[PATCH v2 00/23] HiSilicon SAS v2 hw support

From: John Garry This patchset introduces support for the HiSi SAS v2 hw. 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 fe

[PATCH v2 01/23] devicetree: bindings: hisi_sas: add v2 HW bindings

From: John Garry Add the dt bindings for HiSi SAS controller v2 HW. The main difference in the controller from dt perspective is interrupts. The v2 controller does not have dedicated fatal and broadcast interrupts - they are multiplexed on the channel interrupt. Each SAS v2 controller can issue
