From 1a4a66ddc7b290ea2fd492c9c922ee7205d44724 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Mon, 30 Jan 2017 10:46:35 -0500 Subject: drm/msm: remove qcom,gpu-pwrlevels bindings The plan is to use the OPP bindings. For now, remove the documentation for qcom,gpu-pwrlevels, and make the driver fall back to a safe low clock if the node is not present. Note that no upstream dtb use this node. For now we keep compatibility with this node to avoid breaking compatibility with downstream android dt files.
