2022-01-02dt-bindings: pinctrl: mt8195: add wrapping node of pin configurationsTinghan Shen1-150/+188
On mt8195, the pinctrl node has pinctrl groups to group pin configurations by users' need. In each pinctrl group, it has subnode(s) to list pins needed and pin configurations. By supporting multiple subnodes, we can configure different pin characteristics (driving/pull-up/pull-down/etc.) in a pinctrl group. Update pinctrl-mt8195.yaml to add subnode in pinctrl groups and an example to illustrate the usage.

2021-12-25pinctrl: samsung: Use platform_get_irq_optional() to get the interruptLad Prabhakar1-4/+5
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_optional().

2021-12-02pinctrl/rockchip: fix gpio device creationJohn Keeping1-1/+1
GPIO nodes are not themselves busses, so passing rockchip_bank_match here is wrong. Passing NULL instead uses the standard bus match table which is more appropriate. devm_of_platform_populate() shows that this is the normal way to call of_platform_populate() from a device driver, so in order to match that more closely also add the pinctrl device as the parent for the newly created GPIO controllers. Specifically, using the wrong match here can break dynamic GPIO hogs as marking the GPIO bank as a bus means that of_platform_notify() will set OF_POPULATED on new child nodes and if this happens before of_gpio_notify() is called then the new hog will be skipped as OF_POPULATED is already set.
