Subject: [PATCH] arm64: dts: mt8183: add cbas node under cros_ec

Add a 'cbas' device node for supporting table mode switch in
kukui devices.

Kukui platforms with detacheable base have an additional input
device under cros-ec, which reports SW_TABLET_MODE regarding
its base state (e.g. base flipped or detached).

I'm not able to find any binding description for this. It seems linux-next has
driver binding to this compatible, but the description is missing.

Can you please clarify.

Thanks,

Yep, that's correct.
Let me resend this with v2 after the dt-binding patch is applied.

In this series, I requested queueing these to hid tree:

[v5, 1/2] mfd: google,cros-ec: add DT bindings for a baseboard's switch device
https://patchwork.kernel.org/project/linux-input/patch/[email protected]/

[v5, 2/2] HID: google: Add of_match table to Whiskers switch device.
https://patchwork.kernel.org/project/linux-input/patch/[email protected]/

Later I found that I missed a comment from [v5, 1/2]
But only [v5, 2/2] part is already applied to hid tree as I asked for it.

I sent a v6 dt-binding patch is here (not yet applied)
https://patchwork.kernel.org/project/linux-input/patch/[email protected]/

sure, let me upload v7 with dt-bindings + mt8183.dtsi together.

Oops.. :-S
(Why did I think this should go through hid?)
Thanks a lot for pointing out the basic but critical mistake.

This should be just cbas, remove base_detection. It was a bit confusing follow
these series. If [v5, 2/2] is already applied in hid tree, I'd suggest send a v7
version including:

[v7, 1/2] mfd: google,cros-ec: add DT bindings for a baseboard's switch device
[v7, 2/2] arm64: dts: mt8183: add cbas node under cros_ec

Both patches can go through the Matthias tree, but the first one also needs an
Ack from Lee Jones, MFD maintainer, which I think is not cc'ied, so unlikely to
give you the needed ack.

Thanks,
Enric
