v2 cover AM57x EVM Device Tree Overlays

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

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

In reply to 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.

Hi Andrew & Rob,

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.

Quoted 6 lines

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

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,

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