Subject: [PATCH v2 3/5] dmaengine: mcf-edma: force type conversion for TCD pointer
Date: Thu, 16 Nov 2023 17:27:41 -0500 [thread overview]
Message-ID: <20231116222743.2984776-4-Frank.Li@nxp.com> (raw)
In-Reply-To: <20231116222743.2984776-1-Frank.Li@nxp.com>
The TCD structure undergoes changes, with some fields extending to 64 bits.
When TCD64 is enabled, the type of TCD changes to 'void *' . This addresses
the need to force the type conversion to 'struct fsl_edma_hw_tcd *' at
here.
