Patch [1/2] of the series moves some structures and API definition to .h files so that these can be accessed by taprio (icssg_qos.c) file. Patch [2/2] of the series intoduces the taprio support for icssg driver. Changes from v5 to v6: *) Added RFC tag as net-next is closed now. *) Created a new patch for "the struct definition move" and made this series instead of single patch as suggested by Paolo Abeni . *) Removed est_new structure as that is no longer used. *) Freeing qos.tas.taprio_admin using taprio_offload_free() as suggested by Paolo Abeni *) Clearing taprio_admin and taprio in error case in emac_taprio_replace() API using goto label taprio_clear. *) Added RB tag of Simon Horman Changes from v4 to v5: *) Rebased on latest net-next/main [commit 5c4c0edca68a] *) Moved icss_iep structure to icss_iep.h file so that iep wraparound time which is stored in iep->def_inc, can be accessed by qos file. *) Added comment about IEP wraparound time compensation in icssg_qos.c *) Moved icssg_qos_tas_init() to prueth_netdev_init() so that icssg_qos_tas_init() gets called even if interface is down. *) Fixed print statements as suggested by Vladimir Oltean *) Added taprio_offload_get() and taprio_offload_free() in emac_taprio_replace() and emac_taprio_destory() respectively. Changes from v3 to v4: *) Rebased on the latest next-20231005 linux-next. *) Addressed Roger and Vinicius' comments and moved all the validations to emac_taprio_replace() API. *) Modified emac_setup_taprio() API to use switch case based on taprio->cmd and added emac_taprio_destroy() and emac_taprio_replace() APIs. *) Modified the documentation of structs / enums in icssg_qos.h by using the correct kdoc format. Changes from v2 to v3: *) Rebased on the latest next-20230928 linux-next. *) Retained original authorship of the patch. *) Addressed Roger's comments and modified emac_setup_taprio() and emac_set_taprio() APIs accordingly. *) Removed netif_running() check from emac_setup_taprio(). *) Addressed Vinicius' comments and added check for MIN and MAX cycle time. *) Added check for allocation failure of est_new in emac_setup_taprio(). Changes from v1 to v2: *) Rebased on the latest next-20230921 linux-next. *) Dropped the RFC tag as merge window is open now. *) Splitted this patch from the switch mode series [v1]. *) Removed TODO comment as asked by Andrew and Roger. *) Changed Copyright to 2023 as asked by Roger. v5: https://lore.kernel.org/all/20240429103022.808161-1-danishanwar@ti.com/ v4: https://lore.kernel.org/all/20231006102028.3831341-1-danishanwar@ti.com/ v3: https://lore.kernel.org/all/20230928103000.186304-1-danishanwar@ti.com/ v2: https://lore.kernel.org/all/20230921070031.795788-1-danishanwar@ti.com/ v1: https://lore.kernel.org/all/20230830110847.1219515-1-danishanwar@ti.com/ MD Danish Anwar (1): net: ti: icssg: Move icss_iep structure Roger Quadros (1): net: ti: icssg_prueth: add TAPRIO offload support drivers/net/ethernet/ti/Kconfig | 1 + drivers/net/ethernet/ti/Makefile | 3 +- drivers/net/ethernet/ti/icssg/icss_iep.c | 72 ----- drivers/net/ethernet/ti/icssg/icss_iep.h | 73 ++++- drivers/net/ethernet/ti/icssg/icssg_prueth.c | 5 +- drivers/net/ethernet/ti/icssg/icssg_prueth.h | 5 + drivers/net/ethernet/ti/icssg/icssg_qos.c | 288 +++++++++++++++++++ drivers/net/ethernet/ti/icssg/icssg_qos.h | 113 ++++++++ 8 files changed, 485 insertions(+), 75 deletions(-) create mode 100644 drivers/net/ethernet/ti/icssg/icssg_qos.c create mode 100644 drivers/net/ethernet/ti/icssg/icssg_qos.h base-commit: cddd2dc6390b90e62cec2768424d1d90f6d04161
