[media] tc358743: don't use variable length array for I2C writes · 1d88f831

Mauro Carvalho Chehab authored Aug 11, 2015

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.

[media] c8sectpfe: use a new Kconfig menu for DVB platform drivers · ca051897

While this is the first DVB platform drivers, let's keep the

Of course, it should depend on MEDIA_DIGITAL_TV_SUPPORT, as

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

This patch adds support for the c8sectpfe input HW found on

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.

Peter Griffin authored Jul 30, 2015

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.
