Subject: [PATCH 16/36] mtd: onenand: omap: Remove regulator management code
Date: Wed, 11 Jun 2014 11:56:21 +0300 [thread overview]
Message-ID: <1402477001-31132-17-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1402477001-31132-1-git-send-email-rogerq@ti.com>
None of the OMAP platforms are suppying the "regulator_can_sleep"
parameter via platform data. Regulator management is generic
enough to be done in onenand_base driver if required.
Mark the "regulator_can_sleep" platform data parameter as deprecated.
