The FE_SUPPORTED() macro is basically the same as IS_REACHABLE, except that it causes a warning with gcc-7: common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined] common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined] common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined] Using IS_REACHABLE() to define it avoids the warning.

changeset da8ec560 ("[media] ivtv: implement new decoder command ioctls") implemented proper support for mpeg audio and video control at V4L2 API. Since then, the usage of the the DVB APIs is deprecated. However, we never actually marked it as deprecated nor provided any way to disable it. Let's do it now. This patch prepares for the removal of this bad usage on a couple of Kernel versions. Fixes: da8ec560 ("[media] ivtv: implement new decoder command ioctls") Acked-by:

Remove unused demod driver. Device that used it never went public. If someone later decide to add support for a device using this chipset, it should be easy enough to retrieve it from git history. Signed-off-by:

I saw from ZyDAS ZD1301 sniffs it sets chip sleeping by using REG_MISC_CTRL. That has very huge effect for power management, around 0.9W. Sleep is still disabled for all the old hardware just to avoid possible regression as meaning of register bits are unknown. I tested it also with some other devices and it seems to be working, but I still consider it to be too risky to change it default. Signed-off-by:

ZyDAS ZD1301 is chip having USB interface and DVB-T demodulator integrated. This driver is for demodulator part. Driver is very reduced, just basic demodulator functionality, no statistics at all. It registers as a platform driver to driver core. Signed-off-by:

As reported by gcc: drivers/media/platform/sti/hva/hva-v4l2.c:227:6: warning: no previous prototype for 'hva_dbg_summary' [-Wmissing-prototypes] void hva_dbg_summary(struct hva_ctx *ctx) ^~~~~~~~~~~~~~~ This function is used only internally, so make it static. Signed-off-by: -
Jean-Christophe Trotin authored
This patch creates 4 static debugfs entries to dump: - the device-related information ("st-hva/device") - the list of registered encoders ("st-hva/encoders") - the current values of the hva registers ("st-hva/regs") - the information about the last closed instance ("st-hva/last") It also creates dynamically a debugfs entry for each opened instance, ("st-hva/<instance identifier>") to dump: - the information about the frame (format, resolution) - the information about the stream (format, profile, level, resolution) - the control parameters (bitrate mode, framerate, GOP size...) - the potential (system, encoding...) errors - the performance information about the encoding (HW processing duration, average bitrate, average framerate...) Each time a running instance is closed, its context (including the debug information) is saved to feed, on demand, the last closed instance debugfs entry.

ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. Fix up the 25ms delays here to use msleep() and reduce the load on the hrtimer subsystem. Link: http://lkml.org/lkml/2017/1/11/377Reviwed-by:
