dma: ti: k3-udma: Switch to k3_ringacc_request_rings_pair

2020-07-13T15:28:34Z

We only request ring pairs via K3 DMA driver, switch to use the new k3_ringacc_request_rings_pair() to simplify the code. As a good side effect, all boot stages now use exposed RING mode which avoid maintaining proxy mode for 32 bit R5 core. Signed-off-by: Vignesh Raghavendra

dma: ti: k3-udma: Move RX descriptor ring entries to rflow struct

2020-07-13T15:28:34Z

In K3 UDMA architecture, RX rings are associated with RX flows rather than RX channels, therefore move the ring pointers to udma_rflow struct Signed-off-by: Vignesh Raghavendra

dma: ti: k3-udma: Introduce udma_chan_config struct

2020-07-13T15:28:34Z

Encapsulate channel configuration in a separate struct so as to ease resetting of these fields with memset() and also to increase readability of the code. Signed-off-by: Vignesh Raghavendra

dma: ti: k3-udma: Update driver to use static endpoint Data

2020-07-13T15:28:34Z

Update driver to use static PSIL endpoint Data instead of DT. This will allow DT bindings to be in sync with kernel's DT. Note that this patch breaks networking and OSPI boot as driver changes are not backward compatible with existing DT. Subsequent commit will update the DT to make it compatible with updated driver.

dma: ti: Add static PSIL endpoint information

2020-07-13T15:28:34Z

Much of PSIL endpoint configuration for a given SoC can be known at compile time, therefore pass them for platform specific data instead of DT. Add per SoC's specific PSIL endpoint data. This is to bring driver in sync with upstream DT. Signed-off-by: Vignesh Raghavendra Reviewed-by: Grygorii Strashko

common: Drop linux/bitops.h from common header

Move this uncommon header out of the common header. Signed-off-by: Simon Glass

common: Drop net.h from common header

2020-05-18T21:33:31Z

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass

dma: ti: k3-udma: Mark flow id as valid parameter for RX channel config

2020-03-03T07:38:14Z

When flow id is not marked as valid, sysfw reads the register value to get the range of flow ids that are supported. Then compares the flow range with the U-Boot's host id. This will definitely fail as board configuration doesn't assign the full range to U-Boot's host id. In order to work around this, mark the flow id as valid and pass range as 0.

dma-mapping: move dma_map_(un)single() to

2020-02-19T13:27:30Z

The implementation of dma_map_single() and dma_unmap_single() is exactly the same for all the architectures that support them. Factor them out to , and make all drivers to include instead of . If we need to differentiate them for some architectures, we can move the generic definitions to . Add some comments to the helpers. The concept is quite similar to the DMA-API of Linux kernel. Drivers are agnostic about what is going on behind the scene. Just call dma_map_single() before the DMA, and dma_unmap_single() after it. Signed-off-by: Masahiro Yamada
