| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename the SPMI device helper which is used to lookup a device from its OF node as spmi_find_device_by_of_node() so that it reflects the implementation and matches how other helpers like this are named. This will specifically make it more clear that this is a lookup function which returns a reference counted structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mfd: qcom-spmi-pmic: Fix revid implementationJohan Hovold2023-11-011-16/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

We expect project_name to be NUL-terminated based on its use with pr_info: | pr_info("PRCMU firmware: %s(%d), version %d.%d.%d\n", | fw_info.version.project_name, | fw_info.version.project, | fw_info.version.api_version, | fw_info.version.func_version, | fw_info.version.errata); Moreover, NUL-padding does not seem to be needed. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Let's also change `PRCMU_FW_PROJECT_NAME_LEN` to just sizeof(fw_info.version.project_name) as this is more idiomatic strscpy usage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct iqs62x_fw_blk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 wcd934x to use the more modern data structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we allow the AXP15060 and the AXP806 PMICs to omit the interrupt line to the SoC, and we skip registering the PEK (power key) driver in this case, since that crashes when no IRQ is described in the DT node. The IRQ pin potentially not being connected to anything does affect more PMICs, though, and the PEK driver is not the only one requiring an interrupt: at least the AC power supply driver crashes in a similar fashion. Generalise the handling of AXP MFD devices when the platform tables describe no interrupt, by allowing each device to specify an alternative MFD list for this case. If no specific alternative is specified, we go with the safe default of "just the regulators", which matches the current situation. This enables new devices using the AXP313a PMIC, but not connecting the IRQ pin.

For these, the only registered restart handler is the warm reboot via tegra's PMC. As the bootloader of the tegra20 requires the VDE, it must be ensured that VDE is enabled (which is the case after a cold reboot). For the "normal reboot", this is basically the case since 8f0c714ad9be. However, this workaround is not executed in case of an emergency restart. In case of an emergency restart, the system now simply hangs in the bootloader, as VDE is not enabled (because it is not used). The TPS658629-Q1 provides a SOFT RST bit in the SUPPLYENE reg to request a (cold) reboot, which takes at least 20ms (as the data sheet states). This avoids the hang-up. Tested on a TPS658640.
