Not sure why, but, on ia64, with Linaro's gcc 7.3 compiler, using #ifdef (CONFIG_I2C) is not OK. So, replace it by IS_ENABLED(CONFIG_I2C), in order to fix the builds there. Reported-by:

Hauppauge produced a revision of ImpactVCBe using an 888, with a 25MHz crystal, instead of using the default third overtone 50Mhz crystal. This overrides that frequency so that the cx25840 is properly configured. Without the proper crystal setup the cx25840 cannot load the firmware or decode video. Signed-off-by:

Currently clk_freq is ignored entirely, because the cx235840 driver configures the xtal at the chip defaults. This is an issue if a board is produced with a non-default frequency crystal. If clk_freq is not zero the cx25840 will attempt to use the setting provided, or fall back to defaults otherwise. Signed-off-by:

Proper cx2388x chip type is detected in cx25840 probe, the clock rate is untouched however in probe. The cx25840 only checks for non default clock values for 888 and provides custom settings for 25MHz 888. This change ensures that cx23888 chips with default 50MHz crystals will not get configured as if they have 25MHz crystals. A cx23887 board will continue to be configured for 25MHz crystal as there is no custom clock support included for it. Signed-off-by:

The cx25840 driver currently configures 885, 887, and 888 using default divisors for each chip. This check to see if the cx23885 driver has passed the cx25840 a non-default clock rate for a specific chip. If a cx23885 board has left clk_freq at 0, the clock default values will be used to configure the PLLs. This patch only has effect on 888 boards who set clk_freq to 25M. Signed-off-by:

A possible hardware bug was discovered when using CA addon hardware attached to the ngene hardware, in that the TS input buffer much likely will shift and thus become unaligned to 188 byte blocks (a full TS frame) when things like CA module initialisation (which happens via differing communication paths) take place. This causes the TS NULL removal in tsin_exchange() to fail to detect this previously inserted data and thus causes userspace applications to receive data they didn't sent beforehand and ultimately cause troubles. On driver load with an inserted CAM, buffers are fine at first (note that the driver has to keep the communication running from/to the card by inserting TS NULL frames, this is done in tsout_exchange() via FillTSBuffer() - that data is simply sent back by the hardware): offset | 0 1 2 3 4 5 .... 188 189 190 191 192 193 .... 376 data | 47 1f ff 10 6f 6f .... 47 1f ff 10 6f 6f .... 47 After a few seconds, the CA module is recognised and initialised, which is signalled by dvb_ca_en50221: dvb_ca adapter X: DVB CAM detected and initialised successfully This is where the first shift happens (this is always four bytes), buffer becomes like this: offset | 0 1 2 3 4 5 .... 188 189 190 191 192 193 .... 376 data | 6f 6f 6f 6f 47 1f .... 6f 6f 6f 6f 47 1f .... 6f Next, VDR, TVHeadend or any other CI aware application is started, buffers will shift by even more bytes. It is believed this is due to the hardware not handling control and data bytes properly distinct, and control data having an influence on the actual data stream, which we cannot properly detect at the driver level. Workaround this hardware quirk by adding a detection for the TS sync byte 0x47 before each TS frame copy, scan for a new SYNC byte and a TS NULL packet if buffers become unaligned, take note of that offset and apply that when copying data to the DVB ring buffers. The last <188 bytes from the hardware buffers are stored in a temp buffer (tsin_buffer), for which the remainder will be in the beginning of the next hardware buffer (next iteration of tsin_exchange()). That remainder will be appended to the temp buffer and finally sent to the DVB ring buffer. The resulting TS stream is perfectly fine, and the TS NULL packets inserted by the driver which are sent back are properly removed. The resulting offset is being clamped to 188 byte segments (one TS packet). Though this can result in a repeated TS packet if the overall offset grows beyond this (and it will grow only on CA initialisation), this is still way better than unaligned TS frames and data sent to userspace that just isn't supposed to be there. This compensation can be toggled by the ci_tsfix modparam, which defaults to 1 (enabled). In the case of problems, this can be turned off by setting the parameter to 0 to restore the old behaviour.

Move the copy logic that will skip previously inserted TS NULL frames when moving data to the DVB ring buffers into an own function. This is done to not duplicate code all over the place with the following TS offset shift fixup patch. While we're touching this part of the code, get rid of the DEBUG_CI_XFER debug-ifdeffery. This could be toggleable either by a Kconfig or a module param, but in the end this will accidentally be enabled and cause lots of kernel log messages, and such devel debug shouldn't be there anyway.

On some architectures such as arm64, siano chip based TV-tuner USB devices are not recognized correctly due to coherent memory allocation failure with the following error: [ 663.556135] usbcore: deregistering interface driver smsusb [ 683.624809] smsusb:smsusb_probe: board id=18, interface number 0 [ 683.633530] smsusb:smsusb_init_device: smscore_register_device(...) failed, rc -12 [ 683.641501] smsusb:smsusb_probe: Device initialized with return code -12 [ 683.652978] smsusb: probe of 1-1:1.0 failed with error -12 This is caused by dma_alloc_coherent(NULL, ...) returning NULL in smscoreapi.c. To fix this error, allocate the buffer memory for the USB devices via kmalloc() and let the USB core do the DMA mapping and free. Signed-off-by:

Links like :ref:`VIDIOC_STREAMON` expand to "ioctl VIDIOC_STREAMON, VIDIOC_STREAMOFF". Thus our reader will think we are talking about STREAMON _and_ STREAMOFF, but only one of the two actually applies in some cases. Fix by adding a link title, so the reader will read only the correct ioctl name. Signed-off-by:
