| | | | | | | | | | | | | | It appears that controls are ordered by ID number when enumerating. That could lead illogical UI as controls are usually enumerated and drawn by the application at runtime. Change order of controls by reorganizing assigned IDs now as we can.

* [media] v4l: add RF tuner channel bandwidth controlAntti Palosaari2014-03-132-0/+6
| | | | | | | | | | | | | | | | | | | 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.

* [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.
