From 13efd80acaa4cdb61fde52732178ff9eb4141104 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 21 Jun 2019 20:02:03 +0200 Subject: ARM: dts: exynos: Add GPU/Mali 400 node to Exynos4 Add nodes for GPU (Mali 400) to Exynos4210 and Exynos4412. Describe the GPU as much as possible however still few elements are missing: 1. Exynos4210 bus clock is not described in hardware manual therefore the IP gate clock was provided, 2. Exynos4412: Not sure what to do with CLK_G3D clock responsible for gating entire IP block (it is now being disabled as unused), 3. Regulator supplies on Trats board. Limited testing on Odroid U3 (Exynos4412).
