The get_state()/set_state and the corresponding data types (struct tuner_state and enum tuner_param) are old DVB interfaces that came from the DVBv3 time. Nowadays, set_params() provide a better way to set the tuner and demod parameters. So, no need to keep those legacy stuff, as all drivers that were using it got converted. With this patch, all kABI elements at dvb_frontend.h are now documented. Signed-off-by: NMauro Carvalho Chehab <mchehab@osg.samsung.com>

There are several tuner_param values that aren't by any driver or core: DVBFE_TUNER_TUNERSTEP DVBFE_TUNER_IFFREQ DVBFE_TUNER_REFCLOCK DVBFE_TUNER_IQSENSE DVBFE_TUNER_DUMMY Several of those correspond to the values at the tuner_state struct with is also only initialized by not used anyware: u32 tunerstep; u32 ifreq; u32 refclock; It doesn't make sense to keep anything at the kABI that it is not used. So, get rid of them. Signed-off-by: NMauro Carvalho Chehab <mchehab@osg.samsung.com>

This function is used mainly at the DVB core, in order to provide emulation for a legacy ioctl.

struct timeval uses a 32-bit seconds representation which will overflow in the year 2038 and beyond. This patch replaces the usage of struct timeval with ktime_t which is a 64-bit timestamp and is year 2038 safe. This patch is part of a larger attempt to remove all instances of 32-bit timekeeping variables (timeval, timespec, time_t) which are not year 2038 safe, from the kernel.

The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

While several tuners have some sort of suspend/resume implementation, this is currently mangled with an optional .sleep callback that it is also used to put the device on low power mode. Not all drivers implement it, as returning the driver from low power may require to re-load the firmware, with takes some time. Also, some drivers may delay it. So, the more coherent is to add two new optional callbacks that will let the tuners to directy implement suspend and resume callbacks if they need.

Some fe drivers will have to do additional initialization in their fe ops.init interfaces when called during resume. Without the additional initialization, fe and tuner driver resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME is necessary to detect resume case. This patch adds a new define and changes dvb_frontend_resume() to set it prior to calling fe init and tuner init calls and resets it back to DVB_FE_NO_EXIT once fe and tuner init is done.

Some fe drivers attempt to access the device for power control from their release routines. When release routines are called after device is disconnected, the attempts fail. fe drivers should avoid accessing the device, from their release interfaces when called from disconnect path. dvb-frontend maintains exit flag to keep track when fe device is disconnected in its private data structures. Export the flag in fe to enable drivers to check the device status from their release interfaces.

The get_rf_strength op in tuner-simple is valid only for the radio mode. But due to the way get_signal in analog_demod_ops was designed it would overwrite the signal value with a bogus value when in TV mode. Pass a pointer to the signal value instead, and when not in radio mode leave it alone in the tuner-simple. This broke in commit 030755bd (tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before that this was working correctly. That commit did the right thing, but what wasn't realized at the time was that tuner-simple should have been updated as well to restrict setting the signal strength to the radio mode only.

Add the logic to poll, reset counters and report the QoS stats to the end user. The idea is that the core will periodically poll the frontend for the stats. The frontend may return -EBUSY, if the previous collect didn't finish, or it may fill the cached data. The value returned to the end user is always the cached data.

Just like set_frontend, use the dvb cache properties for get_frontend. This is more consistent, as both functions are now symetric. Also, at the places get_frontend is called, it makes sense to update the cache. Most of this patch were generated by this small perl script: while (<>) { $file .= $_; } if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) { my $get = $1; $file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g; } print $file; Of course, the changes at dvb_frontend.[ch] were made by hand, as well as the changes on a few other places, where get_frontend() is called internally inside the driver. On some places, get_frontend() were just a void function. Those occurrences were removed, as the DVB core handles such cases. Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>
