SCSI misc on 20161213

Browse Source 
This update includes the usual round of major driver updates (ncr5380,
 lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).  There's also
 an assortment of minor fixes, mostly in error legs or other not very
 user visible stuff.  The major change is the pci_alloc_irq_vectors
 replacement for the old pci_msix_.. calls; this effectively makes IRQ
 mapping generic for the drivers and allows blk_mq to use the
 information.

contain a phandle reference to UFS PHY node.
Required properties:
- compatible : compatible list, contains "qcom,ufs-phy-qmp-20nm"
or "qcom,ufs-phy-qmp-14nm" according to the relevant phy in use.
- compatible : compatible list, contains one of the following -
"qcom,ufs-phy-qmp-20nm" for 20nm ufs phy,
"qcom,ufs-phy-qmp-14nm" for legacy 14nm ufs phy,
"qcom,msm8996-ufs-phy-qmp-14nm" for 14nm ufs phy
present on MSM8996 chipset.
- reg : should contain PHY register address space (mandatory),
- reg-names : indicates various resources passed to driver (via reg proptery) by name.
Required "reg-names" is "phy_mem".

This is a driver for the old NCR 53c80 series of SCSI controllers
on boards using PIO. Most boards such as the Trantor T130 fit this
category, along with a large number of ISA 8bit controllers shipped
for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
you should select the specific driver for that card rather than
generic 5380 support.
It is explained in section 3.8 of the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. If it doesn't work out
of the box, you may have to change some settings in
<file:drivers/scsi/g_NCR5380.h>.
This is a driver for old ISA card SCSI controllers based on a
NCR 5380, 53C80, 53C400, 53C400A, or DTC 436 device.
