From 275fa9252047a4b7e81be2835ba83b2aac8d080f Mon Sep 17 00:00:00 2001 From: Christoph Muellner Date: Tue, 13 Nov 2018 16:15:27 +0100 Subject: arm64: DTS: rk3399-puma.dts: Update DMC OPs. Extending the operating point list of the DMC to include frequencies of up to 800 MHz. This increases bandwidth and fixes issues observed with RKISP1 (PIC_SIZE_ERRORs when performing memory intensive tasks in parallel).
