# \[PATCH 1/6\] i2c: bcm-kona: register with subsys\_initcall - From: Matt Porter \ - Date: 2014-02-04 12:21:06 - List: linux-devicetree - Page: https://ratatoskr.run/linux-devicetree/2014/02/4191691 - Thread: https://ratatoskr.run/linux-devicetree/2014/02/4191685/t.md ```text Voltage regulators are needed very early due to deferred probe being incompatible with built-in USB gadget drivers. In order to have the PMU driver available before USB UDC, make i2c available during subsys_initcall.
