Mauro Carvalho Chehab 667c952e71 [media] cx22700: Fix potential buffer overflow
As new FEC types were added, we need a check to avoid overflows:
	drivers/media/dvb-frontends/cx22700.c:172 cx22700_set_tps() error: buffer overflow 'fec_tab' 6 <= 6
	drivers/media/dvb-frontends/cx22700.c:173 cx22700_set_tps() error: buffer overflow 'fec_tab' 6 <= 6

Mauro Carvalho Chehab b9f62ffe05 [media] stb0899: don't go past DiSEqC msg buffer
As reported by spatch:
	drivers/media/dvb-frontends/stb0899_drv.c:720 stb0899_send_diseqc_msg() error: buffer overflow 'cmd->msg' 6 <= 7

The buffer size is 6 and not 8. Anyway, the best is to use sizeof(),
to avoid such mistakes.

Mauro Carvalho Chehab 1011d24a21 [media] stv090x: Fix delivery system setting
As sparse complains:
	drivers/media/dvb-frontends/stv090x.c:3471:30: warning: mixing different enum types
	drivers/media/dvb-frontends/stv090x.c:3471:30:     int enum fe_delivery_system  versus
	drivers/media/dvb-frontends/stv090x.c:3471:30:     int enum stv090x_delsys

There's actually an error when setting the delivery system on
stv090x_search(): it is using the DVBv5 macros as if they were
the stv090x ones.

Instead, we should convert between the two namespaces, returning
an error if an unsupported delivery system is requested.

Antti Palosaari 0b0d96281f [media] af9033: fix AF9033 DVBv3 signal strength measurement
Previous patch changes used signal strength firmware register from
0x800048 to 0x80004a in case of AF9033/AF9035 chip. In practice
reported values were running upside-down, when RR strength increases
reported value decreases and vice versa. That is because of 0x80004a
returns values that are dBm scale, but negative RF strength dBm
returned as positive number.

0x800048 returns 0-100, like percentage
0x80004a returns 0-255 dBm, without a negative sign

So restore old measurement now.

nibble.max f4df95bcbb [media] m88ds3103: add support for the demod of M88RS6000
M88RS6000 is the integrated chip, which includes tuner and demod. Its
internal demod is similar with M88DS3103 except some registers
definition.

The main different part of this internal demod from others is its
clock/pll generation IP block sitting inside the tuner die. So clock/pll
functions should be configed through its tuner i2c bus, NOT its demod
i2c bus.

The demod of M88RS6000 need the firmware: dvb-demod-m88rs6000.fw

Dan Carpenter 66ae9fc237 [media] stv090x: remove indent levels in stv090x_get_coldlock()
This code is needlessly complicated and checkpatch.pl complains that we
go over the 80 characters per line limit.

If we flip the "if (!lock) {" test to "if (lock) return;" then we can
remove an indent level from the rest of the function.

We can add two returns in the "if (state->srate >= 10000000) {"
condition and move the else statement back an additional indent level.

There is another "if (!lock) {" check which can be removed since we have
already checked "lock" and know it is zero at this point.  This second
check on "lock" is also a problem because it sets off a static checker
warning.  I have reviewed this code for some time to see if something
else was intended, but have concluded that it was simply an oversight
and should be removed.  Removing this duplicative check gains us an
third indent level.

Ulrich Eckhardt 8c5bcded11 [media] ds3000: fix LNB supply voltage on Tevii S480 on initialization
The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not
automatically power down. This blocks other receivers connected
to a satellite channel router (EN50494), since the receivers can not send the
required DiSEqC sequences when the Tevii card is connected to a the same SCR.

This patch switches off the LNB supply voltage on initialization of the frontend.

Mauro Carvalho Chehab 52ee29fe94 [media] drxk: Fix debug printks
This patch partially reverts 0fb220f2a5. What happened is
that the conversion of debug messages to use pr_debug() was a
bad idea, because one needing to debug would need to both
enable debug level via a modprobe parameter, and then to
enable the dynamic printk's.

So, for now, let's use printk() directly at dprintk().

Linus Torvalds ea584595fc This is the bulk of GPIO changes for the v3.18 development
cycle:
 
 - Increase the default ARCH_NR_GPIO from 256 to 512. This
   was done to avoid having a custom <asm/gpio.h> header for
   the x86 architecture - GPIO is custom and complicated
   enough as it is already! We want to move to a radix to
   store the descriptors going forward, and finally get rid
   of this fixed array size altogether.
 
