pinctrl: qcom: spmi: fix debugfs drive strength

2024-12-05T13:02:47Z

commit 6bc0ebfb1d920f13c522545f114cdabb49e9408a upstream. Commit 723e8462a4fe ("pinctrl: qcom: spmi-gpio: Fix the GPIO strength mapping") fixed a long-standing issue in the Qualcomm SPMI PMIC gpio driver which had the 'low' and 'high' drive strength settings switched but failed to update the debugfs interface which still gets this wrong. Fix the debugfs code so that the exported values match the hardware settings. Note that this probably means that most devicetrees that try to describe the firmware settings got this wrong if the settings were derived from debugfs. Before the above mentioned commit the settings would have actually matched the firmware settings even if they were described incorrectly, but now they are inverted.

pinctrl: ocelot: fix system hang on level based interrupts

2024-10-12T20:04:38Z

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, ®); 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: stable@vger.kernel.org Signed-off-by: Sergey Matsievskiy Reviewed-by: Alexandre Belloni Link: https://lore.kernel.org/20241012105743.12450-2-matsievskiysv@gmail.com Signed-off-by: Linus Walleij

pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()

2024-10-11T19:54:58Z

'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(). Fix this by using kcalloc() instead of auto-managed devm_kcalloc().

pinctrl: sophgo: fix double free in cv1800_pctrl_dt_node_to_map()

2024-10-10T19:12:59Z

'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. Use kcalloc() instead of devm_kcalloc() as freeing is manually handled.
