Subject: ARM64: zynqmp: Add no-1-8-v property to SD node.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=323f7497cc903af4685d6c16231a689f1e22ba78;p=thirdparty%2Fu-boot.git

ARM64: zynqmp: Add no-1-8-v property to SD node.

There is no support to switch to 1.8V and use
UHS mode on 1.0 silicon. Hence, this patch add
no-1-8-v property to SD node to denotes 1.8v card
voltage is not supported on this system, even if
the controller claims it is.
