* [patch-v2.6.39 4/7] OMAP3xxx: hwmod data: Add USBOTG
From: Felipe Balbi @ 2011-02-17 12:41 UTC (permalink / raw)

OMAP3 hwmod data structures are populated for USBOTG with base address,
L3 and L4 interface clocks, IRQs and sysconfig register details.
This is applicable for OMAP3430 amd OMAP3630.
As per OMAP USBOTG specification, need to configure the USBOTG
to smart idle/standby or no idle/standby during data transfer and
force idle/standby when not in use to support retention and offmode.
By setting HWMOD_SWSUP_SIDLE and HWMOD_SWSUP_MSTANDBY flags, framework
will take care of configuring to no idle/standby when module is enabled
and force idle/standby when idled.

As per OMAP USBOTG specification, need to configure the USBOTG

By setting HWMOD_SWSUP_SIDLE and HWMOD_SWSUP_MSTANDBY flags, framework
will take care of configuring to no idle/standby when module is enabled

* [patch-v2.6.39 2/7] arm: omap4: 4430sdp: drop ehci support
From: Felipe Balbi @ 2011-02-17 12:41 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1297946466-9565-1-git-send-email-balbi@ti.com>
From: Anand Gadiyar <gadiyar@ti.com>
Most revisions of the OMAP4 Blaze/SDP platform do not have
the EHCI signals routed by default. The pads are routed
for the alternate HSI functionality instead, and explicit
board modifications are needed to route the signals to
the USB PHY on the board.
Also, turning on the PHY connected to the EHCI port causes
a board reboot during bootup due to an unintended short
on the rails - this affects many initial revisions of the
board, and needs a minor board mod to fix (or as a
workaround, one should not attempt to power on the
USB PHY).
Given that these boards need explicit board mods to even
get EHCI working (separate from the accidental short above),
we should not attempt to enable EHCI by default.
So drop the EHCI support from the board files for the
Blaze/SDP platforms.

* [patch-v2.6.39 1/7] arm: omap4: usb: explicitly configure MUSB pads
From: Felipe Balbi @ 2011-02-17 12:41 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1297946466-9565-1-git-send-email-balbi@ti.com>
From: Anand Gadiyar <gadiyar@ti.com>
Use the mux framework APIs to explicitly configure
the MUSB pads. The MUSB controller in OMAP4 can use
either the old ULPI interface, or the new internal PHY.
Configure the pads accordingly.

Hi Russell,
I tested on SMDKV210(S5PV210) and SMDKC110(S5PC110).
Firstly, looks like suspend working is fine.
But had some problem during resume :( unfortunately, didn't find fundamental
reason of it.
Shortly, the problem is that r14 has always unexpected value, 0x4 on #113
line, "cpy pc, r14" of v7_flush_cache_all.
So happened abort. I will debugging tomorrow then let you know.
As a note, I tested it based on your devel-stable branch.
If missed some stuff, please let me know :)
Thanks.
Best regards,
Kgene.

Right, surely not beacuse of a card, this was a misunderstanding. The issue is
not related to cards but slots. By naming the flag 8_BIT_CAPABLE_SLOT I wanted
to indicate this.

Yep, that's what I meant, too :) Adding the slot capabilities in platform_data.

Hmm, the schematics say no, but I will assume it is a board issue and check
with the manufacturer.
Thanks again!

It's probably a good idea to put some comment in the code to that
effect - people don't generally look at the history when adding new
features. It's probably also a good idea to claim the GPIO for the
PHY power control and ensure that it's set to 'off' mode - that code
can then be a placeholder for the comment.

I have no intention to remove them. If they are done correct they are
not a problem at all. And correct means: tied to the underlying
primary chip.
The shit hits the fan when a chained handler implementation is trying
to be agnostic about the actual underlying primary chip. That won't
ever work and is broken. The only way to make a demux handler agnostic
is to use a regular requested interrupt handler. That's all what I'm
saying.
You have to actually use your brain when implementing a chained
handler. Looking through a bunch of implementations I found stuff,
which is basically a poorly implemented flow handler. Worst example:
fsl_msi_cascade().
ARM ones are mostly sane, but e.g. nmk_gpio_irq_handler() is not
really one which fits your description. It's trying to deal with
different underlying primary chips obviously, which is wrong in the
first place.

