Subject: [Regression?] Removed regulator support in ehci-omap
Date: Mon, 11 Apr 2011 13:32:14 +0400	[thread overview]
Message-ID: <20110411093214.GA18215@rainbow> (raw)

Hi, guys!

Can anyone explain why regulator support has been removed from ehci-omap
driver in commit 19403165 ("usb: host: omap: ehci and ohci simplification")[1]?
In 2.6.37/2.6.38 it was enough to apply simple patch[2] adding regulators
description to board file to make USB work on omap3evm board (because USB PHY
is powered via regulator). But now it won't work anymore in 2.6.39-rc2.
BTW, I suspect that this commit also broke USB on omap3pandora board, as it
defines "hsusb0" regulator supply in its board file:

[mad@madhouse linux-2.6]$ git grep hsusb arch/arm/mach-omap2/board*
arch/arm/mach-omap2/board-omap3pandora.c:       REGULATOR_SUPPLY("hsusb0", "ehci

I can't find any clues in commit message on why regulators support was removed
and what should be used instead if this removal was intentional, so I'm a bit
puzzled about what to do now. Any help will be appreciated.
