[PATCH 0/6 v4] Few more patches for Kumar's powerpc.git

[Anton Vorontsov]

Hi Kumar,

Here is the fourth version. Old one started to cause non trivial merge
conflicts.

Also, I re-exported the gtm_timer structure, so drivers could actually
use its irq member.

Thanks.

[PATCH 1/6] [POWERPC] sysdev: implement FSL GTM support

[Anton Vorontsov]

GTM stands for General-purpose Timers Module and able to generate
timer{1,2,3,4} interrupts. These timers are used by the drivers that
need time precise interrupts (like for USB transactions scheduling for
the Freescale USB Host controller as found in some QE and CPM chips),
or these timers could be used as wakeup events from the CPU deep-sleep
mode.

Things unimplemented:
1. Cascaded (32 bit) timers (1-2, 3-4).
   This is straightforward to implement when needed, two timers should
   be marked as "requested" and configured as appropriate.
2. Super-cascaded (64 bit) timers (1-2-3-4).
   This is also straightforward to implement when needed, all timers
   should be marked as "requested" and configured as appropriate.

[PATCH 2/6] [POWERPC] QE: add support for QE USB clocks routing

[Anton Vorontsov]

This patch adds a function to the qe_lib to setup QE USB clocks routing.
To setup clocks safely, cmxgcr register needs locking, so I just reused
ucc_lock since it was used only to protect cmxgcr.

The idea behind placing clocks routing functions into the qe_lib is that
later we'll hopefully switch to the generic Linux Clock API, thus, for
example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs.

This patch also fixes QE_USB_RESTART_TX command definition in the qe.h.

[PATCH 3/6] [POWERPC] QE: prepare QE PIO code for GPIO LIB support

[Anton Vorontsov]

- split and export __par_io_config_pin() out of par_io_config_pin(), so we
  could use the prefixed version with GPIO LIB API;
- rename struct port_regs to qe_pio_regs, and place it into qe.h;
- rename #define NUM_OF_PINS to QE_PIO_PINS, and place it into qe.h.

[PATCH 5/6] [POWERPC] 83xx: new board support: MPC8360E-RDK

[Anton Vorontsov]

This is patch adds board file, device tree, and defconfig for the new
board, made by Freescale Semiconductor Inc. and Logic Product Development.

Currently supported:
1. UEC{1,2,7,4};
2. I2C;
3. SPI;
4. NS16550 serial;
5. PCI and miniPCI;
6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85;
7. Graphics controller, Fujitsu MB86277.

Not supported in this patch:
1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM NAND driver);
2. FHCI USB (supported with FHCI driver).
3. QE Serial UCCs (tested to not work with ucc_uart driver, reason
   unknown, yet);
4. ADC AD7843 (tested to work, but support via device tree depends on
   major SPI rework, GPIO API, etc);

I think this change will break a number of boards, because a lot of them do this:

	if ((np = of_find_node_by_name(NULL, "par_io")) != NULL) {
		par_io_init(np);

So if you're going to change the par_io nodes, you need to change the code as well.

A patch that changes the documentation should also change the code.  And if
you're code changes the device tree, it should also maintain compatibility for
older device trees.

You can't just delete the par_io documentation without updating the code and
planning for feature removal.  Almost all of the existing code out there for QE
boards expects a par_io node, and the device trees still have them.

Do we need to do "!!"?  I thought as long as the result was non-zero, it didn't
matter what the actual value is.  "!!" converts non-zero to 1.

Memory leak here.  If of_mm_gpiochip_add() fails or if the 2nd call to kzalloc()
fails, the already-allocated qe_gc objects won't be released.

Well, I'm indeed removing [further] support for the par_io nodes,
overwriting it with gpio nodes. That way we'll stop new use cases of
these nodes.

Eventually I plan to adjust the existing code/device trees accordingly.
If you think that code should be adjusted at the same time as
documentation, I'm fine with it as well. I'll just add new documentation
instead of replacing the old.

Yup, exactly. Old device tree still use them, but don't we want to get
rid of this? If so, we should remove documentation, or someone will
use it for the new device trees. ;-)

Just checked with the Documentation/gpio.txt... yup we don't need this.
"The values are boolean, zero for low, nonzero for high."

Yes, please.

It should still be documented, but marked as deprecated.  The documentation can
be removed only when all the DTS files *and* the code are scrubbed of those
kinds of nodes.  And you can't remove backwards compatibility for those from the
code until at least the next major revision of the kernel.

Look at function of_get_mac_address() for an example.  "mac-address" was removed
mid last year, but we still support them.  Try to isolate the code that support
the newer gpio nodes and the  older par_io nodes into one function, and it'll be
easier to deal with.

Where can I find the code for that binding? fsl_upm_nand.c from
http://patchwork.ozlabs.org/linuxppc/patch?q=upm&id=17306 does not parse
OF partitions. Are there any plans to push the fsl_upm_nand driver
upstream? I'm currently implementing NAND support for the TQM8548 and
want to base it on common code.

Thanks,

Wolfgang.

David already pushed UPM NAND driver upstream, but true, it was an "old"
version, i.e. without approved bindings. I'll send the update (inlining
here) if/when these bindings will be applied to the powerpc tree.

