   4 Subject: [PATCH] ARM: dts: qcom: ipq8064: disable mmc-ddr-1_8v for sdcc1
   5
   6 It was reported non working mmc with this option enabled.
   7 Both mmc for ipq8064 are supplied by a fixed 3.3v regulator so mmc can't
   8 be run at 1.8v.
   9 Disable it to restore correct functionality of this SoC feature.
