Anton Vorontsov 0b51b02edf [POWERPC] QE: implement qe_muram_offset
qe_muram_offset is the reverse of the qe_muram_addr, will be
used for the Freescale QE USB Host Controller driver.

This patch also moves qe_muram_addr into the qe.h header, plus
adds __iomem hints to use with sparse.

Anton Vorontsov acaa7aa30a [POWERPC] fsl_lbc: implement few UPM routines
Freescale UPM can be used to adjust localbus timings or to generate
orbitrary, pre-programmed "patterns" on the external Localbus signals.
This patch implements few routines so drivers could work with UPMs in
safe and generic manner.

So far there is just one user of these routines: Freescale UPM NAND
driver.

Similarly to what is done for PQ1-based platforms, this patch resets the

Dale Farnsworth a0916bd64a [POWERPC] mv643xx_eth: Prepare to support multiple silicon blocks
The mv643xx_eth driver is being modified to support multiple instances
of the ethernet silicon block on the same platform.  Each block contains
a single register bank containing the registers for up to three ports
interleaved within that bank.  This patch updates the PowerPC OF to
platform_device glue code to support multiple silicon blocks, each
with up to three ethernet ports.  The main difference is that we now
allow multiple mv64x60_shared platform_devices to be registered and
we provide each port platform_device with a pointer to its associated
shared platform_device.  The pointer will not be used until the
mv643xx_eth driver changes are committed.

Since the arch/powerpc PCI subsystem now does a complete re-assignment of
the resources, we can move from the unconditional PCIe PHY reset to the

with some Atheros PCIe boards and some HP FPGA PCIe designs.

Anatolij Gustschin 7ea6fd7e2d [POWERPC] Fix Oops with TQM5200 on TQM5200
The "bestcomm-core" driver defines its of_match table as follows

static struct of_device_id mpc52xx_bcom_of_match[] = {
	{ .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", },
	{ .type = "dma-controller", .compatible = "mpc5200-bestcomm", },
	{},
};

so while registering the driver, the driver's probe function won't be
called, because the device tree node doesn't have a device_type
property.  Thus the driver's bcom_engine structure won't be allocated.
Referencing this structure later causes observed Oops.

Checking bcom_eng pointer for NULL before referencing data pointed
by it prevents oopsing, but fec driver still doesn't work (because
of the lost bestcomm match and resulted task allocation failure).
Actually the compatible property exists and should match and so
the fec driver should work.

This removes .type = "dma-controller" from the bestcomm driver's
mpc52xx_bcom_of_match table to solve the problem.

Julia Lawall b1725c9319 [POWERPC] arch/powerpc/sysdev: Add missing of_node_put
The functions of_find_compatible_node and of_find_node_by_type both
call of_node_get on their result.  So any error handling code
thereafter should call of_node_put(np).  This is taken care of in the
case where there is a goto out, but not when there is a direct return.

The function irq_alloc_host puts np into the returned structure, which is
stored in the global variable mpc8xx_pic_host, so the reference count
should be set for the lifetime of that variable.  The current solution ups
the reference count again in the argument to irq_alloc_host so that it can
be decremented on the way out.  This seems a bit unnecessary, and also
doesn't work in the case where irq_alloc_host fails, because then the
reference count only goes does by one, whereas it should go down by two.  A
better solution is to not increment the reference count in the argument to
irq_alloc_host and only decrement it on the way out in an error case.

The problem was found using the following semantic match.

David Gibson 22258fa40e [POWERPC] Enable RTC for Ebony and Walnut (v2)
This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
	http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

Olof Johansson d87bf3bed7 [POWERPC] pasemi: Distribute interrupts evenly across cpus
By default the OpenPIC on PWRficient will bias to one core (since that
will improve changes of the other core being able to stay idle/powered
down). However, this conflicts with most irq load balancing schemes,
since setting an interrupt to be delivered to either core doesn't really
result in the load being shared. It also doesn't work well with the
soft irq disable feature of PPC, since EE will stay on until the first
interrupt is taken while soft disabled.

Set the gconf0 config bit that enables even distribution of interrupts
among the two cores.

Olof Johansson f365355e65 [POWERPC] pasemi: Implement NMI support
Some PWRficient-based boards have a NMI button that's wired up to a GPIO
as interrupt source. By configuring the openpic accordingly, these get
delivered as a machine check with high priority, instead of as an external
interrupt.

