Subject: [PATCH v4 3/4] drm/rockchip: dw_hdmi: Add support for 4k@30 resolution
Date: Tue,  7 Feb 2023 09:44:51 +0100	[thread overview]
Message-ID: <20230207084452.1069656-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230207084452.1069656-1-s.hauer@pengutronix.de>

This adds the PLL/phy settings to support higher resolutions like 4k@30.
The values were taken from the Rockchip downstream Kernel.
