not really sure what you mean here.
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.
