Subject: [PATCH 1/6] drm/sun4i: sun8i-hdmi-phy: Use of_device_get_match_data
Date: Mon, 11 Apr 2022 23:35:06 -0500	[thread overview]
Message-ID: <20220412043512.49364-2-samuel@sholland.org> (raw)
In-Reply-To: <20220412043512.49364-1-samuel@sholland.org>

Now that the HDMI PHY is using a platform driver, we can use the usual
helper function for getting the variant structure.
