Subject: [PATCH 0/4] Dongwoon DW9714 - correct vcc/vdd supply voltage
Date: Sat, 01 Aug 2026 02:35:19 +0200 [thread overview]
Message-ID: <20260801-pp-pro-camera-v1-0-7b4d90788f9f@ixit.cz> (raw)
So much mess, as people defines 1.8V i2c level shifters instead of VDD.
I don't pocess any of these devices, so please test carefully,
you may need to in addition to this change put regulator-always-on to
the 1.8V which was previously abused instead of VDD. Careful about
combination when camera which pulls in 1.8V (usually iovdd) as a byproduct
takes care of i2c supply for the coil.
