2024-10-12pinctrl: ocelot: fix system hang on level based interruptsSergey Matsievskiy1-4/+4
The current implementation only calls chained_irq_enter() and chained_irq_exit() if it detects pending interrupts. ``` for (i = 0; i < info->stride; i++) { uregmap_read(info->map, id_reg + 4 * i, &reg); if (!reg) continue; chained_irq_enter(parent_chip, desc); ``` However, in case of GPIO pin configured in level mode and the parent controller configured in edge mode, GPIO interrupt might be lowered by the hardware. In the result, if the interrupt is short enough, the parent interrupt is still pending while the GPIO interrupt is cleared; chained_irq_enter() never gets called and the system hangs trying to service the parent interrupt. Moving chained_irq_enter() and chained_irq_exit() outside the for loop ensures that they are called even when GPIO interrupt is lowered by the hardware. The similar code with chained_irq_enter() / chained_irq_exit() functions wrapping interrupt checking loop may be found in many other drivers: ``` grep -r -A 10 chained_irq_enter drivers/pinctrl ``` Cc: [email protected] Signed-off-by: Sergey Matsievskiy <[email protected]> Reviewed-by: Alexandre Belloni <[email protected]> Link: https://lore.kernel.org/[email protected] Signed-off-by: Linus Walleij <[email protected]>

'new_map' is allocated using devm_* which takes care of freeing the allocated data on device removal, call to .dt_free_map = pinconf_generic_dt_free_map double frees the map as pinconf_generic_dt_free_map() calls pinctrl_utils_free_map().

'map' is allocated using devm_* which takes care of freeing the allocated data, but in error paths there is a call to pinctrl_utils_free_map() which also does kfree(map) which leads to a double free.

2024-09-30pinctrl: intel: platform: fix error path in device_for_each_child_node()Javier Carrasco1-2/+1
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 Gerhold1-1/+3
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.
