2020-10-27dt-bindings: More whitespace clean-ups in schema filesRob Herring1-3/+3
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).

2020-07-23dt-bindings: rng: add RNGB compatibles for i.MX6 SoCsHoria Geantă1-0/+3
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.

2020-06-11dt-bindings: Remove more cases of 'allOf' containing a '$ref'Rob Herring1-4/+2
Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$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. Signed-off-by: Rob Herring <robh@kernel.org>

2020-03-31dt-bindings: Add missing 'additionalProperties: false'Rob Herring2-0/+4
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.

Commit 0ed266d7ae5e ("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.

2019-09-05hwrng: timeriomem - relax check on memory resource sizeDaniel Mack1-1/+1
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.

Freescale i.MX21 and i.MX31 SoCs contain a Random Number Generator Accelerator module (RNGA), which is replaced by RNGB and RNGC modules on later i.MX SoC series, the change adds a new compatible property to describe the controller. Since all versions of Freescale RNG modules are legacy, apparently the documentation file has no more potential for further extensions, nevertheless generalize it by removing explicit RNGC specifics.

Commit 52060836f79 ("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.
