Subject: [PATCH v3 08/12] dmaengine: fsl-edma: move clearing of register interrupt into setup_irq function
Date: Thu,  1 Jun 2023 10:41:03 -0400	[thread overview]
Message-ID: <20230601144107.1636833-9-Frank.Li@nxp.com> (raw)
In-Reply-To: <20230601144107.1636833-1-Frank.Li@nxp.com>

This accommodates differences in the register layout of EDMA v3 by moving
the clearing of register interrupts into the platform-specific set_irq
function. This should ensure better compatibility with EDMA v3.
