In the past, T_STANDBY were used on devices with a separate radio tuner to mark a tuner that were disabled. With the time, it got newer meanings. Also, due to a bug at the logic, the driver might incorrectly return T_STANDBY to userspace. So, instead of keeping the abuse, just use a boolean for storing such information. We can't remove T_STANDBY yet, as this is used on two other drivers. A latter patch will address its usage outside tuner-core.

Properly document those functions and do some cleanups around that. There's just one behavior change on this patchset: it will now restore TV frequency when changing from radio to TV mode. Signed-off-by: -

This is a big patch with no functional changes. It just rearranges everything inside the driver, and prepares to break TV and Radio into two separate fops groups. Currently, it has an heuristics logic to determine if the call came from radio or video. However, the caller driver knows for sure, so tuner-core shouldn't try to guess it. Signed-off-by: -

After registering the cdev, it would be possible do have an open on it. In a matter of fact, some versions of udev do this. So, move registration to the end and protect it with a mutex. Signed-off-by: -

Some devices don't need to use it. So allow to just disable this logic. Having it enabled on some devices cause power management to complain, generating error -71. Signed-off-by: -

Instead of per-model tests all over the code, use some parameters at the board entries to describe the model variants for: - devices with 417 MPEG encoder; - devices that use external AV; - devices where vbi VANC endpoint doesn't work; - devices with xc5000 that require different IF initialization (and probably will cover also xc3028). - devices with xceive tuner that require a reset during init. Signed-off-by: -
Mauro Carvalho Chehab authored
The check for xc5000 assumes that the tuner will always be using the same bus and will have the same address. As those are configurable via dev->board, it should use, instead, the values defined there. Also, a similar type of test will be needed by other tuners (for example, for TUNER_XC2028) Signed-off-by: -

Just a cleanup patch. Removes one indent level by moving the return -ENODEV to happen before the device register logic, if the interface is not the audio/video (int 1). Signed-off-by: -

When a device is not detected, the driver prints a warning message. That's ok, except for the fact that, even on newer devices that have eeprom but aren't yet supported, it prints a message saying that the device doesn't have eeprom. Fix it by having a separate message for devices with eeprom, but not yet known by the driver. Signed-off-by: -

This driver is abusing the kernel<=>userspace API, due to the lack of a proper solution for it. A discussion were done at: http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html But there's not a solution for it yet. So, move the driver to staging, while we don't have a final solution. Signed-off-by:
