hwmon/ltc2990: Generalise DT to fwnode support (06a1c69c) · Commits · 戴 / test

ltc2990 will now use device_property_read_u32_array() instead of of_property_read_u32_array() - allowing the use of software nodes via fwnode_create_software_node(). This allows code using i2c_new_device() to specify a default measurement mode for the LTC2990 via fwnode_create_software_node(). Signed-off-by:
