Subject: [PATCH 1/2] include: mdio: Add private field to mdio structure
Date: Wed, 31 Jul 2019 15:06:18 +0530	[thread overview]
Message-ID: <1564565779-29537-2-git-send-email-harini.katakam@xilinx.com> (raw)
In-Reply-To: <1564565779-29537-1-git-send-email-harini.katakam@xilinx.com>

Add a priv pointer to mdio structure to be used by mdio devices if
required.

This priv field will be used by gmii2rgmii driver. As this IP has
no capability to read status on the MDIO bus, the driver currently
snoops the same and needs the instance information is some private
field. Since phy device "priv" can be used by external phy drivers,
it is not appropriate. Hence this addition to mdio device. This is
a temporary solution before the IP can be improved. The need for
this priv field can be re-evaluated later based on other mdio devices.
