Subject: mmc: bcm283x: Add support for bcm2711 device in bcm2835_sdhci
X-Git-Tag: v2019.10-rc4~19^2~2
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;ds=sidebyside;h=e0e3c7dadac4fa45f91c31299045cb7ada94f495;p=oweals%2Fu-boot.git

mmc: bcm283x: Add support for bcm2711 device in bcm2835_sdhci

The bcm2711 has two emmc controllers. The difference is the clocks
they use. Add support for the second emmc controller.
