To reduce the number of lines of data in the OMAP portion of the Linux
code base, subsequent patches will remove the lists of hwmod
interconnect links from the static hwmod data.  These lists will be
built dynamically during boot.  To ease this transition, this patch
centralizes the way that interconnect links are iterated into a single
function, _fetch_next_ocp_if().

Most IP blocks on the OMAP SoC have an interconnect link that is
intended to be used by the MPU to communicate with the IP block.
Several parts of the hwmod code need to be able to identify this link.
Currently, this is open-coded.  However, future patches will change
the way that interconnect links are represented and will make
identifying the link more complex.  So to avoid code duplication, this
patch centralizes the MPU port link identification code into a new
function, _find_mpu_rt_port().

Extend the OCP_* register offsets in the struct
omap_hwmod_class_sysconfig to 32 bits.  This is required to add the
OMAP4+ GPU hwmod, which uses OCP_* register offsets larger than 16
bits.

Another possible solution may be to simply add a single 16 bit offset
field in this structure, and to add code to factor that offset into
all OCP_* register accesses.  This would save some memory, since
almost no modules need 32 bit offsets.

Some hwmods were commented out from the OMAP4 data, under the theory
that they shouldn't be added until drivers were ready.  But part of
the utility of the hwmod code is that it can reset and properly
initialize IP blocks that have no drivers associated with them.
Rather than commenting the links in the future hwmod data conversion
patches, discussing this with Benoit, it seems best to simply
uncomment them now.

One of the OMAP4 links was missing OCP_USER flags, since it was only
used by the DSP initiator, and we did not have an OCP_USER_DSP flag.
Future patches will switch the hwmod code and data to register
interfaces, rather than hwmods, and it will be mandatory for all
interfaces to have at least one user bit set.  This patch resolves the
issue by adding OCP_USER_DSP and marking the DSP-IVA interface
appropriately.

Commit 407a6888 ("OMAP4: hwmod data:
Add AESS, McPDM, bandgap, counter_32k, MMC, KBD, ISS & IPU") adds a
hwmod for the bandgap die temperature sensor IP block.  This IP block
has no interconnect port or firewall region, nor does it have an
independent register space or OCP control registers.  Its registers
are embedded in the System Control Module (SCM) IP block.  So it
appears that the bandgap device should be created by the SCM driver.

Change the way that hardreset lines are handled by the hwmod code.
Hardreset lines are generally associated with initiator IP blocks.
Prior to this change, the hwmod code expected to control hardreset
lines itself, asserting them on shutdown and deasserting them upon
enable.  But driver authors inside TI have commented to us that their
drivers require direct control over these lines.  Unfortunately, these
drivers haven't been posted publicly yet, so it's hard to determine
exactly what is needed, a priori.  This change attempts to set forth
some reasonable semantics that should be an improvement over the
current code.

The semantics implemented by this patch are as follows:

- If the hwmod is not marked with HWMOD_INIT_NO_RESET, then assert all
  associated hardreset lines during IP block setup.  This is intended
  to place the IP blocks into a known state that will not interfere
  with other devices during kernel boot.

- IP blocks with hardreset lines will not be automatically enabled or
  idled during setup.  Instead, they will be left in the INITIALIZED
  state.

- When the hwmod code is asked to enable, idle, or shutdown an IP
  block with asserted hardreset lines, the hwmod code will do nothing.
  The driver integration code must do the remaining work needed to
  control these IP blocks.  Once this driver integration code is posted
  to the lists, hopefully we can consolidate it and move it inside the
  hwmod code.

Custom reset functions for IP blocks with hardreset lines still should
be supported and are strongly endorsed.  It is intended that every
subsystem with hardreset lines should have a custom reset function
that can place their subsystem into quiescent idle with the hardreset
lines deasserted.

This reverts most of commit 5365efbe
("OMAP: hwmod: Add hardreset management support").  Later code
reorganizations caused the sequencing of the code from this patch to
be changed, anyway.

Revise the IP block reset process.  This patch ensures that the
OCP_SYSCONFIG registers are reloaded after a custom reset.  Since
OCP_SYSCONFIG bits are cleared during reset, they should be
reprogrammed unless the IP block is being left in reset.  (The only IP
blocks that are left in reset are IP blocks with hardreset lines and
no custom reset function.)  If the IP block is left in reset, then it
is inaccessible to the MPU, and an access to the OCP_SYSCONFIG
register will cause an abort.

