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.

James Hogan authored
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.

Add a wakeup_protocols sysfs file which controls the new rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of protocols that are used for the wakeup filter. A new RC driver callback change_wakeup_protocol() is called to change the wakeup protocol mask. Signed-off-by:

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. Signed-off-by:

The allowed and enabled protocol masks need to be expanded to be per filter type in order to support wakeup filter protocol selection. To ease that process abstract access to the rc_dev::allowed_protos and rc_dev::enabled_protocols members with inline functions. Signed-off-by:

James Hogan authored
Add generic scancode filtering of RC input events, and fall back to permitting any RC_FILTER_NORMAL scancode filter to be set if no s_filter callback exists. This allows raw IR decoder events to be filtered, and potentially allows hardware decoders to set looser filters and rely on generic code to filter out the corner cases. Signed-off-by:

On certain motherboards (mainly Intel NUC series) bios keeps the Nuvoton CIR device disabled at boot. This patch adds a call to kernel PNP layer to activate the device if it is not already activated.

DViCO FusionHDTV7 device that use au0828 can fail to communicate with xc5000 using i2c interface because of high i2c clock speed - i2c clock stretching bug. It causes to fail xc5000 firmware loading normally at the current driver. Already this problem fixed as changing to low i2c clock speed at HVR-950q device, also DViCO FusionHDTV7 device can solve it as using low i2c clock speed - 20KHz. Signed-off-by:

Propagate errors returned by drivers from the s_filter callback back to userland when updating scancode filters. This allows userland to see when the filter couldn't be updated, usually because it's not a valid filter for the hardware. Previously the filter was being updated conditionally on success of s_filter, but the write always reported success back to userland. Reported-by:
