2017-07-20media: dvb_ca_en50221: Refactored dvb_ca_en50221_threadJasmin Jessich
Refactored "dvb_ca_en50221_thread" by moving the state machine into the new function "dvb_ca_en50221_thread_state_machine". This reduces the thread function size and reduces the structural complexity and of course gives us more space to meet the line length goal in the new function.

2017-07-20media: dvb-frontends/stv0367: improve QAM fe_statusDaniel Scheller
While cab_state->state gives a quite accurate indication of the demod signal status, it might be incorrect if cab_algo() wasn't able to determine the exact status, with cab_algo() being the only place where this status was updated from, and it is only called upon tuning to new parameters passed to set_frontend(). Thus, the status will be wrong until the demod is retuned. With the cab_signal_type parsing in read_status(), this results in unusual fe_states like FE_HAS_SIGNAL | FE_HAS_CARRIER | FE_HAS_LOCK, which, while userspace applications check for FE_HAS_LOCK and work fine, leads to missing CNR or UCB stats. Fix this by re-reading CAB_FSM_STATUS and updating cab_state->state() in read_status(). While at it, refactor the fsm/qamfeclock and the fsm->signaltype parsing into separate functions to make things cleaner and deduplicate code. Also, assume full QAM FEC lock equals full FE_STATUS.

2017-07-20media: dvb-frontends/cxd2841er: do sleep on delivery system changeDaniel Scheller
Discovered using w_scan when scanning DVB-T/T2: When w_scan goes from -T to -T2, it does so without stopping the frontend using .sleep. Due to this, the demod operation mode isn't re-setup, but as it still is in STATE_ACTIVE_TC, PLP and T2 Profile are set up, but only retune_active() is called, leaving the demod in T mode, thus not operable on any T2 frequency. Fix this by putting the demod to sleep if priv->system isn't equal to p->delsys. To properly accomplish this, sleep_tc() is split into sleep_tc() and shutdown_tc(), where sleep_tc() will only perform the sleep operation, while shutdown_tc() additionally performs the full demod shutdown (to keep the behaviour when the .sleep FE_OP is called).

2017-07-20media: media/dvb: earth-pt3: fix hang-up in a rare caseAkihiro Tsukada
When a user starts and stops filtering at a demux device too quickly in a very short interval, the user process hangs in uninterruptible sleep, due to an inconsistency of kthread status in the driver. The kthread can be stopped before it starts running its thread function, but the invocation status was partly managed in the kthread function, which resulted in a double kthread_stop() of one kthread.

This enables the driver to properly receive and handle multistream transponders, functionality has been reported working fine by testers with access to such streams, in conjunction with VDR on the userspace side. The code snippet originates from the original vendor's dddvb driver package and has been made working properly with the current in-kernel DVB core API.

2017-07-20media: dvb-frontends: add ST STV0910 DVB-S/S2 demodulator frontend driverDaniel Scheller
This adds a multi frontend driver for the ST STV0910 DVB-S/S2 demodulator frontends. The driver code originates from the Digital Devices' dddvb vendor driver package as of version 0.9.29, and has been cleaned up from core API usage which isn't supported yet in the kernel, and additionally all obvious style issues have been resolved. All camel case and allcaps have been converted to kernel_case and lowercase. Patches have been sent to the vendor package maintainers to fix this aswell. Signal statistics acquisition has been refactored to comply with standards. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.

We know this won't happen as the template name is always "usbvision", so we can easily avoid the warning as well by using this as the format string directly.

This patch enables support for non-Bluecherry labeled solo6110 based PCI cards which have 3 x TW2864B chips and one TW2865. These cards are displayed by lspci -nn as "Softlogic Co., Ltd. SOLO6110 H.264 Video encoder/decoder [9413:6110]" Bluecherry cards have 4 x TW2864A. According to datasheet register 0xFF of TW2864B chips contains value 0x6A or 0x6B depending on revision which being shifted 3 bits right gives value 0x0d. Existing version of solo6x10 fails on these cards with [276582.344942] solo6x10 0000:07:00.0: Probing Softlogic 6110 [276582.402151] solo6x10 0000:07:00.0: Could not initialize any techwell chips [276582.402781] solo6x10: probe of 0000:07:00.0 failed with error -22 Signed-off-by: Anton Sviridenko <anton@corp.bluecherry.net> Acked-by: Andrey Utkin <andrey_utkin@fastmail.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Provide support for the ADV7481 and ADV7482. The driver is modelled with 4 subdevices to allow simultaneous streaming from the AFE (Analog front end) and HDMI inputs though two CSI TX entities. The HDMI entity is linked to the TXA CSI bus, whilst the AFE is linked to the TXB CSI bus. The driver is based on a prototype by Koji Matsuoka in the Renesas BSP, and an earlier rework by Niklas Söderlund.
