Subject: [PATCH v2 13/16] gpio: omap: Drop irq_base
Date: Tue, 07 Mar 2023 14:04:55 +0100	[thread overview]
Message-ID: <20230215-immutable-chips-v2-13-d6b0e3f2d991@linaro.org> (raw)
In-Reply-To: <20230215-immutable-chips-v2-0-d6b0e3f2d991@linaro.org>

The OMAP1 at one point was using static irqs but that time is gone,
OMAP1 uses sparse irqs like all other multiplatform targets so this
static allocation of descriptors should just go.
