Subject: [PATCH 0/2] clock: versal-clk: Fix Versal NET clock binding and switch to CCF
Date: Thu, 5 Mar 2026 16:39:48 +0100	[thread overview]
Message-ID: <cover.1772725183.git.michal.simek@amd.com> (raw)

This series fixes the Versal NET clock controller DT binding validation
and switches the platform to use the firmware-based CCF clock interface.

Patch 1 restructures the if/then conditions in the versal-clk binding
schema so that xlnx,versal-net-clk is matched first before falling back
to xlnx,versal-clk. This fixes false "too long" validation errors caused
by both conditions matching simultaneously when the fallback compatible
is present. A dedicated example for the Versal NET 3-clock configuration
is added and all examples are split into separate blocks for independent
validation.

Patch 2 switches Versal NET from static fixed-clock definitions to the
firmware-based CCF clock interface, enabling proper clock management
through platform firmware. DT macro headers for clocks, power domains
and resets are added.

Thanks,
Michal
