[libcamera-devel] [PATCH v6 08/10] ipa: rkisp1: Add AF controls to the RkISP1 IPA

[Daniel Semkowicz]

Add controls supported by the AF algorithm to the list of controls
supported by the RkISP1 IPA. This exposes the AF controls to the user
and allows controlling the AF algorithm using the top level API.
