[PATCH v3 6/7] ARM: dts: bcm283x: switch from &sdhci to &sdhost Gerd Hoffmann <kraxel@redhat.com> - 2017-02-21 10:10 +0100

sdcard access with the sdhost controller is faster.
Read access (dd with 64k blocks on rpi2):
CONFIG_MMC_SDHCI_IPROC: 11-12 MB/s
CONFIG_MMC_BCM2835: 19-20 MB/s
Differences on write access are pretty much in the noise.