It will not break, it will just make the merge a little bit painful for
Tony if we do not re-submit the updated McSPI hwmod data for OMAP4.
Please find below a sample of what the patch should now look like.
BTW, in this case, it will be much better to rename omap2_mcspi_dev_attr
using the same convention as others: <class_name>_dev_attr ->
mcspi_dev_attr.

Benoit

It isn't - what I highlight above is the correct way to deal with
chained interrupts - which is to leave the parent interrupt enabled
_unless_ there is a good reason not to.
It also needs to be symetrical otherwise you unbalance the interrupt
handling such that those interrupts which are downstream of the primary
controller become less likely to be handled, and you end up with some
interrupts being soo pessimistic its untrue. This commonly happens
when people don't think and just throw loop after loop into their
flow handlers.
The last reason for this is to ensure that IRQ handling is *fast* and
*efficient*. Using the standard handlers adds a hell of a lot of
unnecessary overhead which just isn't required.
Look, I put a lot of time and effort into giving ARM an interrupt handling
subsystem which actually _works_ for the hardware that we commonly have,
and I'm not having all that thrown out in the name of 'generalization'.
If genirq can't cope with it, then ARM needs to avoid genirq.
Chained flow handlers are here to stay on ARM.

I see. Maybe we should make this a platform driver then like for example
davinci does.

* [PATCH V4] ST SPEAr: PCIE gadget suppport
From: Pratyush Anand @ 2011-02-17 10:50 UTC (permalink / raw)
To: linux-arm-kernel
This is a configurable gadget. can be configured by configfs interface. Any
IP available at PCIE bus can be programmed to be used by host
controller.It supoorts both INTX and MSI.
By default, gadget is configured for INTX and SYSRAM1 is mapped to BAR0
with size 0x1000
Changes since V3:
- support for multiple instances of such device
- changes to minizie portability issue on 64 bit machine
- unnecessary typecast removed
- sysfs_streq used in place of complex code
Changes since V2:
- driver has been moved from sysfs to configfs
- Documentation/ABI directory has also been updated
- typo error in documenation has been corrected
- clk value is checked after encapsulating by IS_ERR
Changes since V1:
- __iomem added for register addresses
- kerneldoc comment removed whereever not required.
- help node moved from sysfs to documentation/misc-devices
- strict_strtoul used instead of sscanf

