Forgot changelog
V1 -> V2

 - keep original out-of-tree AD7173 naming
 - remove gpio_cleanup
 - handle 32bit realbits offset case
 - use iio_device_claim_direct_mode, drop own mutex
 - use dev_err_probe
 - cleanup headers include
 - use GENMASK() and FIELD_PREP()
 - use HZ_PER_MHZ
 - change #ifdef GPIOLIB to if( IS_ENABLED(CONFIG_GPIOLIB)) 
 - use gpio-regmap
 - change boolean flag in info struct to number of gpios
 - NIH memset64
 - use struct pointers for config comparison
 - use spi_write_then_read for ADC reset
 - use stack allocated buffer for reset
 - define constant for reset sequence size
 - use kcalloc instead of kzalloc
 - change of naming to fw of dt parse function
 - change de-referencing chain to local variable dev in multiple locations
 - drop write_raw_get_fmt
 - add driver private data to spi_device_id table
 - use fsleep() instead of usleep_range()
 - put config value inline
 - align read/write raw arguments
 - remove zeroed values from channel templates structure
 - define constants for temperature sensor positive and negative inputs
 - always enable temperature channel
 - configure spi clock phase and polarity from driver

 misc changes (test bit, return disable all, indentation fix, change statements to single line)
