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

+****************************
+Technexion i.MX7D Pico board
+****************************
+
+This file documents the Buildroot support for the Technexion i.MX7D Pico board.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX7D Pico board:
+
+ make imx7dpico_defconfig
+
+Build all components:
+
+ make
+
+You will find in output/images/ the following files:
+ - imx7d-pico.dtb
+ - rootfs.ext4
+ - rootfs.tar
+ - sdcard.img
+ - u-boot.imx
+ - zImage
+
+Flash the eMMC
+==============
+
+In the U-Boot prompt lauch:
+
+=> ums 0 mmc 0
+
+This will mount the eMMC content in the host PC as a mass storage device.
+
+To determine the device associated to the eMMC card have a look in the
+/proc/partitions file:
+
+ cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on the eMMC card. Launch the following
+command as root:
+
+ dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the eMMC content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/common/imx/genimage.cfg.template.
+
+Boot the i.MX7D Pico board
+==========================
+
+To boot your newly created system:
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
