2023-03-31dmaengine: ti: k3-udma: Add system suspend/resume supportVignesh Raghavendra
The K3 platforms configure the DMA resources with the help of the TI's System Firmware's Device Manager(DM) over TISCI. The group of DMA related Resource Manager[1] TISCI messages includes: INTA, RINGACC, UDMAP, and PSI-L. This configuration however, does not persist in the DM after leaving from Suspend-to-RAM state. We have to restore the DMA channel configuration over TISCI for all configured channels when returning from suspend. The TISCI resource management calls for each DMA type (UDMA, PKTDMA, BCDMA) happen in device_free_chan_resources() and device_alloc_chan_resources(). In pm_suspend() we store the current udma_chan_config for channels that still have attached clients and call device_free_chan_resources(). In pm_resume() restore the udma_channel_config from backup and call device_alloc_chan_resources() for those channels. Drivers like CPSW that use k3-udma-glue already do their own DMA resource management so use the late system suspend/resume hooks.

2022-10-19dmaengine: ti: convert k3-udma to moduleKevin Hilman
Currently k3-udma driver is built as separate platform drivers with a shared probe and identical code path, just differnet platform data. To enable to build as module, convert the separate platform driver into a single module_platform_driver with the data selection done via compatible string and of_match. The separate of_match tables are also combined into a single table to avoid the multiple calls to of_match_node() Since all modern TI platforms using this are DT enabled, the removal of separate platform_drivers should have no functional change.

If the DMA consumer driver does not expect the callback for TX done, then we need not perform the channel RT byte counter calculations and estimate the completion but return complete on first attempt itself.This assumes that the consumer who did not request DMA_PREP_INTERRUPT has its own mechanism for understanding TX completion, example: MCSPI EOW interrupt can be used as TX completion signal for a SPI transaction.

2022-09-05dmaengine: ti: k3-udma: Reset UDMA_CHAN_RT byte counters to prevent overflowVaishnav Achath
UDMA_CHAN_RT_*BCNT_REG stores the real-time channel bytecount statistics. These registers are 32-bit hardware counters and the driver uses these counters to monitor the operational progress status for a channel, when transferring more than 4GB of data it was observed that these counters overflow and completion calculation of a operation gets affected and the transfer hangs indefinitely. This commit adds changes to decrease the byte count for every complete transaction so that these registers never overflow and the proper byte count statistics is maintained for ongoing transaction by the RT counters. Earlier uc->bcnt used to maintain a count of the completed bytes at driver side, since the RT counters maintain the statistics of current transaction now, the maintenance of uc->bcnt is not necessary.

udma_get_*() checks if rchan/tchan/rflow is already allocated by checking if it has a NON NULL value. For the error cases, rchan/tchan/rflow will have error value and udma_get_*() considers this as already allocated (PASS) since the error values are NON NULL. This results in NULL pointer dereference error while de-referencing rchan/tchan/rflow. Reset the value of rchan/tchan/rflow to NULL if a channel request fails.
