From c23988f84496e937dd255564cb30bec67608dcc6 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Wed, 8 Jul 2026 17:50:04 -0700 Subject: [PATCH] ARM: dts: helios4: add vcc-supply to GPIO expander The pca953x driver requests a 'vcc' supply, producing: pca953x 0-0020: supply vcc not found, using dummy regulator The PCA9655 (PCA9555-compatible) expander is powered by the same always-on 3.3V rail as the other I2C devices on the bus. Add vcc-supply = <®_3p3v> to silence the warning.
