[PATCH 15/22] media: sunxi: Remove the sun6i-csi driver implementation
Paul Kocialkowski

Fri Sep 10 11:41:40 PDT 2021
As described in the commit adding support for the new sun6i-csi driver,
a complete rewrite was necessary to support the Allwinner A31 ISP as
well as fix a number of issues with the current implementation.
Farewell and thanks for all the pixels!
