Hi,

this series adds initial support for the TQMLS1043A, TQMLS1046A and
TQMLS1088A SoM on the MBLS10xxA baseboard. These three modules share a
common layout and a common baseboard.

Patch 1 removes an non-existing spi controller
Patch 2 and 4 add the the compatible to dt bindings
Patch 3 and 5 add the .dts[i] files for SoMs and baseboard
Patch 6 updates MAINTAINERS

Changes in v2:
* Added Acked-Bys from Conor Dooley
* Renamed gpio nodes
* Removed trailing empty line

Best regards
Gregor

I do not have a branch for this file, so you may want to send the
change to Arnd directly.

The MAINTAINERS files can usually go into the same branch
as arch/arm/mach-*/ and arch/arm64/Kconfig changes. If you have
nothing for that, merging this one along with the corresponding
arch/arm64/boot/dts changes is also fine.

We used to have a separate branch just for the maintainer
file updates a long time ago, but they rarely cause conflicts.

Whichever way you end up doing it, please ensure that the person
sending the pull request or patch addresses it to:soc@kernel.org
cc:linux-arm-kernel@lists.infradead.org to make it end up in
patchwork, otherwise I'm more likely to miss it or expect that
I'll get it as part of the normal pull requests.

Plus, there is no really reason to split such trivial maintainer change
into separate commit.
