Subject: [PATCH v2 05/33] ARM: dts: am62l: Fix assigned-clock-parents
Date: Thu, 05 Jun 2025 14:42:30 +0200	[thread overview]
Message-ID: <20250605-arm-k3-am62l-v2-5-53257d4b2dd2@pengutronix.de> (raw)
In-Reply-To: <20250605-arm-k3-am62l-v2-0-53257d4b2dd2@pengutronix.de>

The AM62l device trees we imported to barebox have problems with the
clock parents which is described in [1] and [2].

There is no way the Kernel or barebox SCMI clk drivers can work with the
current way the clk parents are specified in the downstream TF-A. This
problem is acknowledged by TI and will hopefully be fixed.

This patch fixes the clk parents the way that I hope TI will do it as
well. Currently this only works with a patched downstream TF-A.
