From: Kalle Jokiniemi To: linux-omap@vger.kernel.org Cc: Kalle Jokiniemi Subject: [PATCH 2/3] ARM: OMAP: SmartReflex driver: added required register and bit definitions. Date: Fri, 6 Jun 2008 12:49:48 +0300 Added new register and bit definitions to enable Smartreflex driver integration. Also PRM_VC_SMPS_SA bit definitions' naming was changed to match the naming of other similar bit definitions.
