2024-09-30pinctrl: intel: platform: fix error path in device_for_each_child_node()Javier Carrasco
The device_for_each_child_node() loop requires calls to fwnode_handle_put() upon early returns to decrement the refcount of the child node and avoid leaking memory if that error path is triggered. There is one early returns within that loop in intel_platform_pinctrl_prepare_community(), but fwnode_handle_put() is missing. Instead of adding the missing call, the scoped version of the loop can be used to simplify the code and avoid mistakes in the future if new early returns are added, as the child node is only used for parsing, and it is never assigned.

2024-09-02pinctrl: qcom: x1e80100: Bypass PDC wakeup parent for nowStephan Gerhold
On X1E80100, GPIO interrupts for wakeup-capable pins have been broken since the introduction of the pinctrl driver. This prevents keyboard and touchpad from working on most of the X1E laptops. So far we have worked around this by manually building a kernel with the "wakeup-parent" removed from the pinctrl node in the device tree, but we cannot expect all users to do that. Implement a similar workaround in the driver by clearing the wakeirq_map for X1E80100. This avoids using the PDC wakeup parent for all GPIOs and handles the interrupts directly in the pinctrl driver instead. The PDC driver needs additional changes to support X1E80100 properly. Adding a workaround separately first allows to land the necessary PDC changes through the normal release cycle, while still solving the more critical problem with keyboard and touchpad on the current stable kernel versions. Bypassing the PDC is enough for now, because we have not yet enabled the deep idle states where using the PDC becomes necessary.

2024-09-02pinctrl: madera: Simplify with dev_err_probe()Yan Zhen
Switch to use dev_err_probe() to simplify the error path and unify a message template. Using this helper is totally fine even if err is known to never be -EPROBE_DEFER. The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.

2024-08-24pinctrl: rockchip: correct RK3328 iomux width flag for GPIO2-B pinsHuang-Huang Bao
The base iomux offsets for each GPIO pin line are accumulatively calculated based off iomux width flag in rockchip_pinctrl_get_soc_data. If the iomux width flag is one of IOMUX_WIDTH_4BIT, IOMUX_WIDTH_3BIT or IOMUX_WIDTH_2BIT, the base offset for next pin line would increase by 8 bytes, otherwise it would increase by 4 bytes. Despite most of GPIO2-B iomux have 2-bit data width, which can be fit into 4 bytes space with write mask, it actually take 8 bytes width for whole GPIO2-B line. Commit e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328 GPIO2-B pins") wrongly set iomux width flag to 0, causing all base iomux offset for line after GPIO2-B to be calculated wrong. Fix the iomux width flag to IOMUX_WIDTH_2BIT so the offset after GPIO2-B is correctly increased by 8, matching the actual width of GPIO2-B iomux.
