Subject: [PATCH v2 17/29] drm/sun4i: dw-hdmi: Make mode_valid function configurable
Date: Sun, 7 Oct 2018 11:38:53 +0200 [thread overview]
Message-ID: <20181007093905.11253-18-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20181007093905.11253-1-jernej.skrabec@siol.net>
Since it is not possible to access sun8i-dw-hdmi driver private data
inside mode_valid function, make it configurable. That way different
versions of HDMI controllers can set different function, depending on
it's limitations.
