It is useless. There is only one physical I2C-adapter.
2nd adapter was added originally due to some plans for allowing only one
demod to access bus at time. But I never implemented proper locking...

That's this tuner:
The credit card sized remote more or less works if I set remote=4,
so I added the hash to get it autodetected. (`more or less' there
meaning sometimes buttons are `stuck on repeat', i.e. ir-keytable -t
keeps repeating the same scancode until i press another button.)

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.

Microsoft's Windows Media Center specification and requirements doc from
2011.03.18 now refers to the former Power Toggle button as the Sleep
Toggle, and recommends using a new moon sleep icon for it. Its the same
key, but its apparently always been meant to put the system to sleep,
not power it off. Adjust accordingly. While we're here, lets also remove
the duplicate KEY_PLAYPAUSE entry.

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.

This code shows signs of having been mucked with over the last five years
or so; things were kind of mixed up. This patch reorders functions into a
more rational organization which, with luck, will facilitate making the
buffer modes selectable at configuration time. Code movement only: no
functional changes here.

The third parameter of module_param is supposed to represent sysfs
file permissions. A value of "1" leads to the following:

total 0
I am changing it to "0" to align with the other module parameters in
this driver.

Based on the work of John Newbigin, Davor Emard and others who contributed
on the mailing lists.
The previous 'support' for this card was a partial merge of John's changes
that, as far as I can tell, never actually got the thing working (no DVB-T,
analog tuner not initialised).
Initialise the analog tuner properly and hook up the DVB tuner and demodulator.
DVB-T and analog now work (though I can't tune every DVB channel, but I think
there's an issue with the aerial and signal boosters here that is causing
me problems).

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

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.

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.

This driver is very big and complex. An error happening in the middle
of any initialization may cause the frontend to not work. So, it
needs to properly propagate error codes internally and to userspace.
Also, printing the error codes at the places it happened helps to
discover were's a bug at the code.
Before this change, a do { } while (0) loop and lots of breaks inside
were used to propagate errors. While this works, if there are
loops inside other loops, it could be easy to forget to add another
break, causing the error to not abort the function.
Also, as not all functions were reporting errors, it is hard to
discover why something failed.

Currently, the only parameter to be configured is the I2C
address. However, Terratec H5 logs shows that it needs a different
setting for some things, and it has its own firmware.
So, move the addr into a config structure, in order to allow adding
the required configuration bits.

The normal 16-bits read routine is called as "Read16_0". This is
due to a flags that could optionally be passed. Yet, on no places
at the code, a flag is passed there.
The same happens with 16-bits write and 32-read/write routines,
and with WriteBlock.
Also, using flags, is an exception: there's no place currently using
flags, except for an #ifdef at WriteBlock.
Rename the function as just "read16", and the one that requires flags,
as "read16_flags".
This helps to see where the flags are used, and also avoid using
CamelCase on Kernel.
