Subject: [PATCH v4 05/14] phy: cadence: Sierra: Make cdns_sierra_phy_init() as phy_ops
Date: Mon, 16 Dec 2019 15:27:03 +0530	[thread overview]
Message-ID: <20191216095712.13266-6-kishon@ti.com> (raw)
In-Reply-To: <20191216095712.13266-1-kishon@ti.com>

Instead of invoking cdns_sierra_phy_init() from probe, add it in
phy_ops so that it's initialized when the PHY consumer invokes
phy_init()
