    And enables performance events on the Armadillo board. Perhaps the 
defconfig part was worth a separate patch...

    I think you should either align '=' with tabs, or not bother doing this, 
not both. :-)

As I understand things, the Armadillo is currently the only
board in-tree that uses the r8a7740 SoC and it seems
reasonable to enable performance events to activate the
code that comprises the rest of the patch.

So while I don't feel strongly about this I do have a slight preference
for the current single-patch approach.

Thanks, there seems to be an extra tab there.

I'll roll this into an updated patch and series once
we come to a consensus about the defconfig change.

Not sure what is the status of mach-shmobile with regard to the device
tree, but one of the idea of the device tree is to avoid having one .c
file per board, and therefore one DT_MACHINE_START definition per
board. There should be only only DT_MACHINE_START definition per SoC or
SoC family, with the DT giving the detailed hardware description.

Of course, during a transition period, not all your drivers may have DT
bindings, and therefore some devices may need to be probed in the "old"
way (manual registration of platform_device). In that case, your
->init_machine() hook can call initialization function on a per-board
basis by testing if the machine is such or such board.

See arch/arm/mach-kirkwood/board-dt.c for an example. The advantage is
that with this solution, the board specific C files are progressively
reducing in size as more and more devices get registered through the
Device Tree, until the point where they become empty and can be removed.

Best regards,

Thomas

Hi Thomas,

shmobile is very much in the transition phase and we are, patch by patch,
working towards full(er) DT support for boards, SoCs and drivers. I am not
sure that now is the right time to jump to a approach similar to that taken
by mach-kirkwood/board-dt.c.

Ok, I understand that for transition needs, each SoC family may need a
different method. My comment was more a general comment to make sure
that the right final direction is being taken. For sure the
intermediate steps may be different.

Best regards,

[GIT PULL v2] Renesas ARM-based SoC boards for v3.8 #2

[Simon Horman]

Hi Olof, Hi Arnd,

please consider the following board enhancements for 3.8.

* This pull-request is based on an earlier request which I
  posted on the 1st and was merged yesterday: [GIT PULL v3] Renesas
  ARM-based SoC boards for v3.8

* This pull request replaces the one that I sent yesterday:
  [GIT PULL] Renesas ARM-based SoC boards for v3.8 #2

* Patch #2 of this series has a build-time dependency on
  the soc pull request that I sent a few minutes ago:
  [GIT PULL] Renesas ARM-based SoC for v3.8 #2

  In particular, "ARM: shmobile: marzen: add USB EHCI driver support"
  depends on "[PATCH 1/7] ARM: shmobile: r8a7779: PFC rename PENCx -> USB_PENCx"

* Patch 4 of this pull-request is a driver patch which is a dependency
  of patches 6 and 7 of this pull-request. I have spoken to the driver
  maintainer, Paul Mundt, and he has indicated that he thinks it
  is best to merge all in one go.

  In more detail:

  "sh: clkfwk: add sh_clk_fsidiv_register()" is a dependency of
  - "ARM: shmobile: sh7372: use sh_clk_fsidiv_register() for FSI-DIV clocks"
  - "ARM: shmobile: r8a7740: add FSI-DVI clocks"

----------------------------------------------------------------

[PATCH 5/7] ARM: shmobile: sh7372: sh7372_fsidivX_clk become non-global

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Not only sh7372 but also many Renesas chip has FSI-DIV clock,
and we can share its sh_clk_ops.
To support common FSI-DIV clock, sh7372_fsidivX_clk
becomes non-global by this patch.

[GIT PULL v2] Renesas ARM-based SoC boards for v3.8 #3

[Simon Horman]

Hi Olof, Hi Arnd,

Please consider the following board fix for 3.8.

The commit message for the patch has been revised since yesterday's
pull-request.

Also, please let me know if you would prefer me to supply
this as a fixes branch as we are now in the 3.7-rc6 timeframe
where I understand that non-fix commits are no longer allowed for 3.8.

This commit is based on the renesas/boards2 branch of the arm-soc tree.

[PATCH] ARM: shmobile: mackerel: Add FLCTL IRQ resource

[Simon Horman]

From: Bastian Hecht <hechtb@gmail.com>

Since commit 3c7ea4e (mtd: sh_flctl: Add support for error IRQ)
the sh_flctl driver requires the error IRQ line to signal failed
transactions between the flash controller and the NAND chip.
This information is mandatory - else the driver refuses to start
up. We provide it here for the board mackerel.

It's not super-strictly "fixes only" at this point in the tree, but we really
want to make sure that we don't get any large pull requests from here on out.

For an update like this (adding one more patch on top of a previous branch),
this format is perfect since it allows us to just pull the same branch again,
really. So I've pulled this on top of the previous contents into next/boards2.

