From bf09924f21767e6bb7cb3aae48c48c2c2ab8261a Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Thu, 2 May 2019 15:53:34 -0700 Subject: [PATCH 45/54] ARM: dts: rockchip: Switch to builtin HDMI DDC bus on rk3288-veyron Downstream Chrome OS kernels use the builtin DDC bus from dw_hdmi on veyron. This is the only way to get them to negotiate HDCP. Although HDCP isn't currently all supported upstream, it still seems like it makes sense to use dw_hdmi's builtin I2C. Maybe eventually we can get HDCP negotiation working.
