It seems that we can simply remove the check since 'adc' can never
be an invalid address here.

I revisit some code of subdevs and you are right.
Squash your patch into my driver patch and add your Tested-by in

1) This is based on much too new a release
2) the fact that it's based on this new a release makes me suspect it hasn't
been sitting in linux-next either, at least not since before -rc7.
Conclusion: Please resend post merge window and we'll queue it up for the
next release. If the bugfix should go in sooner than that, I can cherry-pick
that into our fixes. Let me know.

Merged into next/drivers. I noticed git.linaro.org is really slow though,
maybe you should look into getting a kernel.org account instead? It took about

BTW, I guess I could have put this in the commit message, but the

by this (and some other related patches):

* [PATCH 0/2] Add reboot modes for LEGO MINDSTORMS EV3
From: David Lechner @ 2018-01-12 2:21 UTC (permalink / raw)
To: linux-arm-kernel
This series adds a new device tree node to declare a special memory
address that is used by the I2C bootloader on LEGO MINDSTORMS EV3
to boot into a special firmware update mode and enables the required
module to use it.

This adds a new node for reboot modes on LEGO MINDSTORMS EV3. The EV3's
bootloader looks for a magic number in the ARM local RAM and if found,
it will boot into a special firmware update mode where the flash memory
can be written via USB.
This has been testing working using the command:
# systemctl reboot loader

* [PATCH 2/2] ARM: davinci_all_defconfig: enable SYSCON_REBOOT_MODE
From: David Lechner @ 2018-01-12 2:21 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1515723685-19286-1-git-send-email-david@lechnology.com>
This enables SYSCON_REBOOT_MODE as a module. This is used by LEGO
MINDSTORMS EV3 to reboot into a special firmware update mode.

Doh. I forgot to rebase, so this won't apply cleanly. V2 coming right up.

* [PATCH v2 0/2] Add reboot modes for LEGO MINDSTORMS EV3
From: David Lechner @ 2018-01-12 2:29 UTC (permalink / raw)
To: linux-arm-kernel
This series adds a new device tree node to declare a special memory
address that is used by the I2C bootloader on LEGO MINDSTORMS EV3
to boot into a special firmware update mode and enables the required
module to use it.
v2 changes:
* rebase on linux-davinci/master

This adds a new node for reboot modes on LEGO MINDSTORMS EV3. The EV3's
bootloader looks for a magic number in the ARM local RAM and if found,
it will boot into a special firmware update mode where the flash memory
can be written via USB.
This has been testing working using the command:
# systemctl reboot loader

Downstream doesn't use 0x0 to denote 0. I am fine with this, if
someone has a concern or issue with it we can change it before merging.

We could pad this with leading 0's but I find this much easier
to read.

Ok. Left the tags there, but didn't merge into fixes since we're late
in -rc and this didn't seem critical at this time.
