2015-08-11[media] c8sectpfe: Add Kconfig and Makefile for the driverPeter Griffin
This patch adds the Kconfig and Makefile for the c8sectpfe driver so it will be built. It also selects additional demodulator and tuners which are required by the supported NIM cards.

2015-08-11[media] c8sectpfe: Add c8sectpfe debugfs supportPeter Griffin
Some basic debugfs support to dump the IP registers. Further statistics could easily be added in the future for example for each enabled tsin channel we could expose number of corrupt packets received etc. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-08-11[media] c8sectpfe: Add support for various ST NIM cardsPeter Griffin
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.

2015-08-11[media] c8sectpfe: Add LDVB helper functionsPeter Griffin
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.

2015-08-11[media] c8sectpfe: STiH407/10 Linux DVB demux supportPeter Griffin
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.

2015-08-11[media] ARM: DT: STi: STiH407: Add c8sectpfe LinuxDVB DT nodePeter Griffin
This patch adds in the required DT node for the c8sectpfe Linux DVB demux driver which allows the tsin channels to be used on an upstream kernel. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-08-11[media] c8sectpfe: Add DT bindings documentation for c8sectpfe driverPeter Griffin
This patch adds the DT bindings documentation for the c8sectpfe LinuxDVB demux driver whose IP is in the STiH407 family silicon SoC's. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-08-11[media] stv0367: Add support for 16Mhz reference clockPeter Griffin
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.
