Subject: [PATCH 2/6] ARM: ep93xx: enable SPARSE_IRQ
Date:   Fri, 18 Oct 2019 18:29:15 +0200
Message-Id: <20191018163047.1284736-2-arnd@arndb.de>
In-Reply-To: <20191018163047.1284736-1-arnd@arndb.de>

Precedence: bulk

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.

---
It's been a while since I did this, no idea what else is needed
here or if this is correct at all.
