Hello,

On 28/09/2021 11:42:56+0300, Claudiu Beznea wrote:
Group constants and addresses loading. This commit prepares the field for
the next one. Added fixes tag on this commit as the next one will fail
to apply if backported alone to older kernels.

The proper notation is to use Depends-on: on the next patch.

At the moment this patch has no sha1 associated so I will ask Nicolas to
add the Depends-on when he will take it. Do you see other options?

Depends-on added when queuing on at91-fixes.

Thanks, best regards,
Nicolas
