[PATCH v5 0/5] omap: mailbox: hwmod support

[PATCH v5 0/5] omap: mailbox: hwmod support

[Omar Ramirez Luna]

Mailbox hwmod support for OMAP 2,3,4.

This was tested on OMAP3 (3430, 3630), minor testing
was made on OMAP4.

No testing on OMAP2 since I don't have the hardware.

Highlights from v5 include the comments received from
previous version v4[1].

[PATCH v5 4/5] OMAP: mailbox: build device using omap_device/omap_hwmod

[Omar Ramirez Luna]

From: Felipe Contreras <felipe.contreras@gmail.com>

Remove static platform_device and resource data within
omap mailbox driver; use the one defined in the hwmod
database along with omap_device framework for device
build and registration.

Add device latency functions to be used, so clock can be
enabled and sysconfig is configured.

Boot testing is a start, but I'm pretty sure that bootup does not use
the mailbox on any of these platforms.  This needs to be tested with
something that actually uses the mailbox.

Do you have any simple standalone tests for mailbox (e.g. without
bridge/syslink) that can be used to so some sanity checking on these
driver changes?

To help in testing, I wrote a simple mailbox loopback test module for
OMAP2/3/4 that I used to do send and receive messages on the MPU.  This
can be used to test the mailbox without any DSP software.

I tested it against l-o master branch and found a couple bugs in the
mailbox driver (patches posted earlier today.)  

With those patches plus my test I can send & receieve a series of
messages on the MPU, which is enough to sanity test the basic sending
and receiving messages on the MPU.

I've tested the master branch, now it's your turn to use this test
module to validate this hmod conversion series.

The test module is available here:

    git://gitorious.org/omap-test/mailbox.git

Note that the current mailbox driver has hard-coded settings for the
receiver of messages.  While this should be configurable at runtime, I'm
not an expert on the mailbox IP so my test module includes a kernel
patch that changes these hard-coded settings of the first mbox (dsp on
OMAP2/3, mailbox-1 on OMAP4) so that my loopback tester will work.

The original entry was unnamed since it is an unique entry and thus does 
not need to be differentiate on this platform.

	{ .irq = 26 + OMAP44XX_IRQ_GIC_START },

Do you really need to have a name here? The strategy being to provide a

I rechecked on OMAP3 (zoom2, zoom3) and OMAP4 (blaze), and
functionality hasn't changed with the hwmod support + Kevin's mbox
test.

On OMAP3, although functionality is ok with this patch set, I noticed
that the interface clock is not being disabled with its corresponding
pm_runtime_disable call. Previously, the driver enabled/disabled the
ick clock on demand, but now the clock stays enabled always (only
affected by the smart-idle feature, I presume).

Should this clock be placed in the main_clk field of omap_hwmod struct
instead of omap_hwmod_ocp_if, I moved it to ocp_if because of the ick
thing, any comment?

It is this way instead of plain platform_get_irq because omap2420 has
two interrupt sources to MPU and mailbox driver uses
platform_get_irq_byname to get the irq number.

This is what I was thinking, except that on OMAP2420 the names are:
+	{ .name = "dsp", .irq = 26, },
+	{ .name = "iva", .irq = 34, },

and on OMAP2430 and OMAP3
+	{ .name = "dsp", .irq = 26, },

so why is it named "mbox" on OMAP4?

If you have to do several platform_get_irq_byname to get this one, I'd 
prefer to get rid of that name for OMAP4. It will make mailbox irq 
consistent with the other hwmods.

Benoit

I'm not very familiar with OMAP4 terminology... but IMHO, I guess
naming it dsp, would imply that this is a mailbox for the dsp, when
the interrupt can be generated by either the M3, dsp, I think even the
IVA can write into it.

I was thinking to standardize the names to be mbox0..mboxN across all
the platforms, reason being that the mailbox also has capabilities to
be used not only by dsp or iva, by using a polling method.

So even if the mailbox in OMAP3 is called "dsp", it has 4 more queues
apart from the 2 used for messaging between arm and dsp, that could be
used even if tidspbridge wasn't there.

Did I get you correctly?

So what's the status of this series? Can the rest of the patches
now be applied on top of the current omap-for-linus or do the names
still need fixing?

I'm going to remove the names for the hwmods with a single irq. And
change the interface clock to be the main_clk, so it can be disabled

I won't resend the patch for OMAP4 hwmod data, as this was send
earlier by Benoit.
