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
