Subject: [PATCH for-7.1 14/18] hw/arm/exynos4210: Connect MCT_G0 and MCT_G1 to both combiners
Date: Mon,  4 Apr 2022 16:46:54 +0100	[thread overview]
Message-ID: <20220404154658.565020-15-peter.maydell@linaro.org> (raw)
In-Reply-To: <20220404154658.565020-1-peter.maydell@linaro.org>

Currently for the interrupts MCT_G0 and MCT_G1 which are
the only ones in the input range of the external combiner
and which are also wired to the external GIC, we connect
them only to the internal combiner and the external GIC.
This seems likely to be a bug, as all other interrupts
which are in the input range of both combiners are
connected to both combiners. (The fact that the code in
exynos4210_combiner_get_gpioin() is also trying to wire
up these inputs on both combiners also suggests this.)

Wire these interrupts up to both combiners, like the rest.
