fc44328478 [media] cx24120: Convert read_ber to retrieve from cache
Instead of reading BER again for DVBv3 call, use the value from the cache.

ddcb252e41 [media] cx24120: Add in dvbv5 stats for bit error rate
DVBv3 is a legacy API. Drivers should use DVBv5, in order to support
modern applications. So, implement BER using dvbv5.

The values written by cx24120 are never checked. So, remove the
check here too. That's said, the best would be to do the reverse,
but globally: to properly handle the error codes.

270e70713b [media] cx24120: Add missing command to cx24120_check_cmd
This patch adds in a missing command to cx24120_check_cmd. This part
of the old reverse engineered driver was quite hard to follow - it's
presumed the compiler did some neat optimisation that wasn't easy to
decode. This command was checked for in that version but not copied
across to the new switch statement.

For reference, old reverse engineered code:
xxzz = cmd->id - 0x11;			// look for specific message id
if ( xxzz <= 0x13 ) {
	msg_cmd_mask = 1 << xxzz;
	//0x0F8021 // if cmd_id 17 or 22 or 33-36, 42, 47, 57-61 etc. disable mpeg output
	if ( msg_cmd_mask & 0x0F8021 ) {	// 000011111000000000100001b
		cx24120_msg_mpeg_output_global_config(state, 0);
		msleep(100);
		state->dvb_s2_mode &=  0xFD;	// reset mpeg out enable flag
	}

5afc9a25be [media] Add support for TechniSat Skystar S2
This patch adds support for the Technisat Skystar S2 - this
has been tried before but the cx24120 driver was a bit out of shape
and it didn't got any further:

https://patchwork.linuxtv.org/patch/10575/

It is an old card, but currently being sold off for next to nothing,
so it's proving quite popular of late. Noticing it's quite similar
to the cx24116 and cx24117 I've rewritten the driver in a similar way.

There were a few registers and commands from those drivers
missing from this one I've tested out and found they do something so
they've been added in to speed up tuning and to make get_frontend
return something useful.

699dcffc52 [media] rtl2832: add support for GoTView MasterHD 3 USB tuner
GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.

It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20

The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/

Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.

As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.

For some reason, the old I2C write method sporadically fails. Thus the
need for an option to only use the new I2C write method supported by the
RTL2832.

f3f8ef2274 [media] dib0070: Fix indenting
The indentation on this driver were deadly broken. On lots
of places, it was using 4 spaces instead of tab to indent.
On other parts, it were using tabs.

Also, on several places, it were not even being properly aligned,
as reported by smatch:
	drivers/media/dvb-frontends/dib0070.c:179 dib0070_set_bandwidth() warn: inconsistent indenting

	drivers/media/dvb-frontends/dib0070.c:713 dib0070_reset() warn: inconsistent indenting

My first idea were to leave it as-is or to just touch the above.

However, this won't be fixing anything. So, as painful as it
is, let's fix indentation globally on the driver, and then
address the inconsistencies.

Hopefully, this driver doesn't have much patches, so it likely
won't conflict to any other patch during this merge window.

Besides the big size of this patch, no functional changes
were done.

00c78a3728 dvb-frontends: use IS_REACHABLE() instead of IS_ENABLED()
Changeset 9b174527e7 added this new macro, ensuring that it
is true only if the function is actually reachable.

However, newer drivers were added since when it was written.
So, change those drivers to also use it.

9b174527e7 [media] Add and use IS_REACHABLE macro
In the media drivers, the v4l2 core knows about all submodules
and calls into them from a common function. However this cannot
work if the modules that get called are loadable and the
core is built-in. In that case we get

drivers/built-in.o: In function `set_type':
drivers/media/v4l2-core/tuner-core.c:301: undefined reference to `tea5767_attach'
drivers/media/v4l2-core/tuner-core.c:307: undefined reference to `tea5761_attach'
drivers/media/v4l2-core/tuner-core.c:349: undefined reference to `tda9887_attach'
drivers/media/v4l2-core/tuner-core.c:405: undefined reference to `xc4000_attach'

This was working previously, until the IS_ENABLED() macro was used
to replace the construct like

 #if defined(CONFIG_DVB_CX24110) || (defined(CONFIG_DVB_CX24110_MODULE) && defined(MODULE))

with the difference that the new code no longer checks whether it is being
built as a loadable module itself.

