Some users have been having a hard time finding the hidden
menus. A typically case are camera sensor drivers
(e.g IMX219, OV5645, etc), which are common on embedded
platforms and not really "ancillary" devices.
The problem with MEDIA_SUBDRV_AUTOSELECT seems to be related
to the fact that it uses the "visible" syntax to hide
the menus.
This is not obvious and it normally takes some time to
figure out.
To fix the problem, add a comment on each of hidden menus,
which should clarify what option is causing menus to be hidden.

Embedded systems often connect to sensors or other multimedia
subdevices directly. Currently, to be able to select such a
subdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto-
select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT).
This is inconvenient as the ancillary drivers for a particular
device then need to be selected manually.
Allow to select drivers manually while keeping the auto-select
feature in case EXPERT (selected by EMBEDDED) is enabled.

This patch adds driver for mxl301rf OFDM tuner chips.
It is used as an ISDB-T tuner in earthsoft pt3 cards.
Note that this driver does not initilize the chip,
because the initilization sequence / register setting is not disclosed.
Thus, the driver assumes that the chips are initilized externally
by its parent board driver before tuner_ops->init() are called,
like in PT3 driver where the bridge chip contains the init sequence
in its private memory and provides a command to trigger the sequence.

This is happening because a builtin module can't use directly a symbol
found on a module. By enabling CONFIG_MEDIA_ATTACH, the configuration
becomes valid, as dvb_attach() macro loads the module if needed, making
the symbol available to the builtin module.
While this bug started to appear after the patches that use IS_DEFINED
macro (like changeset 7b34be71db), this
bug is a way ancient than that.
The thing is that, before the IS_DEFINED() patches, the logic used to be:
&& defined(MODULE))
struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
u8 i2c_addr,
struct i2c_adapter *i2c);
static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
u8 i2c_addr,
struct i2c_adapter *i2c)
{
printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__);
return NULL;
}
The above code, with the .config file used, was evoluting to FALSE
(instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'),
and were adding the static inline code at saa7134-dvb, instead
of the external call. So, while it weren't producing any compilation
error, the code weren't working either.
So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just
enable it, if MODULES is defined.

This driver was written from scratch, based on an existing driver
that it is part of rtl-sdr git tree, released under GPLv2:
https://groups.google.com/forum/#!topic/ultra-cheap-sdr/Y3rBEOFtHughttps://github.com/n1gp/gr-bazhttp://cgit.osmocom.org/rtl-sdr/plain/src/tuner_r820t.c
(there are also other variants of it out there)
>From what I understood from the threads, the original driver was converted
to userspace from a Realtek tree. I couldn't find the original tree.
However, the original driver look awkward on my eyes. So, I decided to
write a new version from it from the scratch, while trying to reproduce
everything found there.
TODO:
- After locking, the original driver seems to have some routines to
improve reception. This was not implemented here yet.
- RF Gain set/get is not implemented.

Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.
That simplifies the life for users, as they can just keep
this untouched.
Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.
