Subject: [PATCH v2 0/6] dmaengine: axi-dmac: add support for reading bus attributes from register

The series adds support for reading the DMA bus attributes from the
INTERFACE_DESCRIPTION (0x10) register.

The first 5 changes are a bit of rework prior to adding the actual
change in patch 6, as things need to be shifted around a bit, to enable 
the clock to be enabled earlier, to be able to read the version
register.

Changelog v1 -> v2:
* fixed error-exit paths for the clock move patch
  i.e. 'dmaengine: axi-dmac: move clock enable earlier'
* fixed error-exit path for patch
  'axi-dmac: wrap channel parameter adjust into function'
* added patch 'dmaengine: axi-dmac: move active_descs list init after device-tree init'
  the list of active_descs can be moved a bit lower in the init/probe

Alexandru Ardelean (6):
  dmaengine: axi-dmac: move version read in probe
  dmaengine: axi-dmac: move active_descs list init after device-tree
    init
  dmaengine: axi-dmac: move clock enable earlier
  dmaengine: axi-dmac: wrap entire dt parse in a function
  dmaengine: axi-dmac: wrap channel parameter adjust into function
  dmaengine: axi-dmac: add support for reading bus attributes from
    registers
