   4 Subject: [PATCH] ARM: dts: bcm2835-rpi-zero-w: Fix bus-width of sdhci
   5
   6 The commit e7774049ff25 ("ARM: dts: bcm283x: Define MMC interfaces at
   7 board level") accidently dropped the bus width for the sdhci on the
   8 RPi Zero W, because the board file was relying on the defaults
   9 from bcm2835-rpi.dtsi. So fix this performance regression by adding
  10 the bus width to the board file.
