Subject: [PATCH 4/4] arm64: dts: imx8mq-librem5: Dongwoon DW9714 coil requires higher voltage
Date: Sat, 01 Aug 2026 02:35:23 +0200 [thread overview]
Message-ID: <20260801-pp-pro-camera-v1-4-7b4d90788f9f@ixit.cz> (raw)
In-Reply-To: <20260801-pp-pro-camera-v1-0-7b4d90788f9f@ixit.cz>
From: David Heidelberg <david@ixit.cz>
By datasheet the VDD (in-kernel named vcc) range is between 2.3 to 4.3 V.
Usually it's around 2.8 V. Here it matches the reg_vcam_2v8.
1.8 V here is likely used for i2c level shifter.
Fixes: f00df2bdb512 ("arm64: dts: imx8mq-librem5: describe the voice coil motor for focus control")
