Kconfig: Remove all default n/no options

2021-08-31T21:47:49Z

default n/no doesn't need to be specified. It is default option anyway. Signed-off-by: Michal Simek [trini: Rework FSP_USE_UPD portion] Signed-off-by: Tom Rini

dma: ti: k3-udma: Add support for native configuration of chan/flow

2021-06-11T13:48:52Z

In absence of Device Manager (DM) services such as at R5 SPL stage, driver will have to natively setup TCHAN/RCHAN/RFLOW cfg registers. Add support for the same. Note that we still need to send chan/flow cfg message to TIFS via TISCI client driver in order to open up firewalls around chan/flow but setting up of cfg registers is handled locally. U-Boot specific code is in a separate file included in main driver so as to maintain similarity with kernel driver in order to ease porting of code in future.

dma: ti: k3-udma: Add BCDMA and PKTDMA support

2021-05-12T11:06:38Z

Sync BCDMA and PKTDMA support from Kernel for AM64 SoC Signed-off-by: Vignesh Raghavendra

dma: ti: k3-psil-am64: Add AM64 PSIL endpoint data

2021-05-12T11:06:38Z

Add AM64 SoC specific channel mapping and endpoint data. Signed-off-by: Vignesh Raghavendra

dma: ti: k3-psil: Extend PSIL EP data extension for AM64

2021-05-12T11:06:38Z

Extend PSIL EP data to include AM64 DMA specific information Signed-off-by: Vignesh Raghavendra

dma: ti: k3-psil-am654: Drop unused PSIL EP static data

2021-05-12T11:06:38Z

ICSSG Ethernet driver uses two src threads per port (one per slice). Similarly CPSW uses one src thread. Drop PSIL EP static data for other src threads in order to reduce R5 SPL footprint. This makes AM65x board bootable again. Signed-off-by: Vignesh Raghavendra

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25Z

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

dma: ti: k3-udma: Reset the channel during release

2020-10-12T02:39:18Z

Reset the channel completely during channel release in order to clear teardown bit before handing over to next user or jumping to Linux. Signed-off-by: Vignesh Raghavendra Reviewed-by: Grygorii Strashko

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
