Subject: [PATCH 05/12] OMAP TWL/TPS OPP: vsel rounding belongs in opp_twl_tps.c
Date: Thu, 17 Dec 2009 17:47:36 -0700 [thread overview]
Message-ID: <20091218004735.7694.13673.stgit@localhost.localdomain> (raw)
In-Reply-To: <20091218004617.7694.84525.stgit@localhost.localdomain>
The vsel roundoff code belongs in omap_twl_uv_to_vsel(), not
omap_opp_populate(), since other code may use omap_twl_uv_to_vsel().
