Subject: [PATCHv6 08/14] ARM: OMAP3+: vp: use new vp_params for calculating vddmin and vddmax
Date: Thu, 31 May 2012 16:55:44 +0300 [thread overview]
Message-ID: <1338472550-20743-9-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1338472550-20743-1-git-send-email-t-kristo@ti.com>
Now we select the vddmin and vddmax values based on both pmic and
voltage processor data, this allows usage of different power ICs.
