Subject: [PATCH v2 02/11] drm/panthor: Move the register accessors before the IRQ helpers
Date: Tue, 12 May 2026 13:37:32 +0200 [thread overview]
Message-ID: <20260512-panthor-signal-from-irq-v2-2-95c614a739cb@collabora.com> (raw)
In-Reply-To: <20260512-panthor-signal-from-irq-v2-0-95c614a739cb@collabora.com>
We're about to add an IRQ inline helper using gpu_read(). Move things
around to avoid forward declarations.
No functional changes.
