Subject: [PATCH 11/27] drm: bridge: dw-hdmi: Pass private data pointer to .mode_valid()
Date: Tue, 26 May 2020 04:14:49 +0300 [thread overview]
Message-ID: <20200526011505.31884-12-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20200526011505.31884-1-laurent.pinchart+renesas@ideasonboard.com>
Platform glue drivers for dw_hdmi may need to access device-specific
data from their .mode_valid() implementation. They currently have no
clean way to do so, and one driver hacks around it by accessing the
dev_private data of the drm_device retrieved from the connector.
Add a priv_data void pointer to the dw_hdmi_plat_data structure, and
pass it to the .mode_valid() function.
