Subject: ARM: dts: Add new "generic" am4372 device tree file.
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7d83803b493f2ba25fb266f61caf1278ea97e014;p=u-boot.git

ARM: dts: Add new "generic" am4372 device tree file.

With U-boot runtime board detect for DTB selection a "default" dtb needs
to be created. This will be used temporarily until the "proper" dtb is
selected.

Also, add -u-boot.dtsi for AM437x SK and IDK to enable I2C for
board detection via DM_I2C.
