Commit e7890297 ("i2c: sh_mobile: don't send a stop condition by default inside transfers") makes the i2c_sh_mobile I2C-adapter emit a stop/start sequence between messages in a single transfer only when explicitly requested with I2C_M_STOP. This breaks the ov772x driver in the SH4 Migo-R board as the Omnivision sensor uses the I2C-like SCCB protocol that doesn't support repeated starts: i2c-sh_mobile i2c-sh_mobile.0: Transfer request timed out ov772x 0-0021: Product ID error 92:92 Fix it by marking the client as SCCB, forcing the emission of a stop/start sequence between all messages. As I2C_M_STOP requires the I2C adapter to support protocol mangling, ensure that the I2C_FUNC_PROTOCOL_MANGLING functionality is available. Tested on SH4 Migo-R board, with OV772x now successfully probing soc-camera-pdrv soc-camera-pdrv.0: Probing soc-camera-pdrv.0 ov772x 0-0021: ov7725 Product ID 77:21 Manufacturer ID 7f:a2 Signed-off-by:

Since 2015, the documentation for FE_DISEQC_SEND_BURST, FE_SET_TONE and FE_SET_VOLTAGE are incorrectly saying that the enums are passed by reference. They aren't: they're passed by value. Fix the documentation to reflect reality. Fixes: 81959d99 ("[media] DocBook: better document FE_DISEQC_SEND_BURST ioctl") Fixes: d6b6d346 ("[media] DocBook: better document FE_SET_VOLTAGE ioctl") Fixes: 6dc59e7a ("[media] DocBook: better document FE_SET_TONE ioctl") Reported-by:

'struct video_event' is used for the VIDEO_GET_EVENT ioctl, implemented by drivers/media/pci/ivtv/ivtv-ioctl.c and drivers/media/pci/ttpci/av7110_av.c. The structure contains a 'time_t', which will be redefined in the future to be 64-bit wide, causing an incompatible ABI change for this ioctl. As it turns out, neither of the drivers currently sets the timestamp field, and it is presumably useless anyway because of the limited resolutions (no sub-second times). This means we can simply change the structure definition to use a 'long' instead of 'time_t' and remain compatible with all existing user space binaries when time_t gets changed. If anybody ever starts using this field, they have to make sure not to use 1970 based seconds in there, as those overflow in 2038. Signed-off-by:

We want all media drivers to build with COMPILE_TEST, as the Coverity instance we use on Kernel works only for x86. Also, our test workflow relies on it, in order to identify git bisect breakages. Signed-off-by:

Properly detect and attach Ports and Flex modules with the Sony CXD28xxER series demods. This makes newer Cine cards and most DuoFlex C/C2/T/T2 (or any combination of these systems) work, PCI IDs need to be added though. Note: This utilises the CXD2841ER demod driver, which requires the changes from this patch series to properly work. Without those changes, it won't function properly (if at all). Signed-off-by:

Some Flex modules (mostly with anyof C/C2/T/T2 demods based on the Sony CXD28xxER series) are equipped with an interface named XO2 (which appears to be the Lattice MachXO2). Add functionality to detect such links and initialise them, so any tuner module with such an interface can be used. This also adds dummy detection for any possible connected module, telling the user it isn't supported at this very moment. Also adds i2c_io(), i2c_write() and i2c_write_reg(), all required for the XO2 handling functionality. Signed-off-by:

This is a backport of the board control setup from the vendor provided dddvb driver package, which does additional device initialisation based on the board_control device info values. Also backports the TS quirk flags which is used to control setup and usage of the tuner modules soldered on the bridge cards (e.g. CineCTv7, CineS2 V7, MaxA8 and the likes). Functionality originates from ddbridge vendor driver. Permission for reuse and kernel inclusion was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.

On DVB-T/T2 at least, SNR might be reported as >2500dB, which not only is just wrong but also ridiculous, so fix this by improving the conversion of the register value. The INTLOG10X100 function/macro and the way the values are converted were both taken from DD's cxd2843 driver. Signed-off-by:

Don't wait for FE_HAS_LOCK in set_frontend_tc() and thus don't hammer the lock status register with inquiries when CXD2841ER_NO_WAIT_LOCK is set in the configuration, which also unneccessarily blocks applications until a TS LOCK has been acquired. Rather, API and applications will check for a TS LOCK by utilising the tune fe_op, read_status and get_frontend ops, which is sufficient. Signed-off-by:

When AUTO_IFHZ is set and the tuner is supposed to provide proper IF speed values, it should be possible to have the tuner setup take place before the demod is configured, else the demod might be configured with either wrong (old), or even no values at all, which obviously will cause issues. To set this behaviour in the most flexible way, this is done with a separate flag instead of making this depend on AUTO_IFHZ. It should be evaluated if tuning shouldn't take place earlier in all cases and hardware constellations. Signed-off-by:

Add a AUTO_IFHZ flag and a function that will read IF speed values from any attached tuner if the tuner supports this and if AUTO_IFHZ is enabled, and else the passed default value (which probably matches Sony ASCOT tuners) will be passed back. The returned value is then used to calculate the iffeq which the demod will be programmed with. Signed-off-by:

Some cards/bridges wrap i2c_gate_ctrl handling with a mutex_lock(). This is e.g. done in ddbridge to protect against concurrent tuner access with regards to the dual tuner HW, where concurrent tuner reconfiguration can result in tuning fails or bad reception quality. When the tuner driver additionally tries to open the I2C gate (which e.g. the tda18212 driver does) when the demod already did this, this will lead to a deadlock. This makes the calls to i2c_gatectrl from the demod driver optional when the flag is set, leaving this to the tuner driver. For readability reasons and to not have the check duplicated multiple times, the setup is factored into cxd2841er_tuner_set(). This commit also updates the netup card driver (which seems to be the only consumer of the cxd2841er as of now). Signed-off-by:

Throughout the patch series some configuration flags will be added to the demod driver. This patch prepares this by adding the flags var to struct cxd2841er_config, which will serve as a bitmask to toggle various options and behaviour in the driver. Signed-off-by:

The way the MAKE_IFFREQ_CONFIG macros are written make it impossible to pass regular integers for iffreq calculation, since this will cause "SSE register return with SSE disabled" compile errors. This changes the calculation into C functions which also might help when debugging. Also, expand all passed frequencies from MHz to Hz scale. Signed-off-by:
