Subject: [PATCH v3 2/4] gpio: tegra186: Allow optional irq parent callbacks
Date: Wed, 7 Oct 2020 13:45:42 +0100 [thread overview]
Message-ID: <20201007124544.1397322-3-maz@kernel.org> (raw)
In-Reply-To: <20201007124544.1397322-1-maz@kernel.org>
Make the tegra186 GPIO driver resistent to variable depth
interrupt hierarchy, which we are about to introduce.
No functionnal change yet.
