[PATCH 4/4] at91sam9263ek: enable DT support
Sam Ravnborg
sam at ravnborg.org
Mon Jan 1 05:15:23 PST 2018
Add at91sam9263ek.dts to build.
Include mmc1 in at91sam9263ek.dts, as mmc1 is what the evaluation
kit uses for the SD card.
Add DT specific of_init
Adjust build to drop non-DT files from mach-at91
