drivers/media/i2c/tc358743.c:148:19: warning: Variable length array is used. As the maximum size is 1026, we can't use dynamic var, as it would otherwise spend 1056 bytes of the stack at i2c_wr() function. So, allocate a buffer with the allowed maximum size together with the state var. Signed-off-by:

While this is the first DVB platform drivers, let's keep the Kconfig options well organized, adding it on its own DVB menu. Of course, it should depend on MEDIA_DIGITAL_TV_SUPPORT, as this enables all DVB-related menus. Signed-off-by: -

The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added. Signed-off-by:

As reported by smatch: drivers/media/platform/sti/c8sectpfe/c8sectpfe-core.c:365 find_channel() error: buffer overflow 'fei->channel_data' 8 <= 63 It seems that a cut-and-paste type of error occurred here: the channel_data array size is C8SECTPFE_MAX_TSIN_CHAN, and not C8SECTPFE_MAXCHANNEL.

This patch adds support for the following 2 NIM cards: - 1) B2100A (2x stv0367 demods & 2x NXP tda18212 tuners) 2) STV0903-6110NIM (stv0903 demod + 6110 tuner, lnb24) A NIM card is a cold plugable expansion card which usually features a demodulator / tuner combination. Signed-off-by:

These functions are used by the core code for creating the LDVB devices and adapter. Addtionally some older SoC's (and potentially newer ones) have different frontend HW which would allow those devices to be easily supported in the future by keeping the code specific to the IP separate from the more generic code.

This patch adds support for the c8sectpfe input HW found on STiH407/410 SoC's. It currently supports the TS input block, memdma engine and hw PID filtering blocks of the C8SECTPFE subsystem. The driver creates one LinuxDVB adapter, and a demux/dvr/frontend set of devices for each tsin channel which is specificed in the DT. It has been tested with multiple tsin channels tuned, locked, and grabbing TS simultaneously. Signed-off-by:

The B2100A dvb NIM card from ST has 2x stv0367 demodulators and 2x TDA18212 silicon tuners, with a 16Mhz crystal. To get this working properly with the upstream driver we need to add support for the 16Mhz reference clock. Signed-off-by:

Peter Griffin authored
When using stv0367 demodulator with STi STB platforms, we can have easily have four or more stv0367 demods running in the system at one time. As typically the b2120 reference design ships with a b2004a daughter board, which can accept two dvb NIM cards, and each b2100A NIM has 2x stv0367 demods and 2x NXPs tuner on it. In such circumstances it is useful to print the i2c address on error messages to know which one is failing due to I2C issues. Signed-off-by:

The Linux stack is short; we need to be able to count the number of bytes used at stack on each function. So, we don't like to use variable-length arrays, as complained by smatch: drivers/media/dvb-frontends/horus3a.c:57:19: warning: Variable length array is used. The max usecase of the driver seems to be 10 bytes + 1 for the register. So, let's be safe and allocate 11 bytes for the write buffer. This should be enough to cover all cases. If not, let's print an error message. Signed-off-by: -
