From 40eca140c404505c09773d1c6685d818cb55ab1a Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 14 Feb 2016 00:41:06 -0200 Subject: [PATCH] [media] mn88473: add DVB-T2 PLP support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Adds PLP ID filtering for DVB-T2. It is untested as I don't have any signal having PLP ID other than 0. There is only 2 extra registers, 0x32 and 0x36 on bank2, that are programmed for DVB-T2 but not for DVB-T and all the rest are programmed similarly - so it is likely PLP. Pridvorov reported successfully testing it in Russia with m-PLP streams, on both Vladivostok and Moskow.
