4 dayspinctrl: qcom: lpass-lpi: mark the GPIO controller as sleepingBartosz Golaszewski1-1/+1
commit ebc18e9854e5a2b62a041fb57b216a903af45b85 upstream. The gpio_chip settings in this driver say the controller can't sleep but it actually uses a mutex for synchronization.

10 dayspinctrl: qcom: msm: Fix deadlock in pinmux configurationPraveen Talari1-1/+1
[ Upstream commit 1c2e70397b4125022dba80f6111271a37fb36bae ] Replace disable_irq() with disable_irq_nosync() in msm_pinmux_set_mux() to prevent deadlock when wakeup IRQ is triggered on the same GPIO being reconfigured. The issue occurs when a wakeup IRQ is triggered on a GPIO and the IRQ handler attempts to reconfigure the same GPIO's pinmux. In this scenario, msm_pinmux_set_mux() calls disable_irq() which waits for the currently running IRQ handler to complete, creating a circular dependency that results in deadlock. Using disable_irq_nosync() avoids waiting for the IRQ handler to complete, preventing the deadlock condition while still properly disabling the interrupt during pinmux reconfiguration.

2025-07-17pinctrl: qcom: msm: mark certain pins as invalid for interruptsBartosz Golaszewski1-0/+20
commit 93712205ce2f1fb047739494c0399a26ea4f0890 upstream. On some platforms, the UFS-reset pin has no interrupt logic in TLMM but is nevertheless registered as a GPIO in the kernel. This enables the user-space to trigger a BUG() in the pinctrl-msm driver by running, for example: `gpiomon -c 0 113` on RB2. The exact culprit is requesting pins whose intr_detection_width setting is not 1 or 2 for interrupts. This hits a BUG() in msm_gpio_irq_set_type(). Potentially crashing the kernel due to an invalid request from user-space is not optimal, so let's go through the pins and mark those that would fail the check as invalid for the irq chip as we should not even register them as available irqs. This function can be extended if we determine that there are more corner-cases like this.

2025-06-04pinctrl: qcom/msm: Convert to platform remove callback returning voidUwe Kleine-König49-51/+49
[ Upstream commit 22ee670a8ad3ec7cd9d872d4512fe8797130e191 ] The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). To convert all those qcom pinctrl drivers, make msm_pinctrl_remove() return void (instead of zero) and use .remove_new in all drivers.

2025-04-25pinctrl: qcom: Clear latched interrupt status when changing IRQ typeStephan Gerhold1-6/+6
commit e225128c3f8be879e7d4eb71a25949e188b420ae upstream. When submitting the TLMM test driver, Bjorn reported that some of the test cases are failing for GPIOs that not are backed by PDC (i.e. "non-wakeup" GPIOs that are handled directly in pinctrl-msm). Basically, lingering latched interrupt state is still being delivered at IRQ request time, e.g.: ok 1 tlmm_test_silent_rising tlmm_test_silent_falling: ASSERTION FAILED at drivers/pinctrl/qcom/tlmm-test.c:178 Expected atomic_read(&priv->intr_count) == 0, but atomic_read(&priv->intr_count) == 1 (0x1) not ok 2 tlmm_test_silent_falling tlmm_test_silent_low: ASSERTION FAILED at drivers/pinctrl/qcom/tlmm-test.c:178 Expected atomic_read(&priv->intr_count) == 0, but atomic_read(&priv->intr_count) == 1 (0x1) not ok 3 tlmm_test_silent_low ok 4 tlmm_test_silent_high Whether to report interrupts that came in while the IRQ was unclaimed doesn't seem to be well-defined in the Linux IRQ API. However, looking closer at these specific cases, we're actually reporting events that do not match the interrupt type requested by the driver: 1. After "ok 1 tlmm_test_silent_rising", the GPIO is in low state and configured for IRQF_TRIGGER_RISING. 2. (a) In preparation for "tlmm_test_silent_falling", the GPIO is switched to high state. The rising interrupt gets latched. (b) The GPIO is re-configured for IRQF_TRIGGER_FALLING, but the latched interrupt isn't cleared. (c) The IRQ handler is called for the latched interrupt, but there wasn't any falling edge. 3. (a) For "tlmm_test_silent_low", the GPIO remains in high state. (b) The GPIO is re-configured for IRQF_TRIGGER_LOW. This seems to result in a phantom interrupt that gets latched. (c) The IRQ handler is called for the latched interrupt, but the GPIO isn't in low state. 4. (a) For "tlmm_test_silent_high", the GPIO is switched to low state. (b) This doesn't result in a latched interrupt, because RAW_STATUS_EN was cleared when masking the level-triggered interrupt. Fix this by clearing the interrupt state whenever making any changes to the interrupt configuration. This includes previously disabled interrupts, but also any changes to interrupt polarity or detection type. With this change, all 16 test cases are now passing for the non-wakeup GPIOs in the TLMM.

