2025-07-01dt-bindings: mfd: adp5585: ease on the required propertiesNuno Sá
It is not mandatory to use all the capabilities of the device. One can very well only use it as a gpio controller without the PWM support. This will be even more evident when support for the matrix keymap is added. Hence drop the requirements for PWM and GPIO.

2025-06-20gpio: sysfs: remove the mockdev pointer from struct gpio_deviceBartosz Golaszewski
The usage of the mockdev pointer in struct gpio_device is limited to the GPIO sysfs code. There's no reason to keep it in this top-level structure. Create a separate structure containing the reference to the GPIO device and the dummy class device that will be passed to device_create_with_groups(). The !gdev->mockdev checks can be removed as long as we make sure that all operations on the GPIO class are protected with the sysfs lock.

2025-06-17dt-bindings: gpio: gpio-xilinx: Mark clocks as required propertyMichal Simek
On Microblaze platforms there is no need to handle clocks because the system is starting with clocks enabled (can be described via fixed clock node or clock-frequency property or not described at all). With using soft IPs with SOC platforms there is mandatory to handle clocks as is explained in commit 60dbdc6e08d6 ("dt-bindings: net: emaclite: Add clock support"). That's why make clock as required in dt binding because it is present in both configurations and should be described even there is no way how to handle it on Microblaze systems. There is also need to describe missing axi gpio clock in fpga-region.yaml not to introduce new error when make dt_binding_check runs.
