USE the adv7441.

when input HDMI  to PORT A, maybe one source of the video(1080 P60) input is ok,but another source of the video(1080 P60) not ,

so when input unsuccessful, read the register, is that 

TMDS_PORT_A_ACTIVEVIDEO_PLL_LOCKEDTMDS_CLK_A_RAW   lock ok,

and  sometimes V_LOCKED_RAW    VERT_FILTER_LOCKED  locked unfair.

but  in the datasheet,the unfair register is read only.

so I want to know the reason of it?

what‘s  the  factor with the register  V_LOCKED_RAW    VERT_FILTER_LOCKED ?
