Typically, tuners with TUA603x PLLs can benefit from setting the AGC TOP value to something else. This patch includes code to set the AGC TOP to 103 dBuV for the Thomson DTT-761x tuners, which I have experimentally verified gives the best SNR readings, increasing SNR by about 0.19 dB over the default value. Other tuners can make use of this as well. For example, the separate LG TDVS-H06xF driver's only difference from dvb-pll is this same setting of AGC TOP value.