The device tree contains a property "nmi-source" in the openpic node
for these systems, and it's the (hwirq) source for the input.

Also, for these interrupts, the IACK is read from another register than
the regular (MCACK instead), but they are EOI'd as usual. So implement
said function for the mpic driver.

Finally, move a couple of external function defines to include/ instead
of local under sysdev. Being able to mask/unmask and eoi directly saves
us from setting up a dummy irq handler that will never be called.

cascade, just like othe ppc platforms do. With current implementation we have
additional redirection for irq handler and we call generic_handle_irq twice

This causes Ingo's realtime support patch to stop working on 4xx.

Not sure of any other possible problems though, but with
set_irq_chained_handler() we can abolish "struct irqaction cascade" from the
chip descriptor and call generic_handle_irq() once, directly for cascade irq.

Valentine Barshak c80905637e [POWERPC] 4xx: make UIC use generic level irq handler
This patch makes PowerPC 4xx UIC use generic level irq handler instead
of a custom handle_uic_irq() function. We ack only edge irqs in mask_ack
callback, since acking a level irq on UIC has no effect if the interrupt
is still asserted by the device, even if the interrupt is already masked.
So, to really de-assert the interrupt we need to de-assert the external
source first *and* ack it on UIC then. The handle_level_irq() function
masks and ack's the interrupt with mask_ack callback prior to calling
the actual ISR and unmasks it at the end. So, to use it with UIC interrupts
we need to ack level irqs in the unmask callback instead, after the ISR
has de-asserted the external interrupt source. Even if we ack the interrupt
that we didn't handle (unmask/ack it at the end of the handler, while
next irq is already pending) it will not de-assert the irq, untill we
de-assert its exteral source.

Benjamin Herrenschmidt a2d2e1ec07 [POWERPC] 4xx: PLB to PCI Express support
This adds to the previous 2 patches the support for the 4xx PCI Express
cells as found in the 440SPe revA, revB and 405EX.

Unfortunately, due to significant differences between these, and other
interesting "features" of those pieces of HW, the code isn't as simple
as it is for PCI and PCI-X and some of the functions differ significantly
between the 3 implementations. Thus, not only this code can only support
those 3 implementations for now and will refuse to operate on any other,
but there are added ifdef's to avoid the bloat of building a fairly large
amount of code on platforms that don't need it.

Also, this code currently only supports fully initializing root complex
nodes, not endpoint. Some more code will have to be lifted from the
arch/ppc implementation to add the endpoint support, though it's mostly
differences in memory mapping, and the question on how to represent
endpoint mode PCI in the device-tree is thus open.

Many thanks to Stefan Roese for testing & fixing up the 405EX bits !

Olof Johansson 38958dd911 [POWERPC] pasemi: Implement MSI support
Implement MSI support for PA Semi PWRficient platforms. MSI is done
through a special range of sources on the openpic controller, and they're
unfortunately breaking the usual concepts of how sources are programmed:

* The source is calculated as 512 + the value written into the MSI
  register
* The vector for this source is added to the source and reported
  through IACK

This means that for simplicity, it makes much more sense to just set the
vector to 0 for the source, since that's really the vector we expect to
see from IACK.

Also, the affinity/priority registers will affect 16 sources at a
time. To avoid most (simple) users from being limited by this, allocate
16 sources per device but use only one. This means that there's a total
of 32 sources.

If we get usage scenarions that need more sources, the allocator should
probably be revised to take an alignment argument and size, not just do
natural alignment.

Finally, since I'm already touching the MPIC names on pasemi, rename
the base one from the somewhat odd " PAS-OPIC  " to "PASEMI-OPIC".

Michael Ellerman 83f34df4e7 Add dcr_host_t.base in dcr_read()/dcr_write()
Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we
can save them the trouble and do it in dcr_read()/dcr_write().

As some background to why we just went through all this jiggery-pokery,
benh sayeth:

 Initially the goal of the dcr_read/dcr_write routines was to operate like
 mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx
 hardware, indirect DCR access is a pain (goes through a table of
 instructions) and it's useful to have the compiler resolve an absolute DCR
 inline.

