Subject: [PATCH 1/8] media: imx: Store the type of hardware implementation
From: Dorota Czaplejewicz <dorota.czaplejewicz@...i.sm>
The driver covers i.MX5/6, as well as i.MX7/8 hardware.
Those implementations differ, e.g. in the sizes of buffers they accept.
Some functionality should be abstracted, and storing type achieves that.
