Subject: ARM: i.MX6 Phytec PFLA02: Add supplies for the SoC internal regulators
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=942526c35e97b7758b4a07ba456870f4ca15c1c6;p=linux-beck.git

ARM: i.MX6 Phytec PFLA02: Add supplies for the SoC internal regulators

The SoC internal regulators for the CPU and the SoC come from the
DA9063 vdd_core and vdd_soc. Add this relationship to the device tree
so that the voltage drop on the SoC internal LDO regulators can be
minimized.