 We decided that wasn't worth the API bastardisation since most places
 where absolute DCR values are used are low level 4xx-only code which may
 as well continue using mfdcr/mtdcr, while the new API is designed for
 device "instances" that can exist on 4xx and Axon type platforms and may
 be located at variable DCR offsets.

Anton Vorontsov cccd21027c [POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascading
set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.

To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.

Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).

qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.

Timur Tabi 6b0b594bb8 [POWERPC] qe: miscellaneous code improvements and fixes to the QE library
This patch makes numerous miscellaneous code improvements to the QE library.

1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type()
   (every caller of ucc_init_guemr() also calls ucc_set_type()).  Modify all
   callers of ucc_set_type() accordingly.

2. Remove the unused enum ucc_pram_initial_offset.

3. Refactor qe_setbrg(), also implement work-around for errata QE_General4.

4. Several printk() calls were missing the terminating \n.

5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where
   appropriate.

6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed
   with the wrong value.

7. Add the protocol type to struct us_info and updated ucc_slow_init() to
   use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED.

8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx()

9. Add several macros in qe.h (mostly for slow UCC support, but also to
   standardize some naming convention) and remove several unused macros.

10. Update ucc_geth.c to use the new macros.

11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol
    to use when initializing the UCC in ucc_slow_init().

12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since
    these are the real names of the registers.

13. Use the setbits, clrbits, and clrsetbits where appropriate.

14. Refactor ucc_set_qe_mux_rxtx().

15. Remove all instances of 'volatile'.

16. Simplify get_cmxucr_reg();

17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[].

18. Updated struct ucc_geth because struct ucc_fast is not padded any more.

Scott Wood 15f8c604a7 [POWERPC] cpm: Describe multi-user ram in its own device node.
The way the current CPM binding describes available multi-user (a.k.a.
dual-ported) RAM doesn't work well when there are multiple free regions,
and it doesn't work at all if the region doesn't begin at the start of
the muram area (as the hardware needs to be programmed with offsets into
this area).  The latter situation can happen with SMC UARTs on CPM2, as its
parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
support moving it.

It is now described with a muram node, similar to QE.  The current CPM
binding is sufficiently recent (i.e. never appeared in an official release)
that compatibility with existing device trees is not an issue.

The code supporting the new binding is shared between cpm1 and cpm2, rather
than remain separated.  QE should be able to use this code as well, once
minor fixes are made to its device trees.

Scott Wood e631ae3b16 [POWERPC] Introduce new CPM device bindings.
This introduces a new device binding for the CPM and other devices on
these boards.  Some of the changes include:

1. Proper namespace scoping for Freescale compatibles and properties.

2. Use compatible rather than things like device_type and model
to determine which particular variant of a device is present.

3. Give the drivers the relevant CPM command word directly, rather than
requiring it to have a lookup table based on device-id, SCC v. SMC, and
CPM version.

4. Specify the CPCR and the usable DPRAM region in the CPM's reg property.

Boards that do not require the legacy bindings should select
CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once
all existing boards are converted and tested, the config option can
become default y to prevent new boards from using the old model.  Once
arch/ppc is gone, the config option can be removed altogether.

Dale Farnsworth 9b41fcb0eb [POWERPC] Add Marvell mv64x60 udbg putc/getc functions
Commit 69331af, "Fixes and cleanups for earlyprintk aka boot console",
resulted in printk output prior to the initialization of the mpsc
console driver not being printed.  That commit causes the mpsc's
CON_PRINTBUFFER flag to be cleared since udbg should have printed
the previous output.

I guess we can no longer ignore udbg. :)

This patch provides udbg_putc() and udbg_getc() functions for the
Marvell mv64x60 chips. These functions are enabled if an mv64x60
port is to be used as the console as determined from the device tree.

Olof Johansson 0d72ba930c [POWERPC] Add workaround for MPICs with broken register reads
Some versions of PWRficient 1682M have an interrupt controller in which
the first register in each pair for interrupt sources doesn't always
read with the right polarity/sense values.

To work around this, keep a software copy of the register instead.  Since
it's not modified from the mpic itself, it's a feasible solution.  Still,
keep it under a config option to avoid wasting memory on other platforms.

David Gibson 553fdff633 [POWERPC] Improve robustness of the UIC cascade handler
At present the cascade interrupt handler for the UIC (interrupt
controller on 4xx embedded chips) will misbehave badly if it is called
spuriously - that is if the handler is invoked when no interrupts are
asserted in the child UIC.

