Hi Hayama-san,

Thank you for the patch.

I've applied the patch to my tree. I'll wait for your reply regarding my 
comments to the first patch and will then send a pull request for both.

Thank you. As I already mentioned in my other email, I'm all good with
your suggestions.

[PATCH v2 2/2] v4l: vsp1: Always enable virtual RPF when BRU is in use

2014-11-26 Thread Takanari Hayama
Regardless of a number of inputs, we should always enable virtual RPF
when BRU is used. This allows the case when there's only one input to
BRU, and a size of the input is smaller than a size of an output of BRU.
