* [media] tvp5150: Add OF match tableEduard Gavin2016-01-251-0/+9
| | | | | | | | | | | | The Documentation/devicetree/bindings/media/i2c/tvp5150.txt DT binding doc lists "ti,tvp5150" as the device compatible string but the driver does not have an OF match table. Add the table to the driver so the I2C core can do an OF style match.

* [media] tvp5150: Configure data interface via DTJavier Martinez Canillas2016-01-251-3/+63
| | | | | | | | | | The video decoder supports either 8-bit 4:2:2 YUV with discrete syncs or 8-bit ITU-R BT.656 with embedded syncs output format but currently BT.656 it's always reported. Allow to configure the format to use via either platform data or a device tree definition.

* [media] tvp5150: Initialize the chip on probeJavier Martinez Canillas2016-01-251-0/+35
| | | | | | | | | | | | | | | | | | | | | | After power-up, the tvp5150 decoder is in a unknown state until the RESETB pin is driven LOW which reset all the registers and restarts the chip's internal state machine. The init sequence has some timing constraints and the RESETB signal can only be used if the PDN (Power-down) pin is first released. So, the initialization sequence is as follows: 1- PDN (active-low) is driven HIGH so the chip is power-up 2- A 20 ms delay is needed before sending a RESETB (active-low) signal. 3- The RESETB pulse duration is 500 ns. 4- A 200 us delay is needed for the I2C client to be active after reset. This patch used as a reference the logic in the IGEPv2 board file from the ISEE 2.6.37 vendor tree.

Read the version 5 size of nvram data from memory and then call the new checksum verification function from the header file.

There's nothing KVM specific about them, so lets move them into inst.h where they belong and delete the header. Note that mfmcz_op is renamed to mfmc0_op to match the instruction set manual, and wait_op was already added to inst.h in commit b0a3eae2b943 ("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.

To allow the use of these definitions by KVM for decoding cache ops, break the definitions down into parts where it makes sense to do so, and add masks for the Cache and Op field within the cache op.