To fix this, this new patch adds an 'IS_REACHABLE' macro, which evaluates
true in exactly the condition that was used previously. The downside
of this is that this trades an obvious link error for a more subtle
runtime failure, but it is clear that the change that introduced the
link error was unintentional and it seems better to revert it for
now. Also, a similar change was originally created by Trent Piepho
and then reverted by teh change to the IS_ENABLED macro.

Ideally Kconfig would be used to avoid the case of a broken dependency,
or the code restructured in a way to turn around the dependency, but either
way would require much larger changes here.

Fixes: 7b34be71db ("[media] use IS_ENABLED() macro")

Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.

We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.

This gets rid of some checkpatch errors:

WARNING: Prefer [subsystem eg: netdev]_info([subsystem]dev, ... then dev_info(dev, ... then pr_info(...  to printk(KERN_INFO ...
+#define lg_info(fmt, arg...)	printk(KERN_INFO "lgdt3306a: " fmt, ##arg)

0d117901b6 [media] rtl2832: remove internal mux I2C adapter
There was 2 muxed I2C adapters, one for demod tuner bus and one for
internal use. Idea of internal I2C adapter was to force I2C repeater
close when demod access its registers. Driver has also delayed work
queue based method to close I2C repeater.

After regmap conversion internal I2C adapter based repeater close
left unused - only work queue method was in use. We could not use
internal mux adapter method with regmap as it makes recursive regmap
call, which causes deadlock as regmap has own locking. Due to that
remove whole method totally.

legacy DVB binding. Platform bus is pseudo-bus provided by kernel
driver model and it fits cases like that, where any other busses

    dib8000_write_word(state, 1947, reg | (1<<14) | ((upd_demod_gain_period >> 16) & 0xFF));

So, it should be declared as u32.

ffe300107d [media] stv090x: add an extra protetion against buffer overflow
As pointed by smatch:
	drivers/media/dvb-frontends/stv090x.c:2787 stv090x_optimize_carloop() error: buffer overflow 'car_loop_apsk_low' 11 <= 13
	drivers/media/dvb-frontends/stv090x.c:2789 stv090x_optimize_carloop() error: buffer overflow 'car_loop_apsk_low' 11 <= 13
	drivers/media/dvb-frontends/stv090x.c:2791 stv090x_optimize_carloop() error: buffer overflow 'car_loop_apsk_low' 11 <= 13
	drivers/media/dvb-frontends/stv090x.c:2793 stv090x_optimize_carloop() error: buffer overflow 'car_loop_apsk_low' 11 <= 13
	drivers/media/dvb-frontends/stv090x.c:2795 stv090x_optimize_carloop() error: buffer overflow 'car_loop_apsk_low' 11 <= 13

The situation of a buffer overflow won't happen, in practice,
with the current values of car_loop table. Yet, the entire logic
that checks for those registration values is too complex. So,
better to add an explicit check, just in case someone changes
the car_loop tables causing a buffer overflow by mistake.

This also helps to remove several smatch warnings, with is good.

a2ea556117 [media] stv090x: remove export symbol for stv090x_set_gpio()
Drivers that use dvb_attach can have just one exported symbol,
or they will cause compilation breakages depending on the
selected frontends.

As Jim reported:
drivers/built-in.o: In function `technisat_usb2_set_voltage':
technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio'
make: *** [vmlinux] Error 1

That happens because, on his configuration, the configuration
is:

	CONFIG_DVB_USB=y
	CONFIG_DVB_STV090x=m

Luis proposed ar way to fix, but that would just force the
STV090x to be selected, even if one wants to use a device
with a different frontend.

Instead, let's do the right thing: move set_gpio to the
configuration structure and fill it during dvb_attach().

This way, the driver can still call it, and dvb_attach()
will load stv090x module only if the device really needs it.

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.

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

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.

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.

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().

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.

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.

886da6ac33 [media] stv0367: Remove an unused parameter
cab_state->modulation is initialized with a wrong value:

drivers/media/dvb-frontends/stv0367.c:3000:42:     int enum stv0367cab_mod

as it was declared as "enum stv0367cab_mod". While it could be fixed,
there's no value on it, as this is never used.

So, just remove the modulation from cab_state structure.

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.
