On platforms that have CONFIG_HZ set to 100, the power ramp time effectively
ends up being 10ms. However, on those that have a higher CONFIG_HZ, the time
ends up *actually* being 5ms, which doesn't allow enough time for the hardware
to be fully powered up before attempting to address it via i2c.
Change the constant to 10ms, which is long enough for the hardware to power
up, and won't really be anymore time than it was previously on platforms
with CONFIG_HZ being 100.
Credit goes to Mauro Carvalho Chehab and Gerd Hoffmann who previously
investigated this issue.

The search for matching extension units fails to take account of the
current chain. In the case where you have two distinct video chains,
both containing an XU with the same GUID but different unit ids, you
will be unable to perform a mapping on the second chain because entity
on the first chain will always be found first
Fix this by only searching the current chain when performing a control
mapping. This is analogous to the search used by uvc_find_control(),
and is the correct behaviour.

The error propagation changeset c23bf4402 broke the DVB-T
code.
The legacy way for propagate errors was:
do {
status = foo_func()
if (status < 0)
break;
} while (0);
return status;
However, on a few places, it was doing:
do {
switch(foo) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
switch(foo2) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
...
} while (0);
return (status)
The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.
Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

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.

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.

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.

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

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.

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).

If those demods are unselected, but a bridge driver requires them,
produce a runtime message, instead of missing symbols.

Use a name convention for the firmware file that matches on the
current firmware namespacing. Also, add it to the firmware
download script.

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)

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.

DRX-K configuration is interesting when writing/testing
new devices. Add an info line showing the discovered info.

Terratec H5 doesn't require to switch mode, but generates
an error due to this logic. Also, GPIO's are board-dependent.
So, add it at the board config struct.

The set mode routines assume that state were changed to the
new mode, otherwise, they'll fail.

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.

On em28xx, tda18271C2 is accessible when the i2c port
is not touched. Touching on it breaks the driver.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
All I2C logs we got for em28xx does that. With Terratec H5, at
400MHz speed, it seems that this is required, to avoid having
troubles at the I2C bus.

The microcode firmware provided on Terratec H5 seems to be
different. Add a parameter to allow specifying a different
firmware per-device.

Instead of using #ifdef I2C_LONG_ADR for some devices, convert
it into a parameter. Terratec H5 logs from the original driver
seems to need this mode.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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.

This is a complex driver. Adding support for other devices with drxk
requires to be able to debug it and see where it is failing. So, add
optional printk messages to allow debugging it.
