From b76ebc473bac2170b944a8cee39cd17b62d0226b Mon Sep 17 00:00:00 2001 From: Liu Ying Date: Mon, 3 Jul 2017 11:35:52 +0800 Subject: dt-bindings: display: fsl-imx-drm: Add i.MX8 PRG(Prefetch Resolve Gasket) support The Pretch Resolve Gasket(PRG) is a digital core function as a gasket interface between RTRAM controller and DPU. The main function of PRG is to convert the AXI interface to RTRAM interface and remapping the ARADDR to a RTRAM address. This patch adds device tree binding doc support for i.MX8qm/qxp PRG.
