Subject: [PATCH net-next v5 2/5] net: phy: Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy
Date: Thu,  2 Feb 2023 11:00:34 +0800	[thread overview]
Message-ID: <20230202030037.9075-3-Frank.Sae@motor-comm.com> (raw)
In-Reply-To: <20230202030037.9075-1-Frank.Sae@motor-comm.com>

 Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy.
 This is a preparatory patch. Add BIT macro for 0xA012 reg, and
 supplement for 0xA001 and 0xA003 reg. These will be used to support dts.