 - Endgame patching of the gpio_remove() semantics initiated
   by Abdoulaye Berthe. It is not accepted by the system that
   the removal of a GPIO chip fails during e.g. reboot or
   shutdown, and therefore the return value has now painfully
   been refactored away. For special cases like GPIO expanders
   on a hot-pluggable bus like USB, we may later add some
   gpiochip_try_remove() call, but for the cases we have now,
   return values are moot.
 
 - Some incremental refactoring of the gpiolib core and ACPI
   GPIO library for more descriptor usage.
 
 - Refactor the chained IRQ handler set-up method to handle
   also threaded, nested interrupts and set up the parent IRQ
   correctly. Switch STMPE and TC3589x drivers to use this
   registration method.
 
 - Add a .irq_not_threaded flag to the struct gpio_chip, so
   that also GPIO expanders that block but are still not
   using threaded IRQ handlers.
 
 - New drivers for the ARM64 X-Gene SoC GPIO controller.
 
 - The syscon GPIO driver has been improved to handle the
   "DSP GPIO" found on the TI Keystone 2 SoC:s.
 
 - ADNP driver switched to use gpiolib irqchip helpers.
 
 - Refactor the DWAPB driver to support being instantiated
   from and MFD cell (platform device).
 
 - Incremental feature improvement in the Zynq, MCP23S08,
   DWAPB, OMAP, Xilinx and Crystalcove drivers.
 
 - Various minor fixes.

Akihiro Tsukada f5d82a75e6 [media] tc90522: add driver for Toshiba TC90522 quad demodulator
This patch adds driver for tc90522 demodulator chips.
The chip contains 4 demod modules that run in parallel and are independently
controllable via separate I2C addresses.
Two of the modules are for ISDB-T and the rest for ISDB-S.
It is used in earthsoft pt3 cards.

Note that this driver does not init the chip,
because the initilization sequence / register setting is not disclosed.
Thus, the driver assumes that the chips are initilized externally
by its parent board driver before fe->ops->init() are called.
Earthsoft PT3 PCIe card, for example, contains the init sequence
in its private memory and provides a command to trigger the sequence.

I traced this to a NULL i2c_adapter parent pointer when cx24123 creates its own
i2c adapter. The acpi_i2c_install_space_handler function appeared in 3.17, so
that's probably why this hasn't been seen before.

AF903x/IT913x demod provides clock source(s). It seems that this
clock source is used for integrated RF tuner of IT913x. It is
enabled by default, but firmware disables it automatically when
suspend is requested (suspend_flag (0x004c) + trigger_ofsm
(0x0000)). Automatic disable behavior seems to be similar for both
AF903x and IT913x I tested, though there is no likely any real
clock user in a case of AF903x.

Add a variable to keep track if firmware is loaded or not and skip parts of the
initialization if fw is already loaded. Resume from sleep with a different
command compared to initial power up and run command 85 after resume command.
This behaviour is observed when using manufacturer provided binary-only si2168
driver for TechnoTrend CT2-4400.

Antti Palosaari 9dc0f3fe3f [media] af9033: feed clock to RF tuner
IT9135 RF tuner clock is coming from demodulator. We need enable it
early in demod init, before any tuner I/O. Currently it is enabled
by tuner driver itself, but it is too late and performance will be
reduced as some registers are not updated correctly. Clock is
disabled automatically when demod is put onto sleep.

Olli Salonen 868736ad34 [media] sp2: Add I2C driver for CIMaX SP2 common interface module
Driver for the CIMaX SP2 common interface chip. It is very much based on
the existing cimax2 driver for cx23885, but should be more reusable. The
product has been sold with name Atmel T90FJR as well and the data sheets
for that chip seem to be publicly available.

It seems that the USB device that I have and the cx23885 based devices will
need to interact differently with the chip for the CAM operations. Thus
there is one callback function that is passed on to the sp2 driver
(see function sp2_ci_op_cam for that one).

IRQ functionality is not included currently (not needed by USB devices
and I don't have a PCIe device for development).

Olli Salonen 389ce3984b [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.

There is no need to print module name nor function name as those
are done by kernel logging system when dev_xxx logging is used and

refusing tuning attempt. Due to that, hard code modulation to QPSK
in case of DVB-S.
