Hi Arun,

This patch sets looks very good.
Please check my comments below.

Here, I would add some define name to avoid magic number.
Secondly, why wasn't this padding added in s5p_mfc_enc_calc_src_size_v6/v7?
enc_calc_src_size is called in s_fmt, so it seems the best place to adjust
buffer/plane sizes.
