2024-01-01pinctrl: starfive: jh7100: ignore disabled device tree nodesNam Cao1-2/+2
commit 5c584f175d32f9cc66c909f851cd905da58b39ea upstream. The driver always registers pin configurations in device tree. This can cause some inconvenience to users, as pin configurations in the base device tree cannot be disabled in the device tree overlay, even when the relevant devices are not used. Ignore disabled pin configuration nodes in device tree.

2023-09-12pinctrl: starfive: jh7110: Fix failure to set irq after CONFIG_PM is enabledHal Feng1-2/+0
The issue was found when we enabled CONFIG_PM and tested edge events using libgpiod. > # gpiomon -r gpiochip0 55 > gpiomon: error waiting for events: Permission denied `gpiomon` will call irq_chip_pm_get() and then call pm_runtime_resume_and_get() if (IS_ENABLED(CONFIG_PM) && sfp->gc.irq.domain->pm_dev). pm_runtime_resume_and_get() will fail if the runtime pm of pinctrl device is disabled. As we expect the pinctrl driver can be always working and never suspend during runtime, unset sfp->gc.irq.domain->pm_dev to make sure pm_runtime_resume_and_get() won't be called when setting irq.

2023-07-20pinctrl: Explicitly include correct DT includesRob Herring3-7/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
