e4a9e1d8f2 staging: vt6655: fix camelcase in bShortSlotTime 
Replace camel case variable bShortSlotTime with snake case variable
short_slot_time. bShortSlotTime is a boolean variable, if true short
slot time is enabled, false not. Short Slot Time reduces the slot time
from 20 microseconds to 9 microseconds, where the slot time is
the maximum theoretical time for a frame to travel a network.

e538e86498 MIPS: asm: pci: define arch-specific 'pci_remap_iospace()' dependent on 'CONFIG_PCI_DRIVERS_GENERIC' 
Some MIPS defconfigs that don't define 'CONFIG_PCI_DRIVERS_GENERIC' but
define 'CONFIG_PCI_DRIVERS_LEGACY' or none of them, can fail when they are
built since definition for 'pci_remap_iospace' is being done in include
file 'arch/mips/include/asm/pci.h' and the specific function implemented
in 'arch/mips/pci/pci-generic.c'. MIPS PCI drivers that don't use generic
PCI core APIs don't really need 'pci_remap_iospace' to be defined at all.
Hence, change definition for 'pci_remap_iospace' to be dependent on the
preprocessor 'CONFIG_PCI_DRIVERS_GENERIC' definition to avoid possible
build problems.

ecd667f5f2 staging: mt7621-dts: properly define 'cpc' and 'mc' nodes 
'cpc' and 'mc' nodes correspond with the MIPS 'Cluster Power Controller'
and 'MIPS Common Device Memory Map' which are present in some MIPS related
boards. There is already bindings documentation for these two located in:
- Documentation/devicetree/bindings/power/mti,mips-cpc.yaml
- Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml

Hence, properly update compatible strings and align nodes with already
mainlined bindings documentation. Also, move their definition to a proper
place since both of them are not related with the palmbus at all.

e0b913816b staging: mt7621-pci: properly adjust base address for the IO window 
The value to adjust in the bridge register RALINK_PCI_IOBASE must take into
account the raw value from DT, not only the translated linux port number.
As long as io_offset is zero, the two are the same, but if you were to use
multiple host bridge in the system, or pick a different bus address in DT,
you can have a nonzero io_offset. At this means to take into account the
bus address which is used to calculate this offset, substracting it from
the IO resource start address.

9f76779f24 MIPS: implement architecture-specific 'pci_remap_iospace()' 
To make PCI IO work we need to properly virtually map IO cpu physical address
and set this virtual address as the address of the first PCI IO port which
is set using function 'set_io_port_base()'.

7c2584faa1 PCI: Allow architecture-specific pci_remap_iospace() 
pci_remap_iospace() was originally meant as an architecture specific helper
but it moved into generic code after all architectures had the same
requirements. MIPS has different requirements so it should not be shared.

The way for doing this will be using a macro 'pci_remap_iospace' defined
for those architectures that need a special treatment. Hence, put core API
function inside preprocesor conditional code for 'pci_remap_iospace'
definition.
