2020-10-27dt-bindings: More whitespace clean-ups in schema filesRob Herring1-4/+4
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).

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: - if a host can be a client, too, the I2C core can now use it to emulate SMBus HostNotify support (STM32 and R-Car added this so far) - also for client mode, a testunit has been added. It can create rare situations on the bus, so host controllers can be tested - a binding has been added to mark the bus as "single-master".

2020-10-07dt-bindings: Add missing 'unevaluatedProperties'Rob Herring8-0/+16
This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.

The I2C controller in the JZ4770 SoC seems to work the exact same as in the JZ4780 SoC. We could use "ingenic,jz4780-i2c" as a fallback string in the Device Tree, but that would be awkward, since the JZ4780 is newer.

2020-05-30dt-bindings: i2c: Convert DW I2C slave to the DW I2C master exampleSerge Semin1-2/+2
dtc currently doesn't support I2C_OWN_SLAVE_ADDRESS flag set in the i2c "reg" property. If dtc finds an i2c-slave sub-node having an address higher than ten-bits wide it'll print an ugly warning: Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64: I2C bus unit address format error, expected "40000064" Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64:reg: I2C address must be less than 10-bits, got "0x40000064" In order to silence dtc up let's replace the corresponding DT binding example with a normal DW I2C master mode-based one. It's done by clearing the I2C_OWN_SLAVE_ADDRESS bit in the reg property and converting the sub-node to be compatible with normal EEPROM like "atmel,24c02". Just revert this commit when dtc is fixed.

2020-05-30dt-bindings: i2c: Convert DW I2C binding to DT schemaSerge Semin2-73/+154
Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces Synopsys DW I2C legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible either with generic DW I2C controller or with Microsemi Ocelot SoC I2C one, to have registers, interrupts and clocks properties. In addition the node may have clock-frequency, i2c-sda-hold-time-ns, i2c-scl-falling-time-ns and i2c-sda-falling-time-ns optional properties.

2020-05-03dt-bindings: Remove cases of 'allOf' containing a '$ref'Rob Herring1-5/+4
json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$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. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.
