From b638823a7bbd251d442042b0e9522100bdaa5b66 Mon Sep 17 00:00:00 2001 From: Alejandro Mery Date: Tue, 5 Dec 2017 12:34:56 +0000 Subject: ARM: davinci: Use platform_device_register_full() to create pdev for dm365's eDMA Convert the DM365 EDMA platform device creation to use struct platform_device_info XXXXXX __initconst and platform_device_register_full() This will allow us to specify the dma_mask for the device in an upcoming patch. Without this, EDMA on DM365 refuses to probe.
