According to the explanations below, "superseded" means, that either a

Hi,
The reason for a lower framerate must not necessarily be in the program,
it can be the hardware - either the clock frequency, your camera is driven

Hi Mauro,
I missed the 4.3 cycle completely, so, this should clean up my backlog.
There are still PXA patches outstanding, but Robert wanted to work a bit
more on them.
The following changes since commit 9ddf9071ea17b83954358b2dac42b34e5857a9af:
Merge tag 'v4.3-rc1' into patchwork (2015-09-1
Hi Laurent, Josh,
It's ok not to CC me immediately if it's expected, that patches will be
further forwarded (by Josh in this case) to me. And it helps, that Josh
has collected all Atmel ISI patches in a git tree branch - thanks! But,

Hi Josh,
Sorry, I missed the 4.3 merge cycle, but isn't this patch a fix? Isn't it
fixing soc-camera / atmel-isi on a specific platform, where the clock name
is longer, than currently supported? Is this platform in the mainline and
its current camera support is broken because of this? In such a
