From 17e67d4c7fb7515ce98d3eb5de00c2575800818b Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 1 Mar 2013 15:20:25 -0300 Subject: [media] mb86a20s: change AGC tuning parameters Use the AGC settings present on a newer device. The initial settings were taken from one of the first devices with mb86a20s, and there are several reports that this is not working properly on some places. So, instead of keeping using it, get the parameters taken from a newer device. Tests are welcomed. Tested also with cx231xx PixelView SBTVD Hybrid with no regressions noticed so far.
