The Microchip EMC2101 is a SMBus 2.0 fan controller with temperature monitoring. It supports up to 1 fan, 1 internal temperature sensor, 1 external temperature sensor and an 8 entry look up table to create a programmable temperature response. v3: multiple improvements: - rst: drop emc2101-r (same chip, loads config from EEPROM). - dt: fix errors, remove patternProperties and drop emc2101-r. - Switch to regmap-i2c. - Use regmap fields. - Add Power Management support. - Demote dev_info() to dev_dbg(). - Remove "emc2101-r" i2c_device_id. - Remove "microchip,emc2101-r" of_device_id. - Properly implement standby mode. - Use milliseconds instead of millihertz for update_interval. - Drop mutex except for FAN_LUT_DISABLE and TEMP_EXT_CRIT_UNLOCK. - Fix u16 fraction temperature conversions. - Other code cleanups and refactors. v2: multiple improvements: - add emc2101.rst to index.rst. - add missing documentation properties. - Remove FAN_RPM_MIN definition. - Rename FAN_FALSE_READ to FAN_MIN_READ. - pwm_auto_point_temp_hyst_store(): simplify function. - emc2101_fan_min_read(): add missing FAN_MIN_READ condition. - emc2101_fan_min_write(): fix tach_count calculation. - emc2101_init(): fix REG_TACH_MIN value.
