Date: Fri, 2 May 2014 14:07:32 -0700 From: Soren Brinkmann <soren.brinkmann@...inx.com> To: Rob Herring <robh+dt@...nel.org>, Pawel Moll <pawel.moll@....com>, Mark Rutland <mark.rutland@....com>, Ian Campbell <ijc+devicetree@...lion.org.uk>, Kumar Gala <galak@...eaurora.org>, Russell King <linux@....linux.org.uk>, Michal Simek <michal.simek@...inx.com> Cc: devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, git@...inx.com, Soren Brinkmann <soren.brinkmann@...inx.com> Subject: [PATCH] ARM: zynq: dt: Add a fixed regulator for CPU voltage To silence the warning cpufreq_cpu0: failed to get cpu0 regulator: -19 from the cpufreq driver regarding a missing regulator, add a fixed regulator to the DT. Zynq does not support voltage scaling and the CPU rail should always be supplied with 1 V, hence it is added in the SOC-level dtsi.
