* hwmon: (ltc2992) Set `can_sleep` flag for GPIO chipLars-Peter Clausen2023-03-151-0/+1
| | | | | | | | | | | | | | The ltc2992 drivers uses a mutex and I2C bus access in its GPIO chip `set` and `get` implementation. This means these functions can sleep and the GPIO chip should set the `can_sleep` property to true. This will ensure that a warning is printed when trying to set or get the GPIO value from a context that potentially can't sleep. Fixes: 9ca26df1ba25 ("hwmon: (ltc2992) Add support for GPIOs.")

* hwmon: tmp512: drop of_match_ptr for ID tableKrzysztof Kozlowski2023-03-121-1/+1
| | | | | | | | | | | | | | The driver will match mostly by DT table (even thought there is regular ID table) so there is little benefit in of_match_ptr (this also allows ACPI matching via PRP0001, even though it might not be relevant here). This also fixes !CONFIG_OF error: drivers/hwmon/tmp513.c:610:34: error: ‘tmp51x_of_match’ defined but not used [-Werror=unused-const-variable=] Fixes: 59dfa75e5d82 ("hwmon: Add driver for Texas Instruments TMP512/513 sensor chips.")

* hwmon: (ucd90320) Add minimum delay between bus accessesLars-Peter Clausen2023-03-121-0/+75
| | | | | | | | | | | | | | | | | | | | When probing the ucd90320 access to some of the registers randomly fails. Sometimes it NACKs a transfer, sometimes it returns just random data and the PEC check fails. Experimentation shows that this seems to be triggered by a register access directly back to back with a previous register write. Experimentation also shows that inserting a small delay after register writes makes the issue go away. Use a similar solution to what the max15301 driver does to solve the same problem. Create a custom set of bus read and write functions that make sure that the delay is added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On various Gigabyte AM4 boards (AB350, AX370), the second Super-IO chip (IT8792E) needs to be in configuration mode before accessing the first due to a bug in IT8792E which otherwise results in LPC bus access errors. This needs to be done before accessing the first Super-IO chip since the second chip may have been accessed prior to loading this driver. The problem is also reported to affect IT8795E, which is used on X299 boards and has the same chip ID as IT8792E (0x8733). It also appears to affect systems with IT8790E, which is used on some Z97X-Gaming boards as well as Z87X-OC, and other more recent Gigabyte boards.

| * | hwmon: (coretemp) Simplify platform device handlingRobin Murphy2023-02-031-70/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Coretemp's platform driver is unconventional. All the real work is done globally by the initcall and CPU hotplug notifiers, while the "driver" effectively just wraps an allocation and the registration of the hwmon interface in a long-winded round-trip through the driver core. The whole logic of dynamically creating and destroying platform devices to bring the interfaces up and down is error prone, since it assumes platform_device_add() will synchronously bind the driver and set drvdata before it returns, thus results in a NULL dereference if drivers_autoprobe is turned off for the platform bus. Furthermore, the unusual approach of doing that from within a CPU hotplug notifier, already commented in the code that it deadlocks suspend, also causes lockdep issues for other drivers or subsystems which may want to legitimately register a CPU hotplug notifier from a platform bus notifier. All of these issues can be solved by ripping this unusual behaviour out completely, simply tying the platform devices to the lifetime of the module itself, and directly managing the hwmon interfaces from the hotplug notifiers. There is a slight user-visible change in that /sys/bus/platform/drivers/coretemp will no longer appear, and /sys/devices/platform/coretemp.n will remain present if package n is hotplugged off, but hwmon users should really only be looking for the presence of the hwmon interfaces, whose behaviour remains unchanged.
