Subject: [PATCH v6 04/19] dmaengine: ti: k3-udma: move static inline helper functions to header file
Date: Tue, 28 Apr 2026 14:21:33 +0530	[thread overview]
Message-ID: <20260428085202.1724548-5-s-adivi@ti.com> (raw)
In-Reply-To: <20260428085202.1724548-1-s-adivi@ti.com>

Move static inline helper functions in k3-udma.c to k3-udma.h header
file for better separation and reuse.