On what hardware did you test the NAND-UPM driver? Unfortunately, the
TQM8548 does not support the R/B pin and therefore GPIO support is not
needed but a chip delay. Furthermore some "asm sync" are required when
executing the run pattern:

  static inline int fsl_upm_run_pattern(struct fsl_upm *upm,
                                        void __iomem *io_base, u32 mar)
  {
        int ret = 0, i;
        unsigned long flags;

        spin_lock_irqsave(&fsl_lbc_lock, flags);

        out_be32(&fsl_lbc_regs->mar, mar << (32 - upm->width));

        asm("sync; isync; msync");

        switch (upm->width) {
        case 8:
                out_8(io_base, 0x0);
                break;
        case 16:
                out_be16(io_base, 0x0);
                break;
        case 32:
                out_be32(io_base, 0x0);
                break;
        default:
                ret = -EINVAL;
                break;
        }

        asm("sync; isync; msync");

        spin_unlock_irqrestore(&fsl_lbc_lock, flags);

        return ret;
  }


Is this a known problem with the MPC85xx? How do we handle it?

Too bad you need this. Oh well, you need to discuss property name with
the OF guys, or think out some other way to deliver the chip delay
value.

I did test this driver on MPC8555 and MPC8360 UPMs. They didn't need
these syncs.. quite suspicious syncs, I must say. Maybe you should
check TLB setup, for the UPM NAND it should be non-cacheable and
guarded, IIRC.

I have that. Are you sure about the e500 CPUs. I have not seen any
MPC85xx board in U-Boot or Linux BSP using FSL UPM. Sometimes these
magic sync instructions seem to be needed, e.g., in the MPC8548 manual I
find:

  "Also, an msync assembly instruction must be executed after each I2C
   register read/write access to guarantee in-order execution."

Can somebody (from freescale?) sched some light on that issue?

TIA.

I know this is an example, but would we ever include both compatible strings in
one DTS?  Isn't the norm something like:

"fsl,mpc8360-qe-pario-bank", "fsl,qe-pario-bank";

I.e. specific version, then generic version?

Otherwise, every time we introduce a new QE part, we'll have to update *every*
QE-enabled device tree *and* the QE gpio driver.

Return value should be "u32", not "int".

Per Grant Likely's comments, "fsl,qe-pario-bank" considered as a made up
stuff. MPC8323 is the first QE chip, so every next QE chips should be
compatible.

Though, for fsl,gtm we can't use this, since we really want generic
name.

Nope. If the the QE is compatible with the previous, just write
"fsl,newchip-qe-pario-bank", "fsl,mpc8323-qe-pario-bank".

Btw, the same we do for the 8349 compatible PCI.

In that case, perhaps you should return this:

	return in_be32(&regs->cpdata) & pin_mask ? 1 : 0;

What is the problem with returning (int)(u32 & u32) value?

You've asked to remove "!!" stuff and now purposing exactly the
same... :-?

Technically, a signed int is smaller than an unsigned int, so a value of
0x80000000 won't fit in an 'int'.

> You've asked to remove "!!" stuff and now purposing exactly the
> same... :-?

The !! stuff was because the function was returning a boolean value, so non-zero
== TRUE.  I don't think the return value from 'get' is a technically a boolean,
so I'm assuming that the spec says the return value should be 0 or 1, to reflect
the value of that GPIO pin.

They're of the same size. And because of that, we'll not lose
information, so (int)(0x80000000U) still != 0, it is just negative.

No. The spec indeed says that 0 for low, non-0 for high.

83xx/85xx, QE, CPM2 and CPM1 (no support).
Probably some more old and new chips.

Can you do me a favor and update mpc83xx_defconfig and make sure that  
boots and provide that in a separate patch.  I want to start making  
sure we have whatever features boards need enabled in the  
mpc83xx_defconfig.

Done. This is on top of your current powerpc-next branch (HEAD
at 917f0af9e5a9ce) + applied patches (seems like you forgot to push
out the tree).

Thus mpc83xx_defconfig wasn't updated for a long time, so the
patch isn't readable.

Here is what I enabled manually:

CONFIG_MPC836x_RDK=y

CONFIG_SERIAL_QE=y
^ it doesn't actually work on RDK (unable to receive the data), but I
believe it's QE firmware issue, not linux's driver. So with appropriate
firmware it should work.

CONFIG_FB=y
CONFIG_FB_FOREIGN_ENDIAN=y
^ RDK's framebuffer is little endian.

CONFIG_FB_BOTH_ENDIAN=y
^ also support big-endian framebuffers, e.g. on a PCI

CONFIG_FB_OF=y
^ we use generic driver for the RDK's framebuffer

CONFIG_MTD_CFI_INTELEXT=y
^ to support NOR flash.

CONFIG_MTD_NAND_FSL_UPM=y
^ RDK's device tree doesn't specify nand yet, but as soon as bindings will
be approved, I'll post an update to the dts.

CONFIG_PCI=y
^ Without this FB_OF driver doesn't build (will send a fix soon).

Other stuff in the patch was auto selected/updated.

Can you look at refreshing this against my for-2.6.26 tree (its got an  
updated defconfig)

Or update the mpc83xx_defconfig and than enable what you needed and  
provide a patch of just the things being enabled.

That's an idea. Cherry-picked the defconfig update commit, and here is
the patch on top.

I'm assuming that CONFIG_PCI=n + CONFIG_FB_OF build breakage fix will
be committed prior to this patch. If not, we'll have to enable the
CONFIG_PCI in the defconfig as a separate patch, since it will produce
unreadable changes again. (btw, is there any particular reason why PCI
is disabled?)

[PATCH v3] powerpc/83xx: update mpc83xx_defconfig to support MPC8360E-RDK

[Anton Vorontsov]

This patch updates mpc83xx_defconfig to support MPC8360E-RDK board.

Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>

Completely forgot about BROADCOM_PHY, added now. Without it, only
u-boot initialized BCM PHY will work, second one will unable to
receive/transmit any data.
