* media: dvb-frontends/stv0910: rework and fix DiSEqC sendDaniel Scheller2018-03-061-9/+10
| | | | | | | | | | | | | | | | | | | | | | Rework both DiSEqC send functions (send_master_cmd() and send_burst()) to utilise the new SET_REG() and SET_FIELD() macros. Esp. due to SET_FIELD(), this makes sure that not all bits (with unrelated purposes) are always rewritten, but only those needed for sending DiSEqC commands. In send_burst(), this makes sure that DISEQC_MODE isn't changed from 3 to 2 inbetween when sending SEC_MINI_A. Also, change both functions to write DISEQC_MODE first before setting DIS_PRECHARGE. This makes diseqc control work more reliable for "fullblown" DiSEqC strings in VDR's diseqc.conf in combination with certain multiswitches.

* media: cxd2099: move driver out of staging into dvb-frontendsDaniel Scheller2018-03-064-0/+759
| | | | | | | | | | | | | | | | | | | | | | | | | According to the TODO file, this driver only landed in staging because of the way device nodes and data transfers are handled. Besides that this way (use of secX devices) has become sort of standard to date (ie. VDR supports this literally since ages via the ddci plugin, TVHeadend received this functionality lately, and minisatip being currently worked on regarding this), most importantly this I2C client only driver isn't even responsible for setting up device nodes, not for handling data transfer and so on, but only serves as interface for the dvb_ca_en50221 subsystem, just like every other DVB card out in the wild, with hard-wired or such flexible CA interfaces. And, it would even work with cards having the cxd2099 controller hard-wired. Also, this driver received quite some love and even is a proper I2C client driver by now. So, as this driver acts as a EN50221 frontend device, move it to dvb-frontends. There is no need to keep it buried in staging. This commit also updates all affected Kconfig and Makefile's, and adds MEDIA_AUTOSELECT depends to ddbridge and ngene.

* media: lgdt3306a: Add QAM AUTO supportBrad Love2018-03-061-9/+33
| | | | | | | | | | | | | | | As configured currently, modulation in the driver is set to auto detect, no matter what the user sets modulation to. This leads to both QAM64 and QAM256 having the same effect. QAM AUTO is explicitly added here for compatibility with scanning software who can use AUTO instead of doing essentially the same scan twice. Also included is a module option to enforce a specific QAM modulation if desired. The true modulation is read before calculating the snr. Changes are backwards compatible with current behaviour.

* media: lgdt3306a: Set fe ops.release to NULL if probedBrad Love2018-03-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If release is part of frontend ops then it is called in the course of dvb_frontend_detach. The process also decrements the module usage count. The problem is if the lgdt3306a driver is reached via i2c_new_device, then when it is eventually destroyed remove is called, which further decrements the module usage count to negative. After this occurs the driver is in a bad state and no longer works. Also fixed by NULLing out the release callback is a double kfree of state, which introduces arbitrary oopses/GPF. This problem is only currently reachable via the em28xx driver.

* media: ABS macro parameter parenthesizationDan Gopstein2018-03-068-16/+10
| | | | | | | | | | | | | | | | | Replace usages of the locally defined ABS() macro with calls to the canonical abs() from kernel.h and remove the old definitions of ABS() This change was originally motivated by two local definitions of the ABS (absolute value) macro that fail to parenthesize their parameter properly. This can lead to a bad expansion for low-precedence expression arguments. For example: ABS(1-2) currently expands to ((1-2) < 0 ? (-1-2) : (1-2)) which evaluates to -3. But the correct expansion would be ((1-2) < 0 ? -(1-2) : (1-2)) which evaluates to 1. Signed-off-by: Dan Gopstein <dgopstein@nyu.edu> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

| | | | | | | | | | | | | | The MaxLinear MxL5xx has support for physical layer scrambling, which was recently added to the DVB core via the new scrambling_sequence_index property. Add required bits to the mxl5xx driver. Picked up from dddvb master, commit 5c032058b9ba ("add support for PLS") by Ralph Metzler <rjkm@metzlerbros.de>, adapted to the different naming of the pls property (pls vs. scrambling_sequence_index).
