[PATCH 4/4] arm64: dts: imx8mq-librem5: Dongwoon DW9714 coil requires higher voltage

From: David Heidelberg via B4 Relay

Date: Fri Jul 31 2026 - 20:40:16 EST


From: David Heidelberg <david@xxxxxxx>

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.
