2020-03-12dt-bindings: i2c: i2c-rk3x: add description for rk3036Johan Jonker1-0/+4
The description below is already in use for rk3036.dtsi, but was somehow never added to a document, so add "rockchip,rk3036-i2c", "rockchip,rk3288-i2c" for i2c nodes on a rk3036 platform to i2c-rk3x.yaml. Signed-off-by: Johan Jonker <[email protected]> Signed-off-by: Rob Herring <[email protected]>

Current dts files with 'i2c' nodes are manually verified. In order to automate this process i2c-rk3x.txt has to be converted to yaml. In the new setup i2c-rk3x.yaml will inherit properties from i2c-controller.yaml. Also change document name in MAINTAINERS.

2020-03-06dt-bindings: arm: Fixup the DT bindings for hierarchical PSCI statesUlf Hansson1-15/+13
The hierarchical topology with power-domain should be described through child nodes, rather than as currently described in the PSCI root node. Fix this by adding a patternProperties with a corresponding reference to the power-domain DT binding. Additionally, update the example to conform to the new pattern, but also to the adjusted domain-idle-state DT binding.

2020-02-26of: unittest: annotate warnings triggered by unittestFrank Rowand1-30/+345
Some tests in the devicetree unittests result in printk messages from the code being tested. It can be difficult to determine whether the messages are the result of unittest or are potentially reporting bugs that should be fixed. The most recent example of a person asking whether to be concerned about these messages is [1]. Add annotations for all messages triggered by unittests, except KERN_DEBUG messages. (KERN_DEBUG is a special case due to the possible interaction of CONFIG_DYNAMIC_DEBUG.) The format of the annotations is expected to change when unittests are converted to use the kunit infrastructure when the broader testing community has an opportunity to discuss the implementation of annotations of test triggered messages.

Certain SoCs need to support a large amount of reserved memory regions. For example, Qualcomm's SM8150 SoC requires that 20 regions of memory be reserved for a variety of reasons (e.g. loading a peripheral subsystem's firmware image into a particular space). When adding more reserved memory regions to cater to different usecases, the remaining number of reserved memory regions--12 to be exact--becomes too small.
