Subject: [PATCH 02/13] phy: cadence: Sierra: Make "phy_clk" and "sierra_apb" optional resources
Date: Wed, 16 Oct 2019 17:01:06 +0530 [thread overview]
Message-ID: <20191016113117.12370-3-kishon@ti.com> (raw)
In-Reply-To: <20191016113117.12370-1-kishon@ti.com>
Certain platforms like TI J721E using Cadence Sierra Serdes
doesn't provide explicit phy_clk and reset (APB reset) control.
Make them optional here.
