Bits EXYNOS4_DEC_MODE and EXYNOS4_ENC_MODE do not get cleared on software reset. These bits need to be cleared explicitly. Even though the bits in question are already cleared in interrupt service routine, the reset should also clear them in case when e.g. bootloader uses the codec and leaves it in a bad state.

Clearing the bits turns off the encoder/decoder. If the hardware is not turned off after use, at subsequent uses it does not work in a stable manner, resulting in incorrect interrupt status value being read and e.g. erroneous read of compressed bitstream size. Signed-off-by:

In case of corrupt images, multiple interrupts may occur due to different error scenarios. Since we are removing the src and dest buffers in the first interrupt itself, crash occurs in the second error interrupts. Disable the global interrupt before we start processing the interrupt to avoid the crash. Disable System interrupt in isr to avoid the crash below.

Originally the "size" member was modified in a local variable passed to s5p_jpeg_parse_hdr() but the member was not used by the caller, so it did not matter. After applying patch "media: s5p-jpeg: Don't use temporary structure in s5p_jpeg_buf_queue" the unnecessary assignment started overwriting already assigned "size" member of the passed structure with an incorrect value.

This enables MaxS4/S8 and Octopus Max card support in ddbridge by adding glue code into ddbridge-core, having another PCI ID, and have the LNB IC control code (and all other MaxS4/8 related code) in ddbridge-maxs8.c (rather than another ~400 LoC in ddbridge-core.c like it's done in the original vendor driver package).

This adds the frontend driver for the MaxLinear MxL5xx family of tuner- demodulators, as used on Digital Devices MaxS4/8 four/eight-tuner cards. The driver was picked from the dddvb vendor driver package and - judging solely from the diff - has undergone a 100% rework: - Silly #define's used to pass multiple values to functions were expanded. This resulted in macro/register names not being usable anymore for such occurences, but makes the code WAY more read-, understand- and maintainable. - CamelCase was changed to kernel_case - All typedef were removed - Overall code style was fixed, besides >80char lines in _defs.h and _regs.h, checkpatch is happy. - Also, signal stat acquisition was made to comply with the DVB API ways to do these things. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>. Signed-off-by:

This implements the diseqc_send_burst frontend op to support sending mini-DISEQC bursts. Picked up from dddvb's driver package where this specific block was disabled via #if 0/#endif, but is still working according to feedback from upstream, so add it. Signed-off-by:

According to the documentation, FE_SCALE_DECIBEL values should be assigned to .svalue and not .uvalue, so let's do this. While at it, remove the unneeded strength var from read_signal_strength(). Signed-off-by:
