Subject: [PATCH v4 13/14] dmaengine: dw-edma-pcie: Add chip flags to match data
Date: Fri, 10 Jul 2026 17:15:17 +0900	[thread overview]
Message-ID: <20260710081518.2394357-14-den@valinux.co.jp> (raw)
In-Reply-To: <20260710081518.2394357-1-den@valinux.co.jp>

Allow PCI ID match data to pass dw_edma_chip flags into dw_edma_probe().
This keeps per-device policy in the match data instead of open-coding it
in probe().

Reviewed-by: Frank Li <Frank.Li@nxp.com>
