Subject: [PATCH 2/5] ARM: OMAP3+: hwmod: Add AM33XX HWMOD data for davinci_mdio
X-Mailer: git-send-email 1.7.2.5

From: Mugunthan V N <mugunthanvnm@ti.com>

This patch adds minimal hwmod support for davinci mdio driver. This patch
requires rework on parent child relation between cpsw and davinci mdio
hwmod data to support runtime PM.
