While sh previously had its own debugfs root, there now exists a
common arch_debugfs_dir prototype, so we switch everything over to
that. Presumably once more architectures start making use of this
we'll be able to just kill off the stub kdebugfs wrapper.Signed-off-by: Paul Mundt

This copies the pci_config_lock idea from x86 over, allowing us to kill
off a couple of existing private locks. At the same time, these need to
be converted to raw spinlocks for -rt kernels, so we make that change at
the same time. This should make it easier for future parts to get the
locking right instead of inevitable ending up with lock type mismatches.Signed-off-by: Paul Mundt
-
This gets each port handling its MSTP bit, as well as moving the PHY
clock management in to the clock framework.Signed-off-by: Paul Mundt
-
Some of the existing code is flipping between __raw_xxx() and
pci_{read,write}_reg(). As the latter are just wrappers for the former,
flip over to using them consistently.Signed-off-by: Paul Mundt
-
Presently we error out if a link is disabled and simply drop the port
registration outright. This follows the PPC changes and simply reports on
the link state on boot, leaving the port registered, in order to more
easily deal with hotplug on future parts.Signed-off-by: Paul Mundt

These settings are properly propagated by the hardware already, so
there's no need to bother with them manually.Signed-off-by: Paul Mundt

The SH7786 PCIe is presently unable to enumerate itself in root complex
mode, and has no visibility through either type 0 or type 1 accesses,
despite having a mostly sensible extended config space for each port.
Attempts to generate type 0 or type 1 config cycles result in completer
aborts, so we're ultimately forced to use SuperHyway transactions
instead.As each port has a single port device mapping that resolves for any
PCI_SLOT definition, we simply hijack devfn 0 for the SuperHyway
transaction and bump up the devfn limit.With enumeration of the root complex now possible, we also need to insert
an early fixup to hide the BARs from the kernel. With all of that done,
it's now possible to use the pcieport services with all of the PCIe
ports, which is the first step to power management support.Signed-off-by: Paul Mundt

Previously these IDs were only used by one driver, so there was not much
need for having them generically defined. Now that this will no longer
hold true, move them over.Signed-off-by: Paul Mundt

The spec suggests waiting up to 500ms for the PHY to settle before
testing link state, but practice shows that 100ms is sufficient (this is
the delay value we also use on the other SH-4A PCI controllers, too).
This makes device detection much more reliable, although in the future it
should be a bit faster to simply serialize with a TLP IRQ.Signed-off-by: Paul Mundt

The _remove() routine is flagged __init_or_module, despite only being
used in a __devexit context. As the rest of the driver is already
balanced out with __devinit, switch to __devexit and __devexit_p()
wrapping.Signed-off-by: Paul Mundt

The current probe/remove definitions are split between __init and

Now that the rest of the socket calls are provided through their own
paths, do the same for sys_recvmmsg. It's unlikely we'll ever be able to
kill off the socketcall path, but this at least permits userspace to
gradually begin migrating.Signed-off-by: Paul Mundt
-
Linux kernel already has socket syscalls that can be invoked
without the multiplexing sys_socketcall wrapper.
C library wrappers are ready to use them directly. It needs just
to define the missing syscall numbers and provide the related entries
into the syscalls table, like sh64 aleady does.Signed-off-by: Francesco Rundo

As the help for the config option suggests, this option really shouldn't
be set by default for any recent distribution as it changes the layout
of sysfs. I spotted this while running debian when udev got very
confused by the sysfs layout and failed to create some device nodes.Signed-off-by: Matt Fleming

Now that the resource assignment issues are resolved, we can finally wire
up the small third memory window -- in the future we may reclaim this for
MSI.Signed-off-by: Paul Mundt
-
An IORESOURCE_IO was missing here, which meant that we weren't properly
establishing the I/O window for this particular slot. With this
corrected, cards with I/O BARs have them actually assigned and
accessible.Signed-off-by: Paul Mundt
-
Certain memory windows are only available for 32-bit space, so skip over
these in 29-bit mode. This will severely restrict the amount of memory
that can be mapped, but since a boot loader bug makes booting in 29-bit
mode close to impossible anyways, everything is ok.Signed-off-by: Paul Mundt

This bumps up the low address to match the physical memory windows for
SHwayPCIe transfers. The previous implementation was banking on a 1:1

This was killed off by a simplification patch previously that failed to
take the cpufreq use case in to account, so reinstate the old bounding
logic. The lowest rate bounding on the other hand was broken in that it
never actually got assigned a rate and the best fit rate was instead just
getting lucky based on the ordering of the rate table, fix this up so the
code actually does what it was intended to do originally.Signed-off-by: Paul Mundt
