Subject: [PATCH v6 4/5] ab8500: power: export abx500_res_to_temp tables for hwmon
This patch exports the thermistor resistance-to-temperature tables, so that the
hwmon driver can access them, and also adds the corresponding table size
variables.
Signed-off-by: Hongbo Zhang <hongbo.zhang@...aro.org>
