Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "This includes driver updates from the usual suspects (bfa, arcmsr, scsi_dh_alua, lpfc, storvsc, cxlflash). The major change is the addition of the hisi_sas driver, which is an ARM platform device for SAS. The other change of note is an enormous style transformation to the atp870u driver (which is our worst written SCSI driver)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (169 commits) cxlflash: Enable device id for future IBM CXL adapter cxlflash: Resolve oops in wait_port_offline cxlflash: Fix to resolve cmd leak after host reset cxlflash: Removed driver date print cxlflash: Fix to avoid virtual LUN failover failure cxlflash: Fix to escalate LINK_RESET also on port 1 storvsc: Tighten up the interrupt path storvsc: Refactor the code in storvsc_channel_init() storvsc: Properly support Fibre Channel devices storvsc: Fix a bug in the layout of the hv_fc_wwn_packet mvsas: Add SGPIO support to Marvell 94xx mpt3sas: A correction in unmap_resources hpsa: Add box and bay information for enclosure devices hpsa: Change SAS transport devices to bus 0. hpsa: fix path_info_show cciss: print max outstanding commands as a hex value scsi_debug: Increase the reported optimal transfer length lpfc: Update version to 11.0.0.10 for upstream patch set lpfc: Use kzalloc instead of kmalloc lpfc: Delete unnecessary checks before the function call "mempool_destroy" ...

+* HiSilicon SAS controller
+
+The HiSilicon SAS controller supports SAS/SATA.
+
+Main node required properties:
+ - compatible : value should be as follows:
+ (a) "hisilicon,hip05-sas-v1" for v1 hw in hip05 chipset
+ - sas-addr : array of 8 bytes for host SAS address
+ - reg : Address and length of the SAS register
+ - hisilicon,sas-syscon: phandle of syscon used for sas control
+ - ctrl-reset-reg : offset to controller reset register in ctrl reg
+ - ctrl-reset-sts-reg : offset to controller reset status register in ctrl reg
+ - ctrl-clock-ena-reg : offset to controller clock enable register in ctrl reg
+ - queue-count : number of delivery and completion queues in the controller
+ - phy-count : number of phys accessible by the controller
+ - interrupts : Interrupts for phys, completion queues, and fatal
+ sources; the interrupts are ordered in 3 groups, as follows:
+ - Phy interrupts
+ - Completion queue interrupts
+ - Fatal interrupts
+ Phy interrupts : Each phy has 3 interrupt sources:
+ - broadcast
+ - phyup
+ - abnormal
+ The phy interrupts are ordered into groups of 3 per phy
+ (broadcast, phyup, and abnormal) in increasing order.
+ Completion queue interrupts : each completion queue has 1
+ interrupt source.
+ The interrupts are ordered in increasing order.
+ Fatal interrupts : the fatal interrupts are ordered as follows:
+ - ECC
+ - AXI bus
+
+Example:
+ sas0: sas@c1000000 {
+ compatible = "hisilicon,hip05-sas-v1";
+ sas-addr = [50 01 88 20 16 00 00 0a];
