Subject: [PATCH v4 1/4] net: phy: dp83867: Add documentation for optional impedance control
Date: Tue, 18 Oct 2016 16:50:17 +0530 [thread overview]
Message-ID: <20161018112020.30273-2-mugunthanvnm@ti.com> (raw)
In-Reply-To: <20161018112020.30273-1-mugunthanvnm@ti.com>
Add documention of ti,min-output-impedance and ti,max-output-impedance
which can be used to correct MAC impedance mismatch using phy extended
registers.
