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.
