From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lee Jones Subject: [PATCH v2 1/9] ARM: STi: STiH407: Provide generic (safe) DVFS configuration Date: Wed, 24 Jun 2015 14:59:00 +0100 Message-ID: <1435154348-28840-2-git-send-email-lee.jones@linaro.org> References: <1435154348-28840-1-git-send-email-lee.jones@linaro.org> Return-path: In-Reply-To: <1435154348-28840-1-git-send-email-lee.jones@linaro.org> Sender: linux-kernel-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Cc: kernel@stlinux.com, rjw@rjwysocki.net, viresh.kumar@linaro.org, linux-pm@vger.kernel.org, devicetree@vger.kernel.org, ajitpal.singh@st.com, Lee Jones List-Id: devicetree@vger.kernel.org You'll notice that the voltage cell is populated with 0's. Voltage information is very platform specific, even depends on 'cut' and 'substrate' versions. Thus it is left blank for a generic (safe) implementation. If other nodes/properties are provided by the bootloader, the ST CPUFreq driver will over-ride these generic values.
