Subject: [PATCH 2/2] ARM: dts: imx6qdl: phycore-som: Add custom volt/freq table
The PHYTEC phyCORE-i.MX6QDL SOM-modules are operating with a slightly
different voltage and frequency values in contrast to the generic
i.MX6Q/DL tables. The values have been adjusted to achieve the most
stable condition for the PHYTEC-modules. Introduce imx6q- and
imx6dl-phycore dtsi files with the modified power tables.
