StarFive no longer plans to maintain or develop the JH7110 camera
subsystem for destaging, as discussed in below thread:
https://lore.kernel.org/all/ZQ0PR01MB13024A92926C415C187D2C18F29F2@ZQ0PR01MB1302.CHNPR01.prod.partner.outlook.cn/
So drop the driver and bindings from staging. This came up while adding
support for streams APIs in Cadence CSI2RX driver, which is used both by
StarFive and TI in their capture pipelines:

Changes in v2:
- Add Changhuang's Ack on PATCH 1
- Fix PATCH 2 to also drop reference to the starfive camss documentation
in v4l-drivers.rst
- Link to v1: https://lore.kernel.org/r/20260115-drop-starfive-camss-v1-0-27550e7a9815@ideasonboard.com

Maybe > someone will volunteer for it? It's in staging, nobody has registered any interest, the company behind the hardware as publicly said they won't continue development, and there's no documentation. I think that meets the bar for dropping the driver. In the very unlikely case someone would want to revive it, the source code will live in git history. > >> Link: https://lore.kernel.org/all/ZQ0PR01MB13024A92926C415C187D2C18F29F2@ZQ0PR01MB1302.CHNPR01.prod.partner.outlook.cn/ > >> Acked-by: Changhuang Liang <changhuang.liang@starfivetech.com> > >> Signed-off-by: Jai Luthra <jai.luthra@ideasonboard.com> > > > > Reverting/dropping changes is always in reverse of introducing them, so > > this must be second commit.