Although spurious interrupts shouldn't happen, it's good to behave
robustly if they do.  This patch does so by checking for and ignoring
spurious interrupts.

David Gibson 868afce21f [POWERPC] Fix irq flow handler for 4xx UIC
At present the driver for the UIC (the embedded interrupt controller
in 4xx chips) uses the handle_level_irq() flow handler.  It turns out
this does not correctly handle level triggered interrupts on the UIC.

Specifically, acknowledging an irq on the UIC (i.e. clearing the
relevant bit in UIC_SR) will have no effect for a level interrupt
which is still asserted by the external device, even if the irq is
already masked.  Therefore, unlike handle_level_irq() we must ack the
interrupt after invoking the ISR (which should cause the device to
stop asserting the irq) instead of acking it when we mask it, before
the ISR.

This patch implements this change, in a new handle_uic_irq(), a
customised irq flow handler for the UIC.  For edge triggered
interrupts, handle_uic_irq() still uses the old flow - we must ack
edge triggered interrupt before the ISR not after, or we could miss a
second event which occurred between invoking the ISR and acking the
irq.

Benjamin Herrenschmidt 7fd7218610 [POWERPC] MPIC protected sources
Some HW platforms, such as the new cell blades, requires some MPIC sources
to be left alone by the operating system. This implements support for
a "protected-sources" property in the mpic controller node containing a list
of source numbers to be protected against operating system interference.

For those interested in the gory details, the MPIC on the southbridge of
those blades has some of the processor outputs routed to the cell, and

in the GA product for routing some of the southbridge error interrupts
to the service processor which implements some of the RAS stuff, such
as checkstopping when fatal errors occurs before they can propagate.

Maxim Shchetynin dbdf04c401 [CELL] driver for DDR2 memory on AXON
The Axon bridge chip used on new Cell/B.E. based blade servers
comes with a DDR2 memory controller that can be used to
attach cheap memory modules, as opposed to the high-speed
XDR memory that is used by the CPU itself.

Since the memory controller does not participate in the
cache coherency protocol, we can not use the memory direcly
for Linux applications, but by providing a block device
it can be used for swap space, temporary file storage and
through the use of the direct_access block device operation
for mapping into user addresses, when it is mounted with
an appropriate file system.

Christian Krafft 813f90728e [CELL] pmi: remove support for mutiple devices.
The pmi driver got simplified by removing support for multiple devices.
As there is no more than one pmi device per maschine, there is no need to
specify the device for listening and sending messages.

This way the caller (cbe_cpufreq) doesn't need to scan the device tree.
When registering the handler on a board without a pmi
interface, pmi.c will just return -ENODEV.

The patch that fixed the breakage of cell_defconfig has been
broken out of the earlier version of this patch. So this is
the version that applies cleanly on top of it.

Andy Fleming 7132ab7f6e Fix RGMII-ID handling in gianfar
The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay.  So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII.  This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.

Vitaly Bordug 80128ff79d [POWERPC] 8xx: mpc885ads pcmcia support
Adds support for PowerQuicc on-chip PCMCIA.  The driver is implemented as
of_device, so only arch/powerpc stuff is capable to use it, which now implies
only mpc885ads reference board.

To cope with the code that should be hooked inside driver, but is really board
specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds
necessary function pointers that are filled in the BSP code.

Kumar Gala 476f5779b7 [POWERPC] 86xx: Workaround PCI_PRIMARY_BUS usage
The Freescale PCI-e controllers have an issue in that they use the
PCI_PRIMARY_BUS register in the virtual P2P bridge to determine which
bus number to match on when generating a type 0 config cycle.  The
issue is if we are renumbering bus numbers to match Linux we will try
setting the PCI_PRIMARY_BUS and will not know which bus number to use
for generating type 0 config cycles.  We surpress writing the register
in the P2P bridge and always keep it at zero.

In the future when proper PCI domain support is working we should be
able to remove this.

The generic PCI config ops indirect support for ppc32 covers only two
cases (implicit vs explicit) type 0/1 config cycles via set_cfg_type.
Added a indirect_type bit mask to handle other variants.

Added support for PCI-e extended registers and moved the cfg_type
handling into the bit mask for ARCH=powerpc.  We can also use this to
handle indirect quirks.
