Move av7110 driver to staging
Subsystems (2)
v2 cover Move av7110 driver to staging
This driver was written for a hardware manufactured by TI from a design made by Convergence. Such hardware supports only MPEG2, which doesn't fit most of the current DVB transmissions.
It stopped being manufactured more than a decade ago.
Also, recent checks identified that a frontend used by such driver was broken for sometime without nobody noticing it.
It means that it is time to retire it for good.
This series move both av7110 and sp8870 frontend drivers (which is used only by av7110) to staging, while keeping the remaining ttpci support upstream.
It also moves ttpci-eeprom to a common place, as it is used by both a PCI and an USB driver.
---
v2:
- Fix a typo at the TODO file;
- Add a note at TODO that cleanup patches won't be accepted;
- Changed the description of the second patch.

PATCH v2 1/3 media: move ttpci-eeprom to common
The ttpci-eeprom is actually an independent driver that doesn't depend on the stuff under drivers/media/pci/ttpci/.
Also, it is used by an USB driver (pctv452e).
So, move it to the common directory.

PATCH v2 2/3 media: av7110: move driver to staging
In reply to Mauro Carvalho ChehabThis driver is really old, from devices that aren't manufactured anymore for more than a decade.
Also, the decoder supports only MPEG2, with is not compatible with several modern DVB streams.
It is also the only upstream driver relying on the DVB "full-featured" API.
Some changes at the frontend drivers seem to have broken it without anybody noticing.
Due to that, it sounds it is time to retire the driver for good.

PATCH v2 3/3 media: sp8870: move it to staging
In reply to Mauro Carvalho ChehabThis driver is used only by av7110, which is preparing for its retirement. So, move this ancillary driver to stay together with av7110.
