From f2e52cd17622eed39576f113b77bbd18c577e308 Mon Sep 17 00:00:00 2001 From: Manu Abraham Date: Mon, 19 Nov 2007 16:44:47 -0300 Subject: [PATCH] V4L/DVB (9442): Revert back previous change to 90MHz Note: * At High Symbol Rates we do not have enouph machine cycles to handle the incoming symbols and hence might run into problems at the very end of the specified definition * Most of the equations have been calculated for a master clock of 99 MHz, running at 90MHz, raises lot of issues such as the need to recalculate all of them , which is eventually very painful.
