[PATCH v7 0/7] Initial Device Tree support for S3C64xx

[Tomasz Figa]

This series adds Device Tree support for Samsung S3C64xx SoC series.

It fixes several problems preventing from booting an S3C64xx-based system
using Device Tree, adds all the infrastructure for Device Tree-based board
support, including mach-s3c64xx-dt and dts include files for S3C64xx SoCs,
and basic device tree source for FriendlyARM Mini6410 and SAMSUNG SMDK6410
boards.

Current support is somewhat limite, but should be fine as a start and
will be extended in future, hopefully with help of S3C64xx board
maintainers.

Depends on:
 - [PATCH v2 0/8] Common Clock Framework support for Samsung S3C64xx
   http://thread.gmane.org/gmane.linux.usb.general/90493

On Samsung S3C6410-based Mini6410 and SMDK6410 boards:

Tested-by: Tomasz Figa <tomasz.figa@gmail.com>

Changes since v6:
 - Rebased onto current for-next branch of Kgene's tree,
 - Dropped the idea of .init_platform() machine callback,
 - Added support for i2c controllers,
 - Replaced separate apb and ahb nodes with a single common soc node,
 - Updated cpus node according to CPU bindings,
 - Updated fixed rate clock nodes to use generic bindings,
 - Added support for PWM buzzer and I2C EEPROM on Mini6410 board,
 - Simplified the condition of skipping legacy GPIO initialization.

Changes since v5:
 - Rebased onto current for-next branch of Kgene's tree,
 - Added support for new Common Clock Framework based clock driver,
 - Introduced hierarchical structure of device nodes (representing
   physical AHB and APB buses),
 - Bypassed most of legacy initialization when booting with DT,
 - Used preprocessor macros in dts files to improve readabilty,
 - Added support for SMDK6410 board.

Changes since v4:
 - Rebased onto current for-next branch of Kgene's tree
 - Added support for pinctrl (driver merged through pinctrl tree)
 - Added labels to all nodes that can be overridden from board dts
 - Modified board dts to use the &label syntax to reference device nodes

Changes since v3:
 - Rebased onto current for-next branch of Kgene's tree
 - Updated timer node for next version of samsung-time patches
 - Replaced local s3c64xx_dt_init_irq with irqchip_init

Changes since v2:
 - Updated timer node for next version of samsung-time patches

Changes since v1:
 - Dropped two VIC-related patches that are no longer necessary
 - Added Device Tree-based instantation of system timers
 - Corrected VIC interrupt specifiers
 - Adjusted CPU compatible values and dropped @id

The "interrupt-mask" is called "valid-mask" on the FPGA IRQ controller
See
Documentation/devicetree/bindings/arm/versatile-fpga-irq.txt

Example:

                reg = <0x10000040 0x100>;
                clear-mask = <0xffffffff>;
                valid-mask = <0x00000007>;

Please use the same name.

(wakeup-mask is fine).

This patch extends vic_of_init to parse valid interrupt sources
and resume sources masks from device tree.

If mask values are not specified in device tree, all sources
are assumed to be valid, as before this patch.

Can you explain further why the VIC needs this information up-front?
Presumably it can accumulate it as devices request interrupts.

Until a device requests an interrupt, it can be left disabled. Once
something does request it, it gets enabled. If nothing requests it, it
never gets enabled. Doesn't the result of that logic end up being the
same thing as valid-mask represents? The only difference would be if
some device requests an invalid interrupt source, but then why not just
fix the interrupt client instead of adding this property to reject the
request?

Shouldn't drivers for end-devices request interrupts, and then set wake
enable on those interrupts, which would then trickle up the IRQ chain to
tell the VIC which interrupts to enable wakeup on?

It does not need this information just for operation, but this makes the 
hardware description more detailed and allows better sanity checking of 
interrupts being requested.

To clarify, this is a mask of valid interrupt sources of the VIC, where 
set bit indicates that given signal is wired and clear bit that it is not.

This property does not have anything to do with enabling or disabling (aka 
unmasking/masking) of interrupts. It just lists valid interrupt signals of 
given VIC.

This is the same as previous property. It does not have anything to do 
with requesting particular signal to wake up the system, but rather 
indicating that particular signal _can_ be requested to do so.

Again, this is not strictly needed for correct operation, but this way you 
wouldn't get any sanity check over wake up signals being requested.

Ah, OK. It may be worth mentioning the intent of the properties. I
suppose this is purely a representation of HW then, so it's reasonable
to include it in the binding. I'm not sure /quite/ how useful it is;
after all the error-checking that it enables will never trigger assuming
the rest of the DT is written to "request" the correct interrupts.
However, I guess there is little harm in allowing these properties.

Bikeshedding a bit, but perhaps rename wakeup-mask to valid-wakeup-mask
(and perhaps valid-mask to valid-source-mask for consistency, although I
see you already renamed that to be consistent with other bindings...)?
To me, wakeup-mask sounds like a configuration of which sources should
be configured to wakeup the system; something to do with
configuration/policy rather than HW capabilities.

Either way, the binding,
Acked-by: Stephen Warren <swarren@nvidia.com>

(I assume those 2 new properties always have 1 cell since the controller
can only support up to 32 IRQ sources? If not, then perhaps add wording
to describe how long the properties should be).

