Subject: [RFC PATCH net-next 16/22] net: dsa: mt7530: move lowering port 5 RGMII driving to mt7530_setup()
Date: Fri, 21 Apr 2023 17:36:42 +0300 [thread overview]
Message-ID: <20230421143648.87889-17-arinc.unal@arinc9.com> (raw)
In-Reply-To: <20230421143648.87889-1-arinc.unal@arinc9.com>
From: Arınç ÜNAL <arinc.unal@arinc9.com>
Move lowering Tx driving of rgmii on port 5 to right before lowering of Tx
driving of trgmii on port 6 on mt7530_setup().
This way, the switch should consume less power regardless of port 5 being
used.
