From 2dab504a9be138d6a8c94fe498bc7917d313182e Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Mon, 11 Oct 2021 11:03:31 +0200 Subject: libcamera: ipu3: Rationalize constant expressions names Following the previous patch that moved all the ImgU-related contants in the ImgUDevice class namespace and that aligned their naming scheme to the 'kNameOfConstant' scheme, apply the same changes to the other components of the IPU3 pipeline handler. Cosmetic change, no functional changes intended.
