Paul, Would you please take this bugfix for 3.7-rc2? The suggestion to mail you came from Toni Lindgren. The context where it came from is here: http://lists.arm.linux.org.uk/lurker/message/20121015.191630.bdae3c50.en.html Thanks, Richard ----- Forwarded message from Richard Cochran [off-list ref] ----- Date: Mon, 15 Oct 2012 21:16:32 +0200 From: Richard Cochran <richardcochran@gmail.com> To: netdev at vger.kernel.org Cc: linux-arm-kernel at lists.infradead.org, Arnd Bergmann <arnd@arndb.de>, David Miller [off-list ref], Russell King [off-list ref], Mugunthan V N [off-list ref] 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 <redacted> 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.
