dmaengine: Switch back to struct platform_driver::remove()

2024-10-14T18:20:34Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/dma after the previous conversion commits apart from the wireless drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

dmaengine: ti: k3-udma: Set EOP for all TRs in cyclic BCDMA transfer

2024-10-14T18:11:05Z

When receiving data in cyclic mode from PDMA peripherals, where reload count is set to infinite, any TR in the set can potentially be the last one of the overall transfer. In such cases, the EOP flag needs to be set in each TR and PDMA's Static TR "Z" parameter should be set, matching the size of the TR. This is required for the teardown to function properly and cleanup the internal state memory. This only affects platforms using BCDMA and not those using UDMA-P, which could set EOP flag in the teardown TR automatically. Similarly when transmitting data in cyclic mode to PDMA peripherals, the EOP flag needs to be set to get the teardown completion signal correctly.

dmaengine: ti: omap-dma: Initialize sglen after allocation

2024-08-05T16:58:13Z

With the new __counted_by annocation, the "sglen" struct member must be set before accessing the "sg" array. This initialization was done in other places where a new struct omap_desc is allocated, but these cases were missed. Set "sglen" after allocation.
