2022-05-22hwmon: (nct6775) Add i2c driverZev Weiss
This driver provides an i2c I/O mechanism for the core nct6775 driver, as might be used by a BMC. Because the Super I/O chip is shared with the host CPU in such a scenario (and the host should ultimately be in control of it), the i2c driver is strictly read-only to avoid interfering with any usage by the host (aside from the bank-select register, which seems to be replicated for the i2c interface).

Boards such as * PRO H410T * PRIME H410M-R * ROG STRIX X570-E GAMING WIFI II have got a nct6775 chip, but by default there's no use of it because of resource conflict with WMI method. This commit adds such boards to the WMI monitoring list.

2022-05-22hwmon: (lm83) Remove unused include directivesKarl Mehltretter
Some include directives are no longer necessary due to previous driver changes. Remove them now to further improve driver code clarity. Mutex usage has ceased since commit 719af4f1a40b ("hwmon: (lm83) Use regmap"). Ever since commit a0ac840d99fa ("hwmon: (lm83) Convert to use devm_hwmon_device_register_with_groups") functions sysfs_create_group and sysfs_remove_group are no longer used by the driver.

2022-05-22hwmon: (pmbus) Register with thermal for PSC_TEMPERATUREEduardo Valentin
Some pmbus device drivers have device tree support and may want to use of-thermal to register a thermal zone OF sensor for those device drivers. This way we allow describing device tree thermal zones for pmbus device drivers with device tree support. This patch achieves this by registering pmbus sensors with thermal subsystem if they are PSC_TEMPERATURE and are providing _input hwmon interface.

2022-05-22hwmon: (adt7475) Add support for pin configurationChris Packham
The adt7473, adt7475, adt7476 and adt7490 have pins that can be used for different functions. On the adt7473 and adt7475 this is pins 5 and 9. On the adt7476 and adt7490 this is pins 10 and 14. The first pin can either be PWM2(default) or SMBALERT#. The second pin can be TACH4(default), THERM#, SMBALERT# or GPIO. The adt7475 driver has always been able to detect the configuration if it had been done by an earlier boot stage. Add support for configuring the pins based on the hardware description in the device tree.

2022-05-21i2c: ismt: Provide a DMA buffer for Interrupt Cause LoggingMika Westerberg
Before sending a MSI the hardware writes information pertinent to the interrupt cause to a memory location pointed by SMTICL register. This memory holds three double words where the least significant bit tells whether the interrupt cause of master/target/error is valid. The driver does not use this but we need to set it up because otherwise it will perform DMA write to the default address (0) and this will cause an IOMMU fault such as below: DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set To prevent this from happening, provide a proper DMA buffer for this that then gets mapped by the IOMMU accordingly.

2022-05-20clk: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller)Gabriel Fernandez
This driver manages Reset and Clock of STM32MP13 soc. It uses a clk-stm32-core module to manage stm32 gate, mux and divider for STM32MP13 and for new future soc. All gates, muxes, dividers are identify by an index and information are stored in array (register address, shift, with, flags...) This is useful when we have two clocks with the same gate or when one mux manages two output clocks.

2022-05-20clk: ti: clkctrl: replace usage of found with dedicated list iterator variableJakob Koschel
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

2022-05-20clk: ti: composite: Prefer kcalloc over open coded arithmeticLen Baker
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.

2022-05-20wwan: iosm: use a flexible array rather than allocate short objectsJakub Kicinski
GCC array-bounds warns that ipc_coredump_get_list() under-allocates the size of struct iosm_cd_table *cd_table. This is avoidable - we just need a flexible array. Nothing calls sizeof() on struct iosm_cd_list or anything that contains it.
