Subject: [PATCH v6 3/7] gpio: ep93xx: Fix wrong irq numbers in port F
Date: Tue, 9 Feb 2021 16:31:06 +0300 [thread overview]
Message-ID: <20210209133110.7383-4-nikita.shubin@maquefel.me> (raw)
In-Reply-To: <20210209133110.7383-1-nikita.shubin@maquefel.me>
Port F IRQ's should be statically mapped to EP93XX_GPIO_F_IRQ_BASE.
So we need to specify girq->first otherwise:
"If device tree is used, then first_irq will be 0 and
IRQ's get mapped dynamically on the fly"
And that's not the thing we want.
