From 389ce3984b337690ed5124f2379fc8c3f3975c53 Mon Sep 17 00:00:00 2001 From: Olli Salonen Date: Mon, 11 Aug 2014 16:58:10 -0300 Subject: [PATCH] [media] si2168: add ts_mode setting and move to si2168_init Luis Alves submitted a TS mode patch to si2168 earlier, but the patch was rejected due to a small issue. Here is a working version. Also, setting of TS mode is moved from si2168_set_frontend to si2168_init. This patch adds the TS mode as a config option for the si2168 demod: - ts_mode added to config struct. - Possible (interesting) values are * Parallel mode = 0x06 * Serial mode = 0x03 Currently the modules using this demod only use parallel mode. Patches for these modules later in this patch series.
