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.
