[libcamera-devel] [PATCH 1/2] ipa: rkisp1: Split queuing of request and parameter filling

[Umang Jain]

Queuing of request (i.e. passing of controls to the IPA)
and filling of the parameters buffer are two separate operations.
Treat them as such by splitting them into two functions in
the rkisp1 IPA interface.
