From d01f63f673e18f3a99ce8d6fbf1a5f58b70990f7 Mon Sep 17 00:00:00 2001 From: Antoniu Miclaus Date: Fri, 7 Aug 2026 11:56:42 +0300 Subject: [PATCH] iio: adc: ade9000: fix overlapping scan_index for current and voltage channels Current channels used scan_index "num" and voltage "num + 1", so with phases 0, 1 and 2 the indices overlapped and no longer matched the IA=0, VA=1, IB=2, VB=3, IC=4, VC=5 layout expected by ade9000_waveform_buffer_config(). Phase B and C buffers were configured incorrectly. Use "num * 2" for current and "num * 2 + 1" for voltage to get the non-overlapping 0/1, 2/3, 4/5 layout.
