Subject: [PATCH v3 2/3] hwmon/ltc2990: Generalise DT to fwnode support
Date: Thu, 15 Aug 2019 14:58:01 +0200
Message-ID: <20190815125802.16500-2-max@enpas.org> (raw)
In-Reply-To: <20190815125802.16500-1-max@enpas.org>

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.
