From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lee Jones Subject: [PATCH v6 04/10] ARM: STi: STiH407: Provide generic (safe) DVFS configuration Date: Wed, 9 Dec 2015 15:58:11 +0000 Message-ID: <1449676697-25432-5-git-send-email-lee.jones@linaro.org> References: <1449676697-25432-1-git-send-email-lee.jones@linaro.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1449676697-25432-1-git-send-email-lee.jones@linaro.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Cc: devicetree@vger.kernel.org, kernel@stlinux.com, linux-pm@vger.kernel.org, viresh.kumar@linaro.org, rjw@rjwysocki.net, Lee Jones , ajitpal.singh@st.com, maxime.coquelin@st.com 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.
