From 243eccb2aa7d22c176891a9caee81f62d1637212 Mon Sep 17 00:00:00 2001 From: Jishnu Prakash Date: Tue, 2 Mar 2021 09:26:31 +0530 Subject: [PATCH] iio: qcom-spmi-adc5: update scaling ratios for SMB_ICHG and SMB_IIN Update scaling ratios for SMB_ICHG and SMB_IIN ADC channels, following HW recommendation. Update default prescaling values used for SMB_IIN and ICHG_FB channels to match changes made in the prescaling array.
