Subject: am33xx/am43xx: Add platform data for GPIOs
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=90345c92a82c92203fcf5d00678d15c95f31a379;p=project%2Fbcm63xx%2Fu-boot.git

am33xx/am43xx: Add platform data for GPIOs

On these platforms we have many cases of boards that enable device model
and GPIO support but do not enable OF_CONTROL and pass in a device tree
with the binary.  We need to bring in the platform data here as well.

Tested on Beaglebone Black.
