Subject: ARM: dts: i.MX51: Update CPU node
X-Git-Tag: v4.14-rc1~7749^2~39^2~67
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6acde887126dfb1f7fb1ddd5e7523ccaaeca1149;p=platform%2Fkernel%2Flinux-rpi.git

ARM: dts: i.MX51: Update CPU node

This patch updates i.MX51 CPU node:
- Alias for CPU is added to allow using this node in the parent DTS files.
- Removed useless "clock_names" property.
- "clock-latency" value increased to safe using with 32 kHz OSC.
- Defined operating points voltages and "voltage tolerance" properties.
  Values are safe for both commercial and industrial CPU variants.
