2023-04-19hwmon: (ibmpowernv, pwm-fan) Use of_property_present() for testing DT ↵Rob Herring
property presence It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

2023-04-19hwmon: (nzxt-smart2) add another USB IDAleksandr Mezin
This seems to be a new revision of the device. RGB controls have changed, but this driver doesn't touch them anyway. Fan speed control reported to be working with existing userspace (hidraw) software, so I assume it's compatible. Fan channel count is the same. Recently added (0x1e71, 0x2019) seems to be the same device.

2023-04-19hwmon: (gpio-fan) drop of_match_ptr for ID tableKrzysztof Kozlowski
The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). This also fixes !CONFIG_OF error: drivers/hwmon/gpio-fan.c:484:34: error: ‘of_gpio_fan_match’ defined but not used [-Werror=unused-const-variable=] Note(groeck): The build error is only seen if Kconfig dependencies are messed up. The driver depends on OF_GPIO which should depend on OF. This was temporarily broken in linux-next, and it was possible to select CONFIG_OF=n and CONFIG_SENSORS_GPIO_FAN=y. Nevertheless, this is a sensible fix.

2023-04-07hwmon: constify pointers to hwmon_channel_infoKrzysztof Kozlowski

2023-04-03driver core: class: remove struct class_interface * from callbacksGreg Kroah-Hartman
The add_dev and remove_dev callbacks in struct class_interface currently pass in a pointer back to the class_interface structure that is calling them, but none of the callback implementations actually use this pointer as it is pointless (the structure is known, the driver passed it in in the first place if it is really needed again.) So clean this up and just remove the pointer from the callbacks and fix up all callback functions. Cc: Jean Delvare <jdelvare@suse.com> Cc: Guenter Roeck <linux@roeck-us.net> Cc: "David S.

2023-03-12hwmon: (ucd90320) Add minimum delay between bus accessesLars-Peter Clausen
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.

2023-02-03hwmon: (aquacomputer_d5next) Add support for Aquacomputer Aquastream UltimateAleksa Savic
Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer Aquastream Ultimate watercooling pump, which communicates through a proprietary USB HID protocol. Coolant temp and external temp sensor readings are available, along with speed, power, voltage and current of both the pump and optionally connected fan. It also exposes pressure and flow speed readings. Additionally, serial number and firmware version are exposed through debugfs. Tested by a user on Github [1].

2023-02-03hwmon: (aquacomputer_d5next) Add support for Aquacomputer Poweradjust 3Aleksa Savic
Extend aquacomputer_d5next driver to expose the temp sensor of the Aquacomputer Poweradjust 3 fan controller, which communicates through a proprietary USB HID protocol. The Poweradjust 3 is not currently known to expose firmware version and serial number, so don't create debugfs entries if their values can't be retrieved. Tested by a user on Github [1].

2023-02-03hwmon: (it87) Add new chipset IT87952EFrank Crawford
Add IT87952E, a new chip ID (DEV ID 0x8695), which appears to be an updated version of the IT8792E and takes the same configuration. The model name comes from the model name printed on the chip. There is no datasheet publicly available.

2023-02-03hwmon: (it87) Allow multiple chip IDs for force_idFrank Crawford

2023-02-03hwmon: (it87) Allow disabling exiting of configuration modeFrank Crawford
Disabling configuration mode on some chips can result in system hang-ups and access failures to the Super-IO chip at the second SIO address. Never exit configuration mode on these chips to avoid the problem. This patch should be applied in conjunction with a previous one to initialise the second chip for certain mother boards.
