X-Git-Tag: v2025.07-rc1~53^2~8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=132f80803e7ab85f11db5c6a7f5c464504e66a99;p=pandora-u-boot.git

arch: arm: dts: an7581: Add eMMC nodes

Add eMMC nodes with the fixed regulator and fixed clock. It's also
needed to assign the clock and set it to 200MHz as it's set to 150Mhz by
default.
