[PATCH v2 0/2] AM57x EVM Device Tree Overlays

[PATCH v2 0/2] AM57x EVM Device Tree Overlays

[Andrew Davis]

Hello all,

These is an uncontroversial (hopefully) DT Overlay to support the
TI AM57x EVM. More complex cases are staged and ready to follow but
wanted to test the water with this one.

For some reason dtbs_check does not get run on overlays, this
will need further investigation to fix in kbuild. For now I ran
it through manually but am not 100% sure it actually checked it,
so double checks here very welcome.

Series depends on https://www.spinics.net/lists/kernel/msg4548509.html

Thanks,
Andrew

Changes from v1:
 - Made touchscreen node name generic
 - Used proper interrupt flags

[PATCH v2 1/2] ARM: dts: ti: Add AM57xx GP EVM board support

[Andrew Davis]

The AM57xx GP EVM boards are built on top the AM57xx BeagleBoard-X15.
The EVM extends the BeagleBoard by adding a touchscreen, some buttons,
and a handful of peripheral extension slots.

Being a plugin extension of an existing standalone board; we define
the am57xx-evm as a composite-DTB of the base am57xx-beagle-x15
and a new am57xx-evm overlay.

[PATCH v2 2/2] ARM: dts: ti: Add AM57xx GP EVM Rev A3 board support

[Andrew Davis]

The A3 revision of the AM57xx GP EVM has the same EVM feature set as the
original but is paired with an updated revision C BeagleBoard X15.

DT Overlays allow us to model this in the same way, we simply apply the
EVM overlay to the Rev C BeagleBoard to create the Rev A3 AM57xx GP EVM.

Looks like we now have commit 26c9134a370a ("Merge branch 'dt/dtbo-rename'
into dt/next") in Linux next.

Can these two patches now be applied if I merge in the commit above?

Regards,

Tony

26c9134a370a is the same (v2) as the series (v1) I pointed to in the
commit message. This series works on top of either.

Thanks,
Andrew

Rob, are those commits immutable and OK to use as a base?
