-Subject: [PATCH 2/2] src: most: add auto conf feature
-
-This patch adds the auto configuration feature to the driver
-sources. It is needed to have the driver configured automatically
-upon start up w/o the need for userspace to set up sysfs.

-Subject: [PATCH] staging: most: dim2: use device tree
-
-Current dim2 driver expects the existence of a platform driver that
-implements the platform specific initialization and delivery of the irq
-numbers.
-
-This patch integrates the device tree activity and platform specific
-code into the driver.

-Subject: [PATCH] staging: most: dim2: use device for coherent memory allocation
-
-On several modern architectures the allocation of coherent memory needs
-a device that has the dma_ops properly set. This patch enables use of
-the DIM2 platform device for the allocation process.
