hwmon: Add driver for Texas Instruments TMP464 and TMP468 Add support for Texas Instruments TMP464 and TMP468 temperature sensor ICs. TI's TMP464 is an I2C temperature sensor chip. This chip is similar to TI's TMP421 chip, but with 16bit-wide registers (instead of 8bit-wide registers). The chip has one local sensor and four remote sensors. TMP468 is similar to TMP464 but has one local and eight remote sensors.

hwmon: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

hwmon: Use named initializers for arrays of i2c_device_data While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify indention and usage of commas. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

hwmon: (tmp464) Remove use of i2c_match_id() The function i2c_match_id() is used to fetch the matching ID from the i2c_device_id table. This is often used to then retrieve the matching driver_data. This can be done in one step with the helper i2c_get_match_data(). This helper has a couple other benefits: * It doesn't need the i2c_device_id passed in so we do not need to have that forward declared, allowing us to remove those or move the i2c_device_id table down to its more natural spot with the other module info. * It also checks for device match data, which allows for OF and ACPI based probing. That means we do not have to manually check those first and can remove those checks.
