These are cherry-picked & backported from LKML: *https://lkml.org/lkml/2015/3/17/19 They are enabled on both 3.18 and 4.1 kernel. Patches 150 to 154 are applying changes merged since 3.18; they enable mechanisms used by the ADM driver. ADM engine is used by the NAND controller, so it is necessary to bring-up NAND flash support.

Subject: [PATCH] dmaengine: Remove the need to declare device_control
|
|
|
|
In order to migrate the drivers without triggering a BUG_ON for the converted
|
|
drivers, which would cause bisectability issues, we need to remove that check
|
|
before removing the device_control function entirely.
