Patches 1-4 Add Support for external DMA to the sdhci driver. Patches 5-7 refactor the sdhci_set_timeout() function and use it disable data timeout interrupt for erase commands Patches 8-9 add new compatibles for am335x and am43xx devices to the sdhci-omap driver. Patch 10 implements special reset required for am335x and am437x devices. DT changes will be posted as a separate series. Tested on: am335x-evm, am335x-boneblack, am335x-bonegreen-wireless, am335x-sk, am335x-bone, am437x-idk, am43xx-gp-evm, am43xx-epos-evm. v5: 1. Patch 3 now uses the dma_submit_error() API instead of checking the cookie on its own. 2. Dropped the patch adding ti,needs-special-reset property to sdhci-omap. Using a flag in the driver instead. 3. Minor spacing changes. v4: 1. Made the factoring out of initialize_data, block_info and mrqs_done as a separate patch 2. Replaced the patch introducing the quirk to disable DTO during erase operations to a set_timeout() callback in sdhci-omap 3. Ported the ti,needs-special-reset property from omap_hsmmc to sdhci-omap. 4. Minor style changes. v3: 1. Dropped patch 1 because the tasklet was removed by Adrian in an earlier series. 2. Added dma bindings in sdhci-omap as optional properties. 3. Rebased on top of latest mainline. 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.
