There are several bugs at the signal strength algorithm: - It is using logical OR, instead of bit OR; - It doesn't wait up to 18 ms as it should; - the strength range is not ok. Rework on it, in order to make it work. Signed-off-by:Mauro Carvalho Chehab <mchehab@redhat.com>

If g_tuner is called and the tuner is able to return the signal strength via has_signal(), call the tunner callback to retrieve such data for all tuner types, not only for radio ones. Signed-off-by:

Change the firmware logic to use request_firmware_nowait(), and to preserve the loaded firmwares in memory, to reduce the risk of troubles with buggy userspace apps. With this change, while the firmware is being loaded, the driver will return -EAGAIN to any calls. If, for some reason, firmware failed to be loaded from userspace, it will return -ENODEV.

If firmware is not loaded for some reason, or if it is not ready yet, it makes no sense to honour to any DVB callbacks. So, return -EAGAIN, as the error condition may be temporary. If the device doesn't initialize, either because it requires a firmware or because there's an error during init_drxk, returns -ENODEV, to indicate such error, on all DVB callbacks. Signed-off-by: -

As it will be using the unlocked version of i2c_transfer during firmware loads, make sure that the priv state routine will be used on all I2C calls, in preparation for the next patch that will implement an exclusive lock mode to be used during firmware load, at drxk_init. Signed-off-by: -

The firmware blob may not be available when the driver probes. Instead of blocking the whole kernel use request_firmware_nowait() and continue without firmware. This shouldn't be that bad on drx-k devices, as they all seem to have an internal firmware. So, only the firmware update will take a little longer to happen. Signed-off-by: -

Some drivers (in particular for TV cards) need exclusive access to their I2C buses for specific operations. Export an unlocked flavor of i2c_transfer to give them full control. The unlocked flavor has the following limitations: * Obviously, caller must hold the i2c adapter lock. * No debug messages are logged. We don't want to log messages while holding a rt_mutex. * No check is done on the existence of adap->algo->master_xfer. It is thus the caller's responsibility to ensure that the function is OK to call. Signed-off-by:

This is basically s/getmode/getrxsubchans/ and s/setmode/setaudmode/ with some whitespace adjustment in affected lines to please the eye. The rename is done to point out their relation to the rxsubchans and audmode fields of struct v4l2_tuner. I also corrected a commented out call to v4l_dbg in one of the lines. Signed-off-by:

The windows driver used different values for the GPIOs and analog decoder configuration. The values from the windows driver are now used. It also seems that the windows driver has LNA always disabled. Thus we are doing the same (using the same flags as on windows). I (only) tested with DVB-T and it worked quite well.
