Subject: [PATCH v5 02/12] phy: hdmi: Add color depth configuration
Date: Sat, 08 Mar 2025 14:21:11 +0200	[thread overview]
Message-ID: <20250308-phy-sam-hdptx-bpc-v5-2-35087287f9d1@collabora.com> (raw)
In-Reply-To: <20250308-phy-sam-hdptx-bpc-v5-0-35087287f9d1@collabora.com>

Extend the HDMI configuration options to allow managing bits per color
channel.  This is required by some PHY drivers such as
rockchip-samsung-hdptx.
