The major difference between v1 and v2 hw is support for SATA/STP. Known limitation: - We cannot connect a SATA disk through an expander which enables DMA setup auto-activate, as our controller does not support this feature. Directly connecting a SATA disk to the HBA is ok. Differences to v1: - Update dt bindings, specificially for am-max-transmissions - some small SATA fixes - minor formatting changes John Garry (23): devicetree: bindings: hisi_sas: add v2 HW bindings hisi_sas: relocate DEV_IS_EXPANDER hisi_sas: set max commands as configurable hisi_sas: reduce max itct entries hisi_sas: add hisi_sas_err_record_v1 hisi_sas: rename some fields in hisi_sas_itct hisi_sas: add bare v2 hw driver hisi_sas: add v2 register definitions hisi_sas: add v2 hw init hisi_sas: add init_id_frame_v2_hw() hisi_sas: add v2 phy init code hisi_sas: add v2 int init and phy up handler hisi_sas: add v2 phy down handler hisi_sas: add v2 channel interrupt handler hisi_sas: add v2 SATA interrupt handler hisi_sas: add v2 cq interrupt handler hisi_sas: add v2 path to send ssp frame hisi_sas: add v2 code to send smp command hisi_sas: add v2 code for itct setup and free hisi_sas: add v2 path to send ATA command hisi_sas: add v2 slot error handler hisi_sas: add v2 tmf functions hisi_sas: update driver version to 1.1 .../devicetree/bindings/scsi/hisilicon-sas.txt | 21 +- drivers/scsi/hisi_sas/Kconfig | 1 + drivers/scsi/hisi_sas/Makefile | 2 +- drivers/scsi/hisi_sas/hisi_sas.h | 39 +- drivers/scsi/hisi_sas/hisi_sas_main.c | 36 +- drivers/scsi/hisi_sas/hisi_sas_v1_hw.c | 20 +- drivers/scsi/hisi_sas/hisi_sas_v2_hw.c | 2205 ++++++++++++++++++++ 7 files changed, 2278 insertions(+), 46 deletions(-) create mode 100644 drivers/scsi/hisi_sas/hisi_sas_v2_hw.c Reviewed-by: Hannes Reinecke -- 1.9.1
