From f15bc37d8c336e79491209b268e73868c44733c4 Mon Sep 17 00:00:00 2001 From: Antoniu Miclaus Date: Mon, 8 Sep 2025 07:35:21 +0000 Subject: [PATCH] iio: add IIO_ALTCURRENT channel type Add support for IIO_ALTCURRENT channel type to distinguish AC current measurements from DC current measurements. This follows the same pattern as IIO_VOLTAGE and IIO_ALTVOLTAGE.
