Subject: RE: [PATCH v5 3/3] drivers: dma: sh: Add DMAC driver for RZ/G2L SoC

Message-ID: <OS0PR01MB5922C288A894BF28E5E03A2186EB9@OS0PR01MB5922.jpnprd01.prod.outlook.com> (raw)

Hi All,

Sorry for the noise. Please ignore my previous mails. %pad with reference to dma_addr_t type fixed the issue.

Tested with aarch64 and nios2 tool chain.
