Subject: [PATCH 03/12] ARM: ep93xx: enable SPARSE_IRQ
Date:   Tue,  5 Apr 2022 11:17:41 +0200
Message-Id: <20220405091750.3076973-4-arnd@kernel.org>
In-Reply-To: <20220405091750.3076973-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

Without CONFIG_SPARSE_IRQ, we rely on mach/irqs.h to define NR_IRQS
globally. Do the minimal conversion by setting .nr_irqs in each
machine descriptor.

Only the vision_ep9307 machine has extra IRQs for GPIOs, so make
.nr_irqs the original value there, while using the plain NR_EP93XX_IRQS
everywhere else.
