[RFC PATCH v1 0/2] Add basic HDCP function support for dw_hdmi driver

Hi,

This series try to add the basic HDCP function support for bridge dw_hdmi driver. Beside this series also resend the patch from Sean Paul that try to introduce a common way for userspace to operate the HDCP function.

Userspace could chose to enable/disable the HDCP function throught the new standard properties "Content Protection", and driver would reflect the HDCP auth status to "Content Protection KSV" property.

Beside this series also base on Vladimir Zapolskiy's patch that help to introduce DDC support for dw_hdmi driver.

[Resend] Sean Pual: https://patchwork.kernel.org/patch/7279801 [Rebased on] Vladimir Zapolskiy: https://patchwork.kernel.org/patch/7279801

Thanks - Yakir
