dt-bindings: Drop redundant minItems/maxItems

2021-06-21T19:56:46+00:00

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

dt-bindings: Add missing array size constraints

2021-01-11T23:42:25+00:00

DT properties which can have multiple entries need to specify what the entries are and define how many entries there can be. In the case of only a single entry, just 'maxItems: 1' is sufficient. Add the missing entry constraints. These were found with a modified meta-schema. Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.

dt-bindings: Fix JSON pointers

2020-12-18T21:14:44+00:00

The correct syntax for JSON pointers begins with a '/' after the '#'. Without a '/', the string should be interpreted as a subschema identifier. The jsonschema module currently doesn't handle subschema identifiers and incorrectly allows JSON pointers to begin without a '/'. Let's fix this before it becomes a problem when jsonschema module is fixed.

dt-bindings: More whitespace clean-ups in schema files

2020-10-26T21:13:56+00:00

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).

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". This allows for better timeout detections - new driver for Mellanox Bluefield - massive refactoring of the Tegra driver - EEPROMs recognized by the at24 driver can now have custom names - rest is driver updates * 'i2c/for-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (80 commits) Documentation: i2c: add testunit docs to index i2c: tegra: Improve driver module description i2c: tegra: Clean up whitespaces, newlines and indentation i2c: tegra: Clean up and improve comments i2c: tegra: Clean up printk messages i2c: tegra: Clean up variable names i2c: tegra: Improve formatting of variables i2c: tegra: Check errors for both positive and negative values i2c: tegra: Factor out hardware initialization into separate function i2c: tegra: Factor out register polling into separate function i2c: tegra: Factor out packet header setup from tegra_i2c_xfer_msg() i2c: tegra: Factor out error recovery from tegra_i2c_xfer_msg() i2c: tegra: Rename wait/poll functions i2c: tegra: Remove "dma" variable from tegra_i2c_xfer_msg() i2c: tegra: Remove redundant check in tegra_i2c_issue_bus_clear() i2c: tegra: Remove likely/unlikely from the code i2c: tegra: Remove outdated barrier() i2c: tegra: Clean up variable types i2c: tegra: Reorder location of functions in the code i2c: tegra: Clean up probe function ...