+Spear PCIE Gadget Driver:
+
+Author
+=============

+Menuconfig option:
+==========================
+Device Drivers
+ Misc devices
+ PCIE gadget support for SPEAr13XX platform
+purpose
+===========
+This driver has several nodes which can read/written by configfs interface.
+Its main purpose is to configure selected dual mode pcie controller as device
+and then program its various registers to configure it as a particular device
+type. This driver can be used to show spear's pcie device capability.
+
+Description of different nodes:
+=================================
+
+read behavior of nodes:
+------------------------------
+link :gives ltssm status.
+int_type :type of supported interrupt
+no_of_msi :zero if MSI is not enabled by host. A positive value is the
+ number of MSI vector granted.
+vendor_id :returns programmed vendor id (hex)
+device_id :returns programmed device id(hex)
+bar0_size: :returns size of bar0 in hex.
+bar0_address :returns address of bar0 mapped area in hex.
+bar0_rw_offset :returns offset of bar0 for which bar0_data will return value.
+bar0_data :returns data at bar0_rw_offset.
+
+write behavior of nodes:
+------------------------------
+link :write UP to enable ltsmm DOWN to disable
+int_type :write interrupt type to be configured and (int_type could be
+ INTA, MSI or NO_INT).select MSI only when you have programmed
+ no_of_msi node.
+no_of_msi :number of MSI vector needed.
+inta :write 1 to assert INTA and 0 to de-assert.
+send_msi :write MSI vector to be sent.
+vendor_id :write vendor id(hex) to be programmed.
+device_id :write device id(hex) to be programmed.
+bar0_size :write size of bar0 in hex. default bar0 size is 1000 (hex)
+ bytes.
+bar0_address :write address of bar0 mapped area in hex. (default mapping of
+ bar0 is SYSRAM1(E0800000).Always program bar size before bar
+ address. kernel might modify bar size and address to align. So
+ read back bar size and address after writing to cross check.
+bar0_rw_offset :write offset of bar0 for which bar0_data will write value.
+bar0_data :write data to be written at bar0_rw_offset.
+
+Node programming example
+===========================
+Program all PCIE registers in such a way that when this device is connected
+to the pcie host, then host sees this device as 1MB RAM.
+#mount -t configfs none /Config
+# cd /config/pcie_gadget/
+Now you have all the nodes in this directory.
+program vendor id as 0x104a
+# echo 104A >> vendor_id
+
+program device id as 0xCD80
+# echo CD80 >> device_id
+
+program BAR0 size as 1MB
+# echo 100000 >> bar0_size
+
+check for programmed bar0 size
+# cat bar0_size
+
+Program BAR0 Address as DDR (0x2100000).this is the physical address of
+memory, which is to be made visible to pcie host. Similarly any other peripheral
+can also be made visible to pcie host. e.g if you program base address of UART
+as BAR0 address then when this device will be connected to a host, it will be
+visible as UART.
+# echo 2100000 >> bar0_address
+
+program interrupt type : INTA
+# echo INTA >> int_type
+
+go for link up now.
+# echo UP >> link
+
+It will have to be insured that, once link up is done on gadget, then only host
+is initialized and start to search pcie devices on its port.
+
+/*wait till link is up*/
+# cat link
+wait till it returns UP.
+
+To assert INTA
+# echo 1 >> inta
+
+To de-assert INTA
+# echo 0 >> inta
+
+if MSI is to be used as interrupt, program no of msi vector needed (say4)
+# echo 4 >> no_of_msi
+
+select MSI as interrupt type
+# echo MSI >> int_type
+
+go for link up now
+# echo UP >> link
+
+wait till link is up
+# cat link
+An application can repetitively read this node till link is found UP. It can
+sleep between two read.
+
+wait till msi is enabled
+# cat no_of_msi
+Should return 4 (number of requested MSI vector)
+
+to send msi vector 2
+# echo 2 >> send_msi
+#cd -

Depends on the underlying flow handler. fasteoi does not mask, but I
can see your point. If you have that oddball SA11xx thing, you are
forced to do that, but that is tied into SA11xx and confined.
But if you start to bolt that across platforms with various underlying
chips it simply does not work at all.
For sane primary irq chip implementations it should not matter at all
whether you do it with a chained handler directly or from a regular
requested interrupt.

When calling suspend from cpuidle, do you flush the stack (ie CPU
context) from L2 using outer_cache functions ? This has to be done when
one CPU is shut down with L2 enabled for the MMU off resume path to work
properly.
I think that on resume you invalidate L1 in the reset vector before
jumping to cpu_resume, correct ?

You need at least 100 requests before it'll consider clocking back up.
Once it has 100 requests, no more than 5% of them at the current clock
rate must have failed for it to consider clocking up. I found with
fewer requests, it was forever clocking down, up, down very frequently.

Add more hwmod structures but keep them commented out for the moment
until the driver adaptation to hwmod / omap_device is done.

* [PATCH 6/8] OMAP4: hwmod data: Add DMIC
From: Benoit Cousson @ 2011-02-17 10:24 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1297938289-8678-1-git-send-email-b-cousson@ti.com>
Add HWMOD entries for the OMAP DMIC. The HWMOD entires define the system
resource requirements for the driver such as DMA addresses, channels,
and IRQ's. Placing this information in the HWMOD database allows for
more generic drivers to be written and having the specific implementation
details defined in HWMOD.
