Subject: [PATCH 1/3] dt-bindings: display: synopsys,dw-hdmi: Add property for disabling CEC
Date: Sat, 15 Apr 2023 12:46:11 +0200 [thread overview]
Message-ID: <20230415104613.61224-2-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20230415104613.61224-1-jernej.skrabec@gmail.com>
Even though some DW-HDMI controllers have perfectly usable HDMI-CEC
implementation, some boards might prefer not to use it or even use
software implementation instead.
Add property for disabling CEC so driver doesn't expose unused CEC
interface, if CEC pin isn't connected anywhere.
