Sure, please submit it for inclusion. Who is the maintainer for arch/arm64/boot/dts/freescale/ ? Can they pick up all the freescale related dts changes and submit them as a pull request? Should they go through Shawn's tree maybe? Arnd

Thanks Arnd. For now, may-be I can send this patchset with Rob's Acked-by added for 1/2 to 'arm@kernel.org'. So that this can be picked by via the arm-soc tree. Shawn, I hope it's ok with you. In the meanwhile, I will discuss internally as to how we can have in place a freescale maintainer, who can submit the pull requests to the 'arm-soc' tree. Regards, Bhupesh

I'm maintaining a git tree, collecting all Freescale arm32 platform patches, and sending them to arm-soc for each merge window. If I can be copied on those arm64 patches, I do not mind handling them together with arm32 ones. Shawn

Thanks Shawn. Sure, I will make sure to remember the same for future arm64 patches. Regards, Bhupesh

Shawn, Thanks a lot for offering to help. Sorry for a very delayed response as I was on vacation. I have recently been made responsible by the company to push and track the upstreaming of all armv8 related software within the Digital Networking group of FSL/NXP which is currently the only business unit to use ARMv8 cores. We also agreed in an internal discussion that it will be good for me to also help organize patches for upstream acceptance. I think I can help to make it more effective in communicating community requirements and feedback to all related developers and their management. And I can also help to enable the internal test team to better test the staging patches before they hit the mainline. Regards, Leo

This patch updates the LS2080a DTSI (DTS Include) file to add support for eight SP805 Watchdog units which can be used to reset the eight Cortex-A57 cores available on LS2080A.
