From c60d699be1eb26a14157cfa5b1ac0cf8afce0dcb Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Mon, 23 Sep 2019 19:41:33 +0200 Subject: [PATCH] ARM: dts: bcm2835-rpi-zero-w: Fix bus-width of sdhci The commit e7774049ff25 ("ARM: dts: bcm283x: Define MMC interfaces at board level") accidently dropped the bus width for the sdhci on the RPi Zero W, because the board file was relying on the defaults from bcm2835-rpi.dtsi. So fix this performance regression by adding the bus width to the board file.
