Subject: [PATCH net-next 3/7] net: phy: introduce phy_read_mmd_poll_timeout macro
Date: Fri, 20 Mar 2020 00:39:06 +0800	[thread overview]
Message-ID: <20200319163910.14733-4-zhengdejin5@gmail.com> (raw)
In-Reply-To: <20200319163910.14733-1-zhengdejin5@gmail.com>

it is sometimes necessary to poll a phy register by phy_read_mmd()
function until its value satisfies some condition. introduce
phy_read_mmd_poll_timeout() macros that do this.