This version incorporates comments from Omar Ramirez Luna
<omar.ramirez@ti.com> to skip the OCP_SYSCONFIG access after asserting
hardreset lines.  This allows the MMU (IOMMU) IP block, which has
both hardreset lines and an OCP_SYSCONFIG register.

Also, ignore _ocp_softreset() errors if the IP block doesn't include a
softreset bit.  This is needed since a subsequent patch will start
taking the return value of the _reset() function seriously.

Remove the pseudo-hwmods associated with hardreset lines from the
OMAP4 data file.  Future patches will convert this data to register
hwmods by interfaces, rather than registering hwmods directly.  The
pseudo-hwmods aren't associated with any interfaces, so this will
create a problem.

After this change, the hwmod code will reset processor IPs at the
hwmod level, rather than by individual hardreset lines.  So, for
example, if the IVA device driver code wishes to place one of the
sequencer cores into reset, while leaving the other active, it must do
so itself by calling the appropriate PRM functions.

This patch will cause a change in the initialization behavior of the
DSP, IVA, and IPU.

Parts of the hwmod code test to see if a module has one and only one
hardreset line before taking an action.  It seems more appropriate
to control all hardreset lines associated with a hwmod, not just one.

It so happens that with the current hwmod data, this patch will not
change any behavior, since hwmods with hardreset lines have only one
hardreset line associated with them, and 'pseudo-hwmods' are used to
handle the other hardreset lines.  But future hwmod data patches to
remove the pseudo-hwmods will change this.

The clocks for all DSS slave interfaces were recently changed to "dss_ick" on
OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface
previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and
hence the OCPIF_SWSUP_IDLE flag was needed.

Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is
now "dss_ick".  This allows the PRCM hardware to autoidle the VENC
interface clocks when they are not active, rather than relying on the
software to do it, which can keep the interface clocks active
unnecessarily.

Due to HW limitation, some IPs should not be accessed just after a
softreset. Since the current hwmod sequence is accessing the sysconfig
register just after the reset, it might lead to OCP bus error in
that case.

Add a new field in the sysconfig structure to specify a delay in usecs
needed after doing a softreset.

In the case of the ISS and FDIF modules, the L3 OCP port will be
disconnected upon a SW reset. That issue was confirmed with HW simulation
and an errata should be available soon. The HW recommendation to avoid
that is to wait for 100 OCP clk cycles, before accessing the IP.

Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
so a 1 usec delay is needed. Add an x2 margin to be safe.

I have a new optimized x86 "strncpy_from_user()" that will use these
same helper functions for all the same reasons the name lookup code uses
them.  This is preparation for that.

This moves them into an architecture-specific header file.  It's
architecture-specific for two reasons:

 - some of the functions are likely to want architecture-specific
   implementations.  Even if the current code happens to be "generic" in
   the sense that it should work on any little-endian machine, it's
   likely that the "multiply by a big constant and shift" implementation
   is less than optimal for an architecture that has a guaranteed fast
   bit count instruction, for example.

 - I expect that if architectures like sparc want to start playing
   around with this, we'll need to abstract out a few more details (in
   particular the actual unaligned accesses).  So we're likely to have
   more architecture-specific stuff if non-x86 architectures start using
   this.

   (and if it turns out that non-x86 architectures don't start using
   this, then having it in an architecture-specific header is still the
   right thing to do, of course)

The reason we are dying is b/c the call acpi_get_override_irq() is used,
which returns the polarity and trigger for the IRQs. That function calls
mp_find_ioapics to get the 'struct ioapic' structure - which along with the
mp_irq[x] is used to figure out the default values and the polarity/trigger
overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled
with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the
mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt.

The proper fix for this is going in v3.5 and adds an x86_io_apic_ops
struct so that platforms can override it. But for v3.4 lets carry this
work-around. This patch does that by providing a slightly different variant
of the fake IOAPIC entries.

In the SYSC_TYPE1_XXX_MASK configuration, SYSC_XXX_SHIFT macro
is used which is not defined anywhere in the kernel.
Until now the build was going through successfully, since it
is not being used anywhere in kernel.

This bug got introduced by the commit
358f0e63 ("OMAP3: hwmod: support
to specify the offset position of various SYSCONFIG register bits.")

omap_hwmod_softreset() does not seem to wait for reset status
after doing a softreset. Make it use _ocp_softreset() instead
which does this correctly.
