   4 Subject: [PATCH] ARM: dts: imx7d-pico: Pass 'no-1-8-v' property to the eMMC
   5
   6 Currently the following eMMC error is seen:
   7
   8 mmc1: mmc_select_hs200 failed, error -74
   9
  10 On imx7d-pico the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v'
  11 property to properly describe that 1.8V operation is not possible.
