[PATCH v3 19/46] media: rkisp1: Split CSI handling to separate file
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Mon Jul 11 05:42:21 PDT 2022
From: Paul Elder <paul.elder at ideasonboard.com>
Not all ISP instances include a MIPI CSI-2 receiver. To prepare for
making it optional, move code related to the CSI-2 receiver to a
separate file.

Changes since v2:
- Add forward declaration of struct rkisp1_csi
Changes since v1:
- Initialize csi->rkisp1
- Fix dev_err_probe() usage
- Fix white space issue
