Subject: media: ti-vpe: cal: Rename MAX_(WIDTH|HEIGHT)_* macros with CAL_ prefix Author: Laurent Pinchart <[email protected]> Date: Mon Dec 7 00:53:33 2020 +0100 The MAX_WIDTH_BYTES and MAX_HEIGHT_LINES macros have a generic name that is prone to namespace clashes. Rename them with a CAL_ prefix. While at it, expand their documentation and add CAL_MIN_(WIDTH|HEIGHT)_* macros that will be used to implement CAMERARX subdev operations.
