X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=88c5ed4aa00d222f353ae7b0efd2554a8f060a70;p=pandora-u-boot.git

arm: dts: Add i.MX943 EVK board dtsi files

Introduce the base dtsi files for the i.MX943 EVK board. These files
define the essential components such as messaging units, uSDHC, GPIOs
and lpuart for board bring-up.
