SCSI misc on 20160113

Browse Source 
This pull 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).

* 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];
