Subject: [PATCH 2/9] ARM: boards: protonic-rk356x: Remove VIN measurement
Date: Wed, 4 Mar 2026 12:00:06 +0100 [thread overview]
Message-ID: <20260304110013.495725-3-robin.van.der.gracht@protonic.nl> (raw)
In-Reply-To: <20260304110013.495725-1-robin.van.der.gracht@protonic.nl>
The VIN measurement is inaccurate and requires storing channel and
multiplier information in the board code. This becomes cumbersome
when more boards are added.
