Subject: [PATCH 2/2] iio: adc: max1363: Reorder max11607_mode_list[]
Date: Tue, 29 Apr 2025 12:02:13 -0300 [thread overview]
Message-ID: <20250429150213.2953747-2-festevam@gmail.com> (raw)
In-Reply-To: <20250429150213.2953747-1-festevam@gmail.com>
From: Fabio Estevam <festevam@denx.de>
The IIO core emits warnings when a scan mask is a subset of a previous one
in the available_scan_masks array.
In the current max11607_mode_list[], the s0to3 mode (channels 0–3,
mask 0xF) precedes the s2to3 mode (channels 2–3, mask 0xC). Since 0xC is a
subset of 0xF, the following warning is triggered:
max1363 1-0064: Mask 7 (0xc) is a subset of mask 6 (0xf) and will be ignored
Reordering the max11607_mode_list[] to place s0to3 after s2to3 ensures that
more specific scan modes are listed before broader ones, preventing such
warnings.
This change improves clarity and avoids unnecessary warnings during device
initialization.
