Subject: [PATCH linux-next v1 0/3]  spacemit: k1-bananapi-f3: Fix the power source of USB3 nodes
Date: Wed, 25 Mar 2026 13:46:07 +0530	[thread overview]
Message-ID: <20260325081700.1502-1-linux.amoon@gmail.com> (raw)

Following changes fix the power source of USB 3 on K1-Bananapi-F3
development board.

Bananapi F3 schematics.
