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:

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:

Commit a006c04e ("[media] exynos-gsc: Fixup clock management at ->remove()") changed the driver's .remove function logic to fist do a pm_runtime_get_sync() to make sure the device is powered before attempting to gate the gsc clock. But the commit also removed a pm_runtime_disable() call that leads to an unbalanced pm_runtime_enable() error if the driver is removed and re-probed: exynos-gsc 13e00000.video-scaler: Unbalanced pm_runtime_enable! exynos-gsc 13e10000.video-scaler: Unbalanced pm_runtime_enable!

The VDOA is able to transform the NV12 custom macroblock tiled format of the CODA to YUYV format. If and only if the VDOA is available, the driver can also provide YUYV support. While the driver is configured to produce YUYV output, the CODA must be configured to produce NV12 macroblock tiled frames and the VDOA must transform the intermediate result into the final YUYV output.

If the CODA driver is configured to produce NV12 output and the VDOA is available, the VDOA can be used to transform the custom macroblock tiled format to a raster-ordered format for scanout. In this case, set the output format of the CODA to the custom macroblock tiled format, disable the rotator, and use the VDOA to write to the v4l2 buffer. The VDOA is synchronized with the CODA to always un-tile the frame that the CODA finished in the previous run. Signed-off-by:
