That RF tuner driver is bound via SPI bus model and it implements V4L subdev API. I split it out from MSi3101 SDR driver. MSi3101 = MSi2500 + MSi001. Signed-off-by:

Add volatile boolean control to indicate if tuner frequency synthesizer is locked to requested frequency. That means tuner is able to receive given frequency. Control is named as "PLL lock", since frequency synthesizers are based of phase-locked-loop. Maybe more general name could be wise still? Cc: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by:

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. It is not reasonable possible after the API is released. Also, leave some spare space between IDs too for possible future extensions. Cc: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by:

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. Cc: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by:

It was possible that tuner_frequency variable, used for carrier offset compensation, was uninitialized. That happens when tuner .get_frequency() callback is not defined. Currently that case is not possible as only used tuner has this callback. Coverity CID 1166057: Uninitialized scalar variable (UNINIT) Signed-off-by:

While playing with make coccicheck I noticed this message: drivers/media/rc/rc-main.c:1245:3-9: preceding lock on line 1238 It was introduced by commit 587d1b06 ([media] rc-core: reuse device numbers) which returns -ENOMEM after a mutex_lock without first unlocking it when there are no more device numbers left. The added code doesn't depend on the device lock, so move it before the lock is taken. Signed-off-by:

Static checkers complain about the inconsistent NULL check here. 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.

ARRAY_SIZE(buf) (8 elements) was intended instead of sizeof(buf) (16 bytes). But this is just a sanity check and the callers always pass valid values so this doesn't cause a problem. Signed-off-by:

Add remote control input driver for the ImgTec Infrared block hardware decoder, which is set up with timings for a specific protocol and supports mask/value filtering and wake events. The hardware decoder timing values, raw data to scan code conversion function and scan code filter to raw data filter conversion function will be provided in separate files for each protocol which this part of the driver can use. The new generic scan code filter interface is made use of to reduce interrupts and control wake events. Signed-off-by:

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.
