The following add driver patches for porting TI's am335x and am437x devices to the sdhci-omap driver.
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.
I need some help with testing all the other beaglebone variants and SDIO Wifi cards.
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. Fixed subject line for dt-bindings patch.
