From: Mauro Carvalho Chehab <mchehab@redhat.com>
changeset 4ecae6da8244 removed algo_control from i2c drivers. However,
on older kernels, a dummy function to implement algo_control is required,
otherwise, an OOPS is generated.
This patch adds a backport for all i2c drivers that defines an
i2c_algorithm, except for cafe_ccic, since OLPC hardware only works
for kernels newer than 2.6.19.
Some of the backported drivers would need also extra changes to work with
older kernels, as specified on v4l/versions.txt. Yet, I decided to add
the backport for those drivers also, since the lack of algo_control doesn't
generate any compilation error, but it is enough to break the driver. So,
better to all for all boards than to allow compiling a kernel backported that
just generates OOPS.
Priority: normal

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.
Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.
options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.
With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

This patch removes all static dependencies on the dvb-pll module.
All exported dvb_pll_desc's have been UNexported, and the caller
will reference the individual dvb_pll_desc by it's index in the
pll_list array.

The last user of dvb_pll_configure was the dvb-usb function
dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around
dvb_pll_configure(). It's just a copy of the functionality provided by
the tuner_ops calc_regs method, and can be deleted.
There were two users of dvb_usb_tuner_calc_regs().
One was dvb_usb_tuner_set_params_i2c(), which is converted to use
fe->ops.tuner_ops.calc_regs().
The other was the digitv driver. This driver can use one of two demods,
mt352 or nxt6000. For the mt352, the driver would set
tuner_ops.calc_regs to dvb_usb_tuner_calc_regs(). We can just attach
dvb_pll and use the tuner_ops.calc_regs() provided by that module.
For the nxt600, the driver would set tuner_ops.set_params to
digitv_nxt6000_tuner_set_params. That function would in turn use
dvb_usb_tuner_calc_regs(). We convert it to use tuner_ops.calc_regs()
instead, and use dvb_pll_attach.
The digitv_tuner_attach() needs to know which frontend was attached by
digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params()
to be overridden with digitv_nxt6000_tuner_set_params(). So to do this a
digitv_state that says which frontend was used is added to the
dvb_usb_device private state field.

dvb-pll normally opens the i2c gate before attempting to communicate with
the pll, but the code for this device is not using dvb-pll. This should
be cleaned up in the future, but for now, just open the i2c gate at the
appropriate place in order to fix this driver bug.

Multi-input patch for DVB-USB device
From: Patrick Boettcher <pb@linuxtv.org>
This patch is the first commit of the Multiple Input Patch for the DVB-USB frame
work.
It changes the DVB-USB-device to be able to have more than one streaming input
(e.g. multiple DVB-T sources) on one device. This is a necessary feature for
the upcoming DiB7700 driven devices.

dvb_frontend
From: Patrick Boettcher <pb@linuxtv.org>
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
always, before you could assign the static pointer directly, which was
dangerous.

When a firmware was downloaded dvb_usb_device_init returns NULL for the dvb_usb_device,
then nothing should be done with that pointer and device, because it will re-enumerate.
A new firmware should be used with digitv devices. It should make "slave"-devices work and others, too.

The name member of the i2c_algorithm is never used, although all
drivers conscientiously fill it. We can drop it completely, this
structure doesn't need to have a name.
[PATCH] I2C: Kill i2c_algorithm.id (4/7)
There are no more users of i2c_algorithm.id, so we can finally drop
this structure member.
[PATCH] I2C: Kill i2c_algorithm.id (6/7)
In theory, there should be no more users of I2C_ALGO_* at this point.
However, it happens that several drivers were using I2C_ALGO_* for
adapter ids, so we need to correct these before we can get rid of all
the I2C_ALGO_* definitions.
Note that this also fixes a bug in media/video/tvaudio.c:
/* don't attach on saa7146 based cards,
because dedicated drivers are used */
if ((adap->id & I2C_ALGO_SAA7146))
return 0;
This test was plain broken, as it would succeed for many more adapters
than just the saa7146: any those id would share at least one bit with
the saa7146 id. We are really lucky that the few other adapters we want
this driver to work with did not fulfill that condition.
