Subject: [PATCH 1/1] dt-bindings: usb: ci-hdrc-usb2: Fix number of clocks
Date: Thu,  6 Jul 2023 11:39:28 +0200	[thread overview]
Message-ID: <20230706093928.3580544-1-alexander.stein@ew.tq-group.com> (raw)

Some (older) IP cores require 3 clocks, named 'ipg', 'ahb' and 'per' while
more recent IP cores just require one. Fix the number and explicitly
state the clock-names.

Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com>

From I can tell, is that imx25, imx27, imx35 have specified 3 clocks in
their DT.
IMHO minItems for 'clock-names' can be removed as I presume that this
property is not set when only one clock is used.