Right, a bit more detailed description will be nice indeed. I didn't think 
such thing like this is so uncommon to need such.

Well, the valid-mask is indeed a bit redundant (although might let you 
spot errors in interrupt specification in your device tree faster), but 
wakeup-mask is something that prevents drivers from incorrectly thinking 
that an interrupt can wake the system up, while it can't. Otherwise 
enable_irq_wake() wouldn't know when to return an error.

Yes, valid-wakeup-mask sounds reasonably to me. The valid-mask property 
has been taken from bindings/arm/versatile-fpga-irq.txt, as suggested by 
Linus Walleij.

Correct, one VIC can support up to 32 interrupt sources. A word on this in 
binding description will be nice indeed.

I agree with Stephen here. The valid interrupts are the ones in the
DT. The reserved ones are the ones not present. If it is not needed
for the operation of the VIC, then remove it. The argument of sanity
checking could apply to all interrupt controllers.

Sorry, but I don't get what's wrong in having a more detailed description 
than required just for operation of the hardware.

The feature of sanity checks based on interrupt_mask (here now called 
valid-mask) has been present in the VIC driver since a long time already 
(if not from the beginning of existence of this driver) and before we 
started using DT, the mask was being passed from platform code as VIC init 
function argument.

I'd prefer this feature to be available when using DT as well, unless we 
really want to move things backwards, just because we want to use DT...

Tomasz

As I mentioned all these arguments apply to ALL interrupt controllers
except ones which a mask does not work. So IF this makes sense, then
this should be a generic property and generic code to support.

You simply have the same information twice. One is distributed and one
is centralized. While it adds a way to validate things it also adds a
way to introduce errors. Suppose someone writes a dts such that
valid-mask matches the irq lines present in that dts (simply because
they were lazy or don't have documentation of all interrupt lines). Then
you go add a node with a new interrupt (because the initial dts was not
complete). Updating the valid-mask could very easily be forgotten. Yes,
this should all be found by testing, but people don't always have access
to all the h/w. This issue would also not likely be obvious in a review.

I would put it different way: The binding should provide information 
detailed enough to allow any features allowed by Linux software design.

Well, anyway, I don't believe that existing, pre-ARM, bindings wasn't 
influenced by how things worked on PowerPC platforms and software running 
on them (including OpenFirmware and OS'es like Linux).

Isn't a binding of particular device free to define a private property? 
Anyway, I wouldn't be opposed to making it generic.

That's why this property is optional. If you don't know how this is set up 
on your hardware then you don't fill it with a random value, but just skip 
it instead.

Adding a node with a new interrupt usually means adding support for new 
hardware. This is something I wouldn't really want to see submitted 
untested...

Anyway, since I'd like this series to be merged ASAP and this patch is not 
strictly necessary, especially this optional sanity check, let me just 
drop this property and move on with other things...

[PATCH v7 2/7] ARM: s3c64xx: Bypass legacy initialization when booting with DT

[Tomasz Figa]

This patch allows bypassing most of legacy initialization when booting
an S3C64xx-based board using device tree, by adding conditional checks
for DT presence to initcalls which are no longer necessary when booting
with DT..

[PATCH v7 2/7] ARM: s3c64xx: Bypass legacy initialization when booting with DT

[Tomasz Figa]

This patch allows bypassing most of legacy initialization when booting
an S3C64xx-based board using device tree, by adding conditional checks
for DT presence to initcalls which are no longer necessary when booting
with DT..

[PATCH v7 3/7] gpio: samsung: Skip initialization if device tree is present

Since this driver does not handle GPIO on device tree enabled platforms
any more, it should be bypassed whenever device tree is available, to
not conflict with the new pinctrl-samsung driver.

This seems like something I should apply to the GPIO tree

Would be nice, but since this patch is a dependency for rest of this 
series and there are no other dependencies on GPIO tree, it might be 
easier to just let Kukjin take all the patches with required Acks.

Though if the rest of the series might miss v3.12 (seems likely given
the arm-soc deadlines have passed) then Linus could apply this for
v3.12?

Oh, I didn't see any dependencies...but if so, Linus do you agree with
Tomasz' opinion?

Please let me know so that I could take this with others into the samsung

Without this patch DT-based bootup would fail, because the legacy GPIO 
driver would kick in and register GPIO chips before the pinctrl driver. 
Things would compile fine, though. So this is a run time dependency, not 
compile time.

I would be really happy if we could finally merge this for this release. 
This series is not really invasive in any way, so it is unlikely to 
introduce any regressions and it has waited so many releases, without any 
significant changes, due to a lot of other dependencies.

Tomasz

[PATCH v7 5/7] ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs

[Tomasz Figa]

This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.

[PATCH v7 5/7] ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs

[Tomasz Figa]

This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.

[PATCH v8 5/7] ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs

[Tomasz Figa]

This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.

[PATCH v8 5/7] ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs

[Tomasz Figa]

This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.

[PATCH v9 5/7] ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs

[Tomasz Figa]

This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.

[PATCH v9 5/7] ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs

[Tomasz Figa]

This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.
