2023-11-28mfd: qcom-spmi-pmic: Fix revid implementationJohan Hovold1-16/+53
commit 7b439aaa62fee474a0d84d67a25f4984467e7b95 upstream. The Qualcomm SPMI PMIC revid implementation is broken in multiple ways. First, it assumes that just because the sibling base device has been registered that means that it is also bound to a driver, which may not be the case (e.g. due to probe deferral or asynchronous probe). This could trigger a NULL-pointer dereference when attempting to access the driver data of the unbound device. Second, it accesses driver data of a sibling device directly and without any locking, which means that the driver data may be freed while it is being accessed (e.g. on driver unbind). Third, it leaks a struct device reference to the sibling device which is looked up using the spmi_device_from_of() every time a function (child) device is calling the revid function (e.g. on probe). Fix this mess by reimplementing the revid lookup so that it is done only at probe of the PMIC device; the base device fetches the revid info from the hardware, while any secondary SPMI device fetches the information from the base device and caches it so that it can be accessed safely from its children. If the base device has not been probed yet then probe of a secondary device is deferred.

2023-11-28mfd: qcom-spmi-pmic: Fix reference leaks in revid helperJohan Hovold1-13/+19
commit a0fa44c261e448c531f9adb3a5189a3520f3e316 upstream. The Qualcomm SPMI PMIC revid implementation is broken in multiple ways. First, it totally ignores struct device_node reference counting and leaks references to the parent bus node as well as each child it iterates over using an open-coded for_each_child_of_node(). Second, it leaks references to each spmi device on the bus that it iterates over by failing to drop the reference taken by the spmi_device_from_of() helper. Fix the struct device_node leaks by reimplementing the lookup using for_each_child_of_node() and adding the missing reference count decrements. Fix the sibling struct device leaks by dropping the unnecessary lookups of devices with the wrong USID. Note that this still leaves one struct device reference leak in case a base device is found but it is not the parent of the device used for the lookup. This will be addressed in a follow-on patch.

[ Upstream commit 831d1af85133e1763d41e20414912d9a1058ea72 ] Commit 9e86b2ad4c11 changed the channel used for HPDET detection (headphones vs lineout detection) from being hardcoded to ARIZONA_ACCDET_MODE_HPL (HP left channel) to it being configurable through arizona_pdata.hpdet_channel the DT/OF parsing added for filling arizona_pdata on devicetree platforms ensures that arizona_pdata.hpdet_channel gets set to ARIZONA_ACCDET_MODE_HPL when not specified in the devicetree-node. But on ACPI platforms where arizona_pdata is filled by arizona_spi_acpi_probe() arizona_pdata.hpdet_channel was not getting set, causing it to default to 0 aka ARIZONA_ACCDET_MODE_MIC. This causes headphones to get misdetected as line-out on some models. Fix this by setting hpdet_channel = ARIZONA_ACCDET_MODE_HPL.

As &chip->pm_irq_lock is acquired by pm8xxx_irq_handler() under irq context, other process context code should disable irq before acquiring the lock. Since .irq_set_type and .irq_get_irqchip_state callbacks are generally executed from process context without irq disabled by default, the same lock acquision should disable irq. Possible deadlock scenario pm8xxx_irq_set_type() -> pm8xxx_config_irq() -> spin_lock(&chip->pm_irq_lock) <irq interrupt> -> pm8xxx_irq_handler() -> pm8xxx_irq_master_handler() -> pm8xxx_irq_block_handler() -> pm8xxx_read_block_irq() -> spin_lock(&chip->pm_irq_lock) (deadlock here) This flaw was found using an experimental static analysis tool we are developing for irq-related deadlock.

2023-08-18mfd: wm8998: Update to use maple tree register cacheMark Brown1-1/+1
The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wm8998 driver to use the more modern data structure.
