Subject: [RESEND PATCH v2 3/5] arm64: dts: ti: k3-am62-main: Add tidss clk-ctrl property
Date: Thu, 6 Nov 2025 19:42:25 +0530	[thread overview]
Message-ID: <20251106141227.899054-4-s-jain1@ti.com> (raw)
In-Reply-To: <20251106141227.899054-1-s-jain1@ti.com>

From: Louis Chauvet <louis.chauvet@bootlin.com>

For am62 processors, we need to use the newly created clk-ctrl property to
properly handle data edge sampling configuration. Add them in the main
device tree.

Fixes: ad2ac9dc9426 ("drm/tidss: Add support for AM625 DSS")
