By default, the driver enters standby mode with slave tuner output
loop thru enabled and xtal oscillator on.
Not all designs require that slave tuner output loop thru and
xtal oscillator remain active while in standby mode, so two
additional standby modes have been added:
- standby mode with xtal oscillator on (loop thru off)
- total power off

Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:
1) It requires that the scancode to be at the range 00-7f;
2) keycodes should be masked on 7 bits in order for it to work;
3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;
4) it is different than what is done with dvb-usb approach;
5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.
This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
u16 scancode;
u32 keycode;
};
This is very close to what dvb does. So, a further integration with DVB
code will be easy.
While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.
The only notable effect is the redution of about 35% of the ir-common
module size:
text data bss dec hex filename
6721 29208 4 35933 8c5d old/ir-common.ko
5756 18040 4 23800 5cf8 new/ir-common.ko
In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.
This patch itself shouldn't be doing any functional changes.

calibration during attach
On certain master / slave dual tuner configurations, tuning performance
improves when the RF tracking filter calibration is performed sequentially.
This patch allows for the bridge driver to specify this behavior in the
configuration structure at attach-time.
The "cal" module option will continue to override this attach-time
configuration: set cal=0 to prevent RF tracking filter calibration
on startup, and set cal=1 to force it.

KEY_CAMERA is already used for a long time with webcam drivers to take a picture.
On other media drivers, due to the lack of a snapshot button, random KEY codes
were sent, being KEY_SHUFFLE the most used one, probably due to cut-and-paste
from other remotes, since one of them uses the same key for snapshot and shuffle.
The better is to use KEY_CAMERA on all drivers solving this issue. This
follows the IR standard map as defined at:

The ir-keymaps.c has frequent additions. As people tend to copy an old
keyboard entry, a bad CodingStyle at an ancient entry may result on a
freshly bad CodingStyle patch.
So, better to fix the CodingStyle for the entire file.
This patch is the first of a series of patches fixing it, generated by
some perl magic plus manual handling.

A user discovered that the Geniatech x8000 encountered a regression when
the xc3028 power management was introduced. The xc3028 never recovers after
setting the powerdown register, which is probably because the xc3028 reset
GPIO is not properly configured. Since I do not have access to the hardware
and thus cannot determine the correct GPIO configuration, just disable xc3028
power management on this board, which fixes the regression.
Thanks to user "ritec" for reporting the issue and testing the fix.

Fixes stack corruption bug present in dump_regs function of zl10353 and
qt1010 drivers: the buffer buf was one byte smaller than required -
there are 4 chars for address prefix, 16 * 3 chars for dump of 16 eeprom
bytes per line and 1 byte for zero ending the string required, i.e. 53
bytes, but only 52 were provided.
The one byte missing in stack based buffer buf can cause stack
corruption possibly leading to kernel oops, as discovered originally

Change order data of buffer in FM simple_tune function. It is usefull for:
1. Set data of tuner with CP bit UP. 0xCE for MK5 or 0xC6 for MK3
2. When call simple_fm_tune, read this byte from config and overwrite
this byte in function simple_radio_bandswitch for set CP bit to OFF.
Of course it can be usefull for other tuner for overwrite default
settings of FM.

The only two countries that are known to use 6MHz bandwidth are Taiwan
and Uruguay. Both use QAM subcarriers at OFTM.
This patch fixes the firmware load for such countries, where the
required firmware is the QAM one.
This also confirms the previous tests where it was noticed that the 6MHz
QAM firmware doesn't work for cable. So, this patch also removes support
for DVB-C, instead of just printing a warning.

completion
Instead of polling at 100ms intervals for register writes, poll at 5ms
intervals. This is consistent with the xc5000 specification, and improves
tuning time by up to 500 ms on devices that such as the au0828 which do not
properly implement i2c clock stretching (since the five register writes that
occur for a tuning request often do not complete immediately but do complete
far before 100ms has gone by).
The net amount of time we wait before timing out is unchanged (500ms).

Bring back the code that puts the xc5000 to sleep. For the Pinnacle 801e
this results in power consumption at idle dropping from 325ma to 124ma.
If there are *actually* any devices that don't work in this configuration,
they should set dvb_frontend.ops.tuner_ops.sleep to NULL (per mkrufky's
suggestion)
Also, had to make sure we were making sure the firmware was loaded in the
