Rob Herring 6ad8838de4 dt-bindings: More whitespace clean-ups in schema files
Clean-up incorrect indentation, extra spaces, and missing EOF newline in
schema files. Most of the clean-ups are for list indentation which
should always be 2 spaces more than the preceding keyword.

Found with yamllint (now integrated into the checks).

Horia Geantă b526ee38d1 dt-bindings: rng: add RNGB compatibles for i.MX6 SoCs
RNGB block is found in some i.MX6 SoCs - 6SL, 6SLL, 6ULL, 6ULZ.
Add corresponding compatible strings.

Note:

Several NXP SoC from QorIQ family (P1010, P1023, P4080, P3041, P5020)
also have a RNGB, however it's part of the CAAM
(Cryptograhic Accelerator and Assurance Module) crypto accelerator.
In this case, RNGB is managed in the caam driver
(drivers/crypto/caam/), since it's tightly related to
the caam "job ring" interface, not to mention CAAM internally relying on
RNGB as source of randomness.

On the other hand, the i.MX6 SoCs with RNGB have a DCP
(Data Co-Processor) crypto accelerator and this block and RNGB
are independent.

Rob Herring 086e9074f5 dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another round of 'allOf' removals that came in this cycle.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Rob Herring 7f464532b0 dt-bindings: Add missing 'additionalProperties: false'
Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

Tony Lindgren 0c0ef9ea6f hwrng: omap3-rom - Fix missing clock by probing with device tree
Commit 0ed266d7ae ("clk: ti: omap3: cleanup unnecessary clock aliases")
removed old omap3 clock framework aliases but caused omap3-rom-rng to
stop working with clock not found error.

Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.

Let's also add a proper device tree binding and keep it together with
the fix.

Daniel Mack 2a4bfd023f hwrng: timeriomem - relax check on memory resource size
The timeriomem_rng driver only accesses the first 4 bytes of the given
memory area and currently, it also forces that memory resource to be
exactly 4 bytes in size.

This, however, is problematic when used with device-trees that are
generated from things like FPGA toolchains, where the minimum size
of an exposed memory block may be something like 4k.

Hence, let's only check for what's needed for the driver to operate
properly; namely that we have enough memory available to read the
random data from.

Linus Torvalds 721afaa2ae ARM: Device-tree updates
As always, a large number of DT updates. Too many to enumerate them all,
 but at a glance:
 
 New SoCs introduced in this release:
 
  - Amlogic:
    + Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some set
      top boxes and other products.
 
  - Mediatek:
    + MT7623A, which is a flavor of the MT7623 family with other on-chip
      ethernet options.
 
  - Qualcomm:
    + SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845
      (Cortex-A75/A55 derivative) SoC that's one of the current high-end
      mobile SoCs.
 
      It's great to see mainline support for it. So far, you
      can't do much with it, since a lot of peripherals are not yet in the
      DTs but driver support for USB, GPU and other pieces are starting to
      trickle in. This might end up being a well-supported SoC upstream if
      the momentum keeps up.
 
  - Renesas:
    + R8A77990, a.k.a R-Car E3, a new automotive entertainment-targeted
      SoC. Currently only one Cortex-A53 CPU is enabled, we are eagerly
      awaiting more. So far, basic drivers such as serial, gpios, PMU and
      ethernet are enabled.
    + R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR
      GPU. Same here, basic set of drivers such as serial, gpios and ethernet
      enabled, and SMP support is also forthcoming.
 
  - STMicroelectronics:
    + STM32F469, very similar tih STM32F429 but with display support
 
 Enhancements to SoCs/platforms (DTS contents, some driver portions might
 not be in yet):
 
  - Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc
  - Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets
  - Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces
  - Marvell Berlin2CD: SMP support, thermal sensors
  - Mediatek MT7623: Highspeed DMA, audio support
  - Qualcomm IPQ8074 PCIe support, MSM8996 UFS support
  - Renesas: Watchdog and PMU support across many platforms
  - Rockchip RK3399: USB3 OTG support

Thomas Petazzoni 74d1cf4897 dt-bindings: rng: clocks property on omap_rng not always mandatory
Commit 52060836f7 ("dt-bindings: omap-rng: Document SafeXcel IP-76
device variant") update the omap_rng Device Tree binding to add support
for the IP-76 variation of the IP. As part of this change, a "clocks"
property was added, but is indicated as "Required", without indicated
it's actually only required for some compatible strings.

This commit fixes that, by explicitly stating that the clocks property
is only required with the inside-secure,safexcel-eip76 compatible
string.
