This involves adding external DMA support to sdhci (first 3 patches from Chunyan) plus some miscellaneous patches to take care of deviations of the controllers from the sdhci model. DT changes will be posted in a separate series. Untested versions of Chunyan's patches were posted before[1]. Tested on: am335x-evm, am335x-boneblack, am335x-sk, am437x-gpevm, am43xx-gpevm, am437x-idk, dra7xx-evm, dra72x-evm v2: 1. sdhci is using two bottom halves. One threaded_rq for card detect and a tasklet for finishing mmc requests. Patch 1 removes the tasklet and moves its function to the threaded_irq. This enables me to terminate_sync() in sdhci_request_done() 2. Factored out common code for between the normal adn external dma case 3. Using existing API sdhci_data_timeout_irq for disabling DTO during erase commands. 4. Fixed subject line for dt-bindings patch.
