The vop2_output_if_is_* defines are used only once. Maybe a big:

switch (id) {
	case ROCKCHIP_VOP2_EP_HDMI0:
	case ROCKCHIP_VOP2_EP_HDMI1:
		...
}

would look a bit better overall.


actually the output_if check will be used in more place, such as a RB_SWAP for DP and hdmi

at YUV444 output mode(I lost in this version, I will add it in next).

So I would like keep it.

Not sure if this will change with future extensions, but currently

so maybe better write it like this

+		clock = vop2_set_intf_mux(vp, rkencoder->crtc_endpoint_id, polflags);
clock is set to potentially different values in this loop and the last
value is taken. Without a further description or check this looks wrong.

If we attach more encoder/connector on one vp, the clock will calculate more than once

but with a same result.

I will add comment in next version.

It a little difficult to find a proper way to do the check, as not every soc need all these phandles.

Do i need check it per soc?
