* hwmon: (adt7x10) convert to use maple tree register cacheBo Liu2024-02-251-1/+1
| | | | | | | | | | 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.

* hwmon: (adt7x10) Switch to EXPORT_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron2022-09-251-1/+1
| | | | | | | | | | | These newer PM macros allow the compiler to see what code it can remove if !CONFIG_PM_SLEEP. This allows the removal of messy #ifdef barriers whilst achieving the same result.

* hwmon: (adt7x10) Convert to use regmapGuenter Roeck2022-02-281-17/+71
| | | | | | | | | | | Using regmap lets us use the regmap subsystem for SPI vs. I2C register accesses. It lets us hide access differences in backend code and lets the common code just access registers without knowing their size. We can also use regmap for register caching.

* hwmon: (adt7x10) Make adt7x10_remove() return voidUwe Kleine-König2021-10-121-1/+2
| | | | | | | | | | | | Up to now adt7x10_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.

* hwmon: (adt7410) Add support for the adt7310/adt7320Lars-Peter Clausen2013-04-081-0/+123
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map layout is a bit different, i.e. the register addresses differ between the two variants, but the bit layouts of the individual registers are identical. So both chip variants can easily be supported by the same driver. The issue of non matching register address layouts is solved by a simple look-up table which translates the I2C addresses to the SPI addresses. The patch moves the bulk of the adt7410 driver to a common module that will be shared by the adt7410 and adt7310 drivers. This common module implements the driver logic and uses a set of virtual functions to perform IO access. The adt7410 and adt7310 driver modules provide proper implementations of these IO accessor functions for I2C respective SPI.