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.

commit 8da86499d4cd125a9561f9cd1de7fba99b0aecbf upstream. The SPMI GPIO driver assumes that the parent device is an SPMI device and accesses random data when backcasting the parent struct device pointer for non-SPMI devices. Fortunately this does not seem to cause any issues currently when the parent device is an I2C client like the PM8008, but this could change if the structures are reorganised (e.g. using structure randomisation). Notably the interrupt implementation is also broken for non-SPMI devices. Also note that the two GPIO pins on PM8008 are used for interrupts and reset so their practical use should be limited. Drop the broken GPIO support for PM8008 for now.

2023-10-16pinctrl: qcom: lpass-lpi: fix concurrent register updatesKrzysztof Kozlowski1-6/+11
The Qualcomm LPASS LPI pin controller driver uses one lock for guarding Read-Modify-Write code for slew rate registers. However the pin configuration and muxing registers have exactly the same RMW code but are not protected. Pin controller framework does not provide locking here, thus it is possible to trigger simultaneous change of pin configuration registers resulting in non-atomic changes. Protect from concurrent access by re-using the same lock used to cover the slew rate register. Using the same lock instead of adding second one will make more sense, once we add support for newer Qualcomm SoC, where slew rate is configured in the same register as pin configuration/muxing.

interrupt targets SA8775 and newer target have added support for an increased number of interrupt targets. To implement this change, the intr_target field, which is used to configure the interrupt target in the interrupt configuration register is increased from 3 bits to 4 bits. In accordance to these updates, a new intr_target_width member is introduced in msm_pingroup structure. This member stores the value of width of intr_target field in the interrupt configuration register. This value is used to dynamically calculate and generate mask for setting the intr_target field. By default, this mask is set to 3 bit wide, to ensure backward compatibility with the older targets.

2023-07-20pinctrl: Explicitly include correct DT includesRob Herring4-4/+4
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.

2023-03-29pinctrl: qcom: Support OUTPUT_ENABLE; deprecate INPUT_ENABLEDouglas Anderson1-5/+31
The Qualcomm pinctrl driver has been violating the documented meaning of PIN_CONFIG_INPUT_ENABLE. That documentation says: Note that this does not affect the pin's ability to drive output. ...yet the Qualcomm driver's sole action when asked to "enable input" on a pin is to disable its output. The Qualcomm driver's implementation stems from the fact that "output-disable" is a "new" property from 2017. It was introduced in commit 425562429d4f ("pinctrl: generic: Add output-enable property"). The "input-enable" handling in Qualcomm drivers is from 2015 introduced in commit 407f5e392f9c ("pinctrl: qcom: handle input-enable pinconf property"). Let's change the Qualcomm driver to move us in the right direction. As part of this: 1. We'll now support PIN_CONFIG_OUTPUT_ENABLE 2. We'll still support using PIN_CONFIG_INPUT_ENABLE to disable a pin's output (in violation of the docs) with a big comment in the code. This is needed because old device trees have "input-enable" in them and, in some cases, people might need the old behavior. While we could programmatically change all old device trees, it doesn't really hurt to keep supporting the old behavior and we're _supposed_ to try to be compatible with old device trees anyway. It can also be noted that the PIN_CONFIG_INPUT_ENABLE handling code seems to have purposefully ignored its argument. That means that old boards that had _either_ "input-disable" or "input-enable" in them would have had the effect of disabling a pin's output. While we could change this behavior, since we're only leaving the PIN_CONFIG_INPUT_ENABLE there for backward compatibility we might as well be fully backward compatible. NOTE: despite the fact that we'll still support PIN_CONFIG_INPUT_ENABLE for _setting_ config, we take it away from msm_config_group_get(). This appears to be only used for populating debugfs and fixing debugfs to "output enabled" where relevant instead of "input enabled" makes more sense and has more truthiness.
