linux-toradex.git/drivers/media/dvb-frontends, branch v4.4.41 Linux kernel for Apalis and Colibri modules mb86a20s: fix demod settings 2016-10-28T07:01:30+00:00 Mauro Carvalho Chehab mchehab@osg.samsung.com 2016-09-04T13:43:53+00:00 68bf9d10b0f0248d44e62d38d4e7a8fc5b409599 commit 505a0ea706fc1db4381baa6c6bd2e596e730a55e upstream. With the current settings, only one channel locks properly. That's likely because, when this driver was written, Brazil were still using experimental transmissions. Change it to reproduce the settings used by the newer drivers. That makes it lock on other channels.

commit 505a0ea706fc1db4381baa6c6bd2e596e730a55e upstream.

With the current settings, only one channel locks properly.
That's likely because, when this driver was written, Brazil
were still using experimental transmissions.

Change it to reproduce the settings used by the newer drivers.
That makes it lock on other channels.

Tested with both PixelView SBTVD Hybrid (cx231xx-based) and
C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

mb86a20s: fix the locking logic 2016-10-28T07:01:30+00:00 Mauro Carvalho Chehab mchehab@osg.samsung.com 2016-09-04T13:16:18+00:00 177251ecc6f4c62986bf326c6505dd9caef1d1ea commit dafb65fb98d85d8e78405e82c83e81975e5d5480 upstream. On this frontend, it takes a while to start output normal TS data. That only happens on state S9. On S8, the TS output is enabled, but it is not reliable enough. However, the zigzag loop is too fast to let it sync. As, on practical tests, the zigzag software loop doesn't seem to be helping, but just slowing down the tuning, let's switch to hardware algorithm, as the tuners used on such devices are capable of work with frequency drifts without any help from software.

tda1004x: only update the frontend properties if locked 2016-03-03T23:07:14+00:00 Mauro Carvalho Chehab mchehab@osg.samsung.com 2016-02-03T19:33:48+00:00 e862efec7272eab9950ca329eceda7fec272fd20 commit e8beb02343e7582980c6705816cd957cf4f74c7a upstream. The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning.
