The VOP-binding specifies the aclk, dclk and hclk clocks. The NPLL is a possible source for quite a lot of peripherals on the rk3368 aclk_cci_pre, sclk_tcp, vepu/vdpu, hevc, isp, gpu, gmac So it's definitly not dedicated to the VOP, and thus should not change frequency for the VOP alone, because that could affect other blocks.
