Subject: [PATCH v3 1/2] dt-bindings: timer: sifive,clint: Fix number of interrupts
Date: Fri, 17 Dec 2021 13:38:03 +0100	[thread overview]
Message-ID: <4f409ac939e260a4657a0e6e6518ef8736527822.1639744468.git.geert@linux-m68k.org> (raw)
In-Reply-To: <cover.1639744468.git.geert@linux-m68k.org>

The number of interrupts lacks an upper bound, thus assuming one,
causing properly grouped "interrupts-extended" properties to be flagged
as an error by "make dtbs_check".

Fix this by adding the missing "maxItems".  As the architectural maximum
is 4095 interrupts, using that as the limit would be unpractical.  Hence
limit it to 10 interrupts (two interrupts for a system management core,
and two interrupts per core for other cores).  This should be sufficient
for now, and the limit can always be increased when the need arises.
