If anyone has any objections, please let me know. ------------------ From: Hans de Goede [ Upstream commit 64e0d839c589f4f2ecd2e3e5bdb5cee6ba6bade9 ] Testing has shown that reading multiple registers at once (for 10-bit ADC values) does not work. Set the use_single_read regmap_config flag to make regmap split these for us. This should fix temperature opregion accesses done by drivers/acpi/pmic/intel_pmic_chtdc_ti.c and is also necessary for the upcoming drivers for the ADC and battery MFD cells.
