106ff9e013 Revert "[media] DVB: dvb_frontend: off by one in dtv_property_dump()"
This reverts commit a3e4adf274f86b2363fedaa964297cb38526cef0.

As pointed by Andread Oberritter <obi@linuxtv.org>:

	That's wrong, because the array size is DTV_MAX_COMMAND + 1.
	Using the ARRAY_SIZE macro instead might reduce the confusion.

Also, changeset 3995223038 already fixed this issue.

243bf1a24d [media] cx88: properly maintain decoder config when using MPEG encoder
The cx88 driver would force core->input to always be zero when doing the
the request_acquire().  While it wasn't actually changing the input register
in the hardware, the driver makes decision based on the current input.  In
particular, it decides whether to do things like enabling the comb filter
when on a composite input but disabling it on s-video.  So for example, on
the HVR-1300, using the s-video input with the MPEG encoder would end up with
the video decoder core configured as though the input type were composite.

In short, the driver state did not match the hardware state.

This patch does two things:

1.  It forces the input to zero only if actually switching to DVB mode.  This
prevents the input from changing when the blackbird driver opens the device.

2.  Keep track of what the input was set to when switching to DVB, and reset
it back when done.  This eliminates a condition where for example the user
had the analog side of the board set to capture on the s-video input, then
he used DVB for a bit, then the analog input would unexpectedly be set to
the tuner input.

c53f9f00e5 [media] redrat3: improve compat with lirc userspace decode
This is admittedly a bit of a hack, but if we change our timeout value
to something longer and fudge our synthesized trailing space sample
based on the initial pulse sample, rc-core decode continues to work just
fine with both rc-6 and rc-5, and now lirc userspace decode shows proper
repeats for both of those protocols as well. Also tested NEC
successfully with both decode options.

We do still need a reset timer callback using the hardware's timeout
value to make sure we actually process samples correctly, regardless of
our somewhat hacky timeout and synthesized trailer above.

This also adds a missing del_timer_sync call to the module unload path.

f5f2cc646a [media] rc-core support for Microsoft IR keyboard/mouse
This is a custom IR protocol decoder, for the RC-6-ish protocol used by
the Microsoft Remote Keyboard, apparently developed internally at
Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and
transceiver requirements and specifications document, which also touches
on this IR keyboard/mouse device.

Its a standard keyboard with embedded thumb stick mouse pointer and
mouse buttons, along with a number of media keys. The media keys are
standard RC-6, identical to the signals from the stock MCE remotes, and
will be handled as such. The keyboard and mouse signals will be decoded
and delivered to the system by an input device registered specifically
by this driver.

Successfully tested with multiple mceusb-driven transceivers, as well as
with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware
with enough sampling resolution should be able to use this decoder,
nothing about it is at all receiver-hardware-specific.

This work is inspired by lirc_mod_mce:

The documentation there and code aided in understanding and decoding the
protocol, but the bulk of the code is actually borrowed more from the
existing in-kernel decoders than anything. I did recycle the keyboard
keycode table, a few defines, and some of the keyboard and mouse data
parsing bits from lirc_mod_mce though.

Special thanks to James Meyer for providing the hardware, and being
patient with me as I took forever to get around to writing this.

callback routine to ensure we don't get any stuck keys, and used
symbolic names for the keytable. Also cc'ing Florian this time, who I
believe is the original mod-mce author...

8afe9119e2 [media] media, Micronas dvb-t: Fix mem leaks, don't needlessly zero mem, fix spelling
In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3
small issues:

 1) When the 'fw' variable goes out of scope we'll leak the memory
 allocated to it by request_firmware() by neglecting to call
 release_firmware().

 2) After a successful request_firmware() we allocate fw->size bytes
 of memory using kzalloc() only to immediately overwrite all that
 memory with memcpy(), so asking for zeroed memory seems like wasted
 effort - just use kmalloc().

 3) In one of the error messages "no memory" lacks a space and is
 written as "nomemory".

This patch fixes all 3 issues.

7498469f61 [media] marvell-cam: Allow selection of supported buffer modes
The Marvell camera core can support all three videobuf2 buffer modes, which
is slick, but it also requires that all three modes be built and present,
even though only one is likely to be used.  This patch allows the supported
modes to be selected at configuration time, reducing the footprint of the
driver.  Prior to this patch, the MMP camera driver looked like this:

mmp_camera             19092  0
videobuf2_core         15542  1 mmp_camera
videobuf2_dma_sg        3173  1 mmp_camera
videobuf2_dma_contig     2188  1 mmp_camera
videobuf2_vmalloc       1718  1 mmp_camera
videobuf2_memops        2100  3 videobuf2_dma_sg,videobuf2_dma_contig,videobuf2_vmalloc

Afterward, instead, with scatter/gather only configured:

mmp_camera             16021  0
videobuf2_core         15542  1 mmp_camera
videobuf2_dma_sg        3173  1 mmp_camera
videobuf2_memops        2100  1 videobuf2_dma_sg

The total goes from 43,813 bytes to 36,836.

The emphasis has been on simplicity and minimal #ifdef use rather than on
squeezing out every possible byte of code.  For configuration, the driver
simply looks at which videobuf2 modes have been configured in and supports
them all; it's simplistic but should be good enough.

The cafe driver is set to support vmalloc and dma-contig; mmp supports only
dma-sg, since that's the only mode that really makes sense to use.

analog tuner not initialised).

Initialise the analog tuner properly and hook up the DVB tuner and demodulator.

there's an issue with the aerial and signal boosters here that is causing

fd0b0814a4 [media] dvb: don't cause missing symbols for drxk/tda18271c2dd
If those demods are unselected, but a bridge driver requires them,
produce a runtime message, instead of missing symbols.

5eee2bb270 [media] drxk: Add a fallback method for QAM parameter setting
The QAM standard is set using this scu_command:
	SCU_RAM_COMMAND_STANDARD_QAM |
	SCU_RAM_COMMAND_CMD_DEMOD_SET_PARAM

The driver implements a version that has 4 parameters, however,
Terratec H5 needs to break this into two separate commands, otherwise,
DVB-C doesn't work.

With this fix, scan is now properly working and getting the
channel list:
>>> tune to: 609000000:INVERSION_AUTO:5217000:FEC_3_4:QAM_256
>>> tuning status == 0x00
>>> tuning status == 0x07
>>> tuning status == 0x1f

0x0093 0x0026: pmt_pid 0x0758 (null) -- SporTV2 (running, scrambled)
0x0093 0x0027: pmt_pid 0x0748 (null) -- SporTV (running, scrambled)

7558977a4a [media] drxk: Improve the scu_command error message
Now, it outputs:

[10927.639641] drxk: SCU_RESULT_INVPAR while sending cmd 0x0203 with params:
[10927.646283] drxk: 02 00 00 00 10 00 07 00 03 02                    ..........

Better than ERROR -3. This happens with Terratec H5 firmware.

It adds 2 new error conditions, and something useful to track
what the heck is that.

I suspect that the scu_command is dependent on the firmware
revision.

90796acad0 [media] drxk: Improves the UIO handling
The driver is too limited: it assumes that UIO is used only for
controlling the antenna, and that only UIO-1 is in usage. However,
from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems
that H7 needs to use all 3. So, make the code generic enough to handle
the most complex scenario. For now, only antena GPIO can be specified,
but is is easier now to add the other GPIO/UIO needs.
