+Subject: [PATCH] thermal: qcom-spmi-adc-tm5: Correct the voltage-code scaling
+ for HC
+
+When support was added for the HC variant, the full_scale_code_volt
+value was copied from the tm5 variant. From the downstream kernel, the
+scaling value is 0x70e4 on PMI632 (tm5 variant), but it is 0x4000 on
+PM660 and PM8998 (HC variant). Correct the ADC code to voltage
+scaling factor for the HC variant.
+
+Fixes: f6c83676c6097 ("thermal/drivers/qcom/spmi-adc-tm5: Add support for HC variant")
+Parent: dt-bindings: mfd: qcom,spmi-pmic: Allow PMIC4 thermal monitor on pm660
