Hi Josh,

Does this patch apply because of the new enhancement that you had
proposed in "media: atmel-isi: parse the DT parameters for
vsync/hsync/pixclock polarity" or does it apply even before?
Is it a fix that applies to older kernels?

So, should I wait for the enhancements to enter media git tree or can I
take them anyway?

Bye,
