From 4fa2d09c1ae879c2ee2760ab419a4f97026dd97b Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 16 Dec 2015 15:19:05 +0200 Subject: [PATCH] dmaengine: edma: Add probe callback to edma_tptc_driver Due to changes in device and platform code drivers w/o probe will fail to load. This means that the devices for eDMA TPTCs are goign to be without driver and omap hwmod code will turn them off after the kernel finished loading: [ 3.015900] platform 49800000.tptc: omap_device_late_idle: enabled but no driver. Idling [ 3.024671] platform 49a00000.tptc: omap_device_late_idle: enabled but no driver. Idling This will prevent eDMA to work since the TPTCs are not enabled.
