* [media] v4l: add RF tuner channel bandwidth controlAntti Palosaari2014-03-131-0/+4
| | | | | | | | | | | | | | | | | | | Modern silicon RF tuners has one or more adjustable filters on signal path, in order to filter noise from desired radio channel. Add channel bandwidth control to tell the driver which is radio channel width we want receive. Filters could be then adjusted by the driver or hardware, using RF frequency and channel bandwidth as a base of filter calculations. On automatic mode (normal mode), bandwidth is calculated from sampling rate or tuning info got from userspace. That new control gives possibility to set manual mode and let user have more control for filters.

| | | | | | | | | | | | | It was possible that tuner_frequency variable, used for carrier offset compensation, was uninitialized. That happens when tuner .get_frequency() callback is not defined.

There is an unchecked dereference of "input->fe" in the call to tuner_attach_tda18271() and there is a second unchecked dereference a couple lines later when we do: input->fe2->tuner_priv = input->fe->tuner_priv; But actually "intput->fe" can't be NULL because if demod_attach_drxk() fails to allocate it, then we would have return an error code.

* [media] rc-main: automatically refresh filter on protocol changeJames Hogan2014-03-111-2/+39
| | | | | | | | | | | | | | | | | | | | | | | When either of the normal or wakeup filter protocols are changed, refresh the corresponding scancode filter, i.e. try and set the same scancode filter with the new protocol. If that fails clear the filter instead. If no protocol was selected the filter is just cleared, and if no s_filter callback exists the filter is left unmodified. Similarly clear the filter mask when the filter is set if no protocol is currently selected. This simplifies driver code which no longer has to explicitly worry about modifying the filter on a protocol change. This also allows the change_wakeup_protocol callback to be omitted entirely if there is only a single available wakeup protocol at a time, since selecting no protocol will automatically clear the wakeup filter, disabling wakeup.

| | | | | | | | | | | | | | | | | | Only a single allowed and enabled protocol mask currently exists in struct rc_dev, however to support a separate wakeup filter protocol two of each are needed, ideally as an array. Therefore make both rc_dev::allowed_protos and rc_dev::enabled_protocols arrays, update all users to reference the first element (RC_FILTER_NORMAL), and add a couple more helper functions for drivers to use for setting the allowed and enabled wakeup protocols. We also rename allowed_protos to allowed_protocols while we're at it, which is more consistent with enabled_protocols.
