Hi Jacopo,
I was planning to merge imx and imx-jpeg on a separate patch series that
would also group drivers from other manufacturers, but, it should be ok
to merge on v3.
I won't be touching the Kconfig menuconfig/if/endif on this series, though.
I'll do that in a more uniform way at the followup series.
The idea would be to have a followup series organizing the drivers
per manufacturer, e. g. make menuconfig would display something
like:
Media platform drivers
Drivers for <manufacturer 1>
<driver name a>
<driver name b>
...
Drivers for <manufacturer 2>
<driver name c>
<driver name d>
...
Drivers for <manufacturer 3>
<driver name e>
<driver name f>
...
...
