes for ti-sysc for v5.7 merge window
Driver changes for ti-sysc interconnect target module driver mostly
 to be able to probe display subsystem (DSS) without platform data:
 
 - Rename clk_enable/disable quirks to less confusing pre and post
   reset quirks
 
 - Enable module reset to work with modules with no sysconfig register
 
 - Also consider non-existing module register when matching quirks
 
 - Don't warn with nested ti-sysc devices
 
 - Implement basic SoC revision handling
 
 - Detect DSS related devices
 
 - Implement DSS reset quirks
 
 Note that there is also a DSS driver specific probe fix to allow
 probing devices configured for interconnect target module data that
 was agreed to be merged along with the ti-sysc driver changes.
 
 And then there also changes to handle RTC, EDMA and PRUSS:
 
 - Add module unlock quirk for RTC
 
 - Detect EDMA modules
 
 - Add support for handling PRUSS

Roger Quadros 4d0dd3802e dt-bindings: bus: ti-sysc: Add support for PRUSS SYSC type
The PRUSS module has a SYSCFG which is unique. The SYSCFG
has two additional unique fields called STANDBY_INIT and
SUB_MWAIT in addition to regular IDLE_MODE and STANDBY_MODE
fields. Add the bindings for this new sysc type.

Masahiro Yamada eccbde4f6c kbuild: remove wrong documentation about mandatory-y
This sentence does not make sense in the section about mandatory-y.

This seems to be a copy-paste mistake of commit fcc8487d47 ("uapi:
export all headers under uapi directories").

The correct description would be "The convention is to list one
mandatory-y per line ...".

I just removed it instead of fixing it. If such information is needed,
it could be commented in include/asm-generic/Kbuild and
include/uapi/asm-generic/Kbuild.

Kees Cook adc10f5b0a docs: Fix empty parallelism argument
When there was no parallelism (no top-level -j arg and a pre-1.7
sphinx-build), the argument passed would be empty ("") instead of just
being missing, which would (understandably) badly confuse sphinx-build.
Fix this by removing the quotes.

Pull arm64 fixes from Will Deacon:
 "It's all straightforward apart from the changes to mmap()/mremap() in
  relation to their handling of address arguments from userspace with
  non-zero tag bits in the upper byte.

  The change to brk() is necessary to fix a nasty user-visible
  regression in malloc(), but we tightened up mmap() and mremap() at the
  same time because they also allow the user to create virtual aliases
  by accident. It's much less likely than brk() to matter in practice,
  but enforcing the principle of "don't permit the creation of mappings
  using tagged addresses" leads to a straightforward ABI without having
  to worry about the "but what if a crazy program did foo?" aspect of
  things.

  Summary:

   - Fix regression in malloc() caused by ignored address tags in brk()

   - Add missing brackets around argument to untagged_addr() macro

Add append value operator "+=" support to bootconfig syntax.
With this operator, user can add new value to the key as
an entry of array instead of overwriting.
For example,

  foo = bar
  ...
  foo += baz

Then the key "foo" has "bar" and "baz" values as an array.

Currently, bootconfig adds a new value on the existing key to the tail of an
array. But this looks a bit confusing because an admin can easily rewrite
the original value in the same config file.

This rejects the following value re-definition.

  key = value1
  ...
  key = value2

You should rewrite value1 to value2 in this case.

Also tools/bootconfig treats wrong size or wrong checksum or
parse error as an error, because if there is a bootconfig magic

The bootconfig magic word is "#BOOTCONFIG\n", 12 bytes word.
Thus the block image of the initrd file with bootconfig is
as follows.

Catalin Marinas dcde237319 mm: Avoid creating virtual address aliases in brk()/mmap()/mremap()
Currently the arm64 kernel ignores the top address byte passed to brk(),
mmap() and mremap(). When the user is not aware of the 56-bit address
limit or relies on the kernel to return an error, untagging such
pointers has the potential to create address aliases in user-space.
Passing a tagged address to munmap(), madvise() is permitted since the
tagged pointer is expected to be inside an existing mapping.

The current behaviour breaks the existing glibc malloc() implementation
which relies on brk() with an address beyond 56-bit to be rejected by
the kernel.

Remove untagging in the above functions by partially reverting commit
ce18d171cb ("mm: untag user pointers in mmap/munmap/mremap/brk"). In
addition, update the arm64 tagged-address-abi.rst document accordingly.

Maxime Ripard 854bdbae90 dt-bindings: media: csi: Fix clocks description
Commit 1de243b076 ("media: dt-bindings: media: sun4i-csi: Add compatible
for CSI1 on A10/A20") introduced support for the CSI1 controller on A10 and
A20 that unlike CSI0 doesn't have an ISP and therefore only have two
clocks, the bus and module clocks.

The clocks and clock-names properties have thus been modified to allow
either two or tree clocks. However, the current list has the ISP clock at
the second position, which means the bindings expects a list of either
bus and isp, or bus, isp and mod. The initial intent of the patch was
obviously to have bus and mod in the former case.

Let's fix the binding so that it validates properly.

Grygorii Strashko 867c185959 dt-bindings: net: mdio: remove compatible string from example
Remove vendor specific compatible string from example, otherwise DT YAML
schemas validation may trigger warnings specific to TI ti,davinci_mdio
and not to the generic MDIO example.

For example, the "bus_freq" is required for davinci_mdio, but not required for
generic mdio example. As result following warning will be produced:
 mdio.example.dt.yaml: mdio@5c030000: 'bus_freq' is a required property

Linus Torvalds ab02b61f24 Minor bug fixes for IPMI
I know this is late; I've been travelling and, well, I've been
 distracted.
 
 This is just a few bug fixes and adding i2c support to the IPMB driver,
 which is something I wanted from the beginning for it.  It would be
 nice for the people doing IPMB to get this in.