[PATCH 02/13] ARM: shmobile: switch SDHI0 to GPIO regulator on armadillo800eva

[Simon Horman]

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

When regulators are used with MMC devices, explicitly provided OCR masks
are ignored, they can be removed from platform data. Also switch SDHI0
from fixed regulator with hard-wired GPIO levels to a proper GPIO regulator
instance to enable dynamic voltage switching.

[PATCH 03/13] ARM: shmobile: streamline mackerel SD and MMC devices

[Simon Horman]

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

This patch fixes the following issues with SD and MMC interfaces on mackerel:
1. replace custom card-detection functions with standard GPIO CD API
2. resources don't have to be numbered
3. add SDHI interrupt names
4. remove OCR masks, where regulators are used
5. only specify SDHI CD interrupts on interfaces where a CD pin is present -
   SDHI0
6. don't instantiate an MMCIF device and initialise MMCIF pins if SDHI1 is
   selected

[PATCH 04/13] ARM: shmobile: mark mackerel sh_mmcif_device __maybe_unused

[Simon Horman]

From: Arnd Bergmann <arnd@arndb.de>

Patch eac036ef9e "ARM: shmobile: streamline mackerel SD and MMC devices"
made the use of the sh_mmcif_device variable for mackarel optional,
but the definition is always provided, causing a build warning.

arch/arm/mach-shmobile/board-mackerel.c:1120:31: warning: 'sh_mmcif_device'
	defined but not used [-Wunused-variable]

Marking the variable as __maybe_unused will do the right thing here.

[PATCH 06/13] ARM: shmobile: kzm9g: Reference DT implementation

[Simon Horman]

Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.

Some notes:

* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
  - MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
  thus external devices may not be used. In particular,
  the SMSC ethernet device may not be used and thus
  NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
  which are needed for a working board:
  - SCIF (Serial)
  - CMT (Clock)
  - PFC (GPIO)

To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.

Includes fix by Thierry Reding to no longer use gic_handle_irq()

Includes fixes by Guennadi Liakhovetski for recent pinmux changes.

[PATCH 07/13] ARM: shmobile: parse DT and configure pinmux early on kzm9g-reference

[Simon Horman]

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

GPIOs can be provided by the pinctrl subsystem, which can be initialised
by DT. Therefore DT has to be parsed before requesting GPIOs. Also non-DT
pinmux has to be configured early.

[PATCH 08/13] ARM: shmobile: SDHI and MMCIF interfaces to kzm9g-reference

[Simon Horman]

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

Add SDHI0 and SDHI2 interfaces to kzm9g-reference. With no pinctrl DT
support we cannot use GPIO card-detection and regulator switching.
Also update the MMCIF DT node to use all 8 data lines and avoid
redundant information in DT.

[PATCH 09/13] ARM: shmobile: simplify kzm9g Kconfig dependencies

[Simon Horman]

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

Reference kernel configurations for armadillo800eva and kzm9g boards do not
have to depend on their respective "legacy" configurations, doing device
instantiation in .c, they can be configured and built independently.

Thanks. I now have no outstanding pull requests.

I do have a few new patches in my tree.
I plan to let a few more accumulate before sending the next pull request(s).

Ok, sounds good.

One general question about your plans (probably more for Magnus than for you):
What is your expected time line for moving shmobile under
CONFIG_ARCH_MULTIPLATFORM? It seems you are making great progress, but
there is also still a lot to be done.

I expect that in 3.10, we will have all ARMv6 and ARMv7 platforms converted,
with the exception of realview, mmp, s5p, msm, and shmobile. I'm sure we
can do realview and mmp for 3.11, possibly also s5p. For shmobile, I think
most of the work would be changing drivers/sh/clk to integrate into the common
clk framework, and you need to find a way to enable ARM_PATCH_PHYS_VIRT and
AUTO_ZRELADDR. Are those things you think can be done for 3.11?

Good to hear that most ARM platforms will be converted by v3.10. This
is definitely something that I want to make happen for mach-shmobile
as well.

Our biggest challenge now is the move to common clocks. I suspect that
moving all our boards and SoCs to common clocks will take much longer
than v3.11 I'm afraid.

Starting with something smaller like EMEV2 may be a good first step.
So somehow I'd like to start converting them one by one, perhaps also
moving over the converted SoCs/boards to CONFIG_ARCH_MULTIPLATFORM in
an incremental fashion. Do you happen to have any example subarch that
has been migrated in an increment fashion already?

Regarding ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR, I believe those
should be enabled for the mach-shmobile bits that are used with
CONFIG_ARCH_MULTIPLATFORM. Best way forward there is TBD, any
recommendations would be very welcome!

Thanks,

Ok, I see. If you think it's not likely to be ready for 3.12, we might
need to discuss again whether there is another way of making the
common clk and the sh-clk code coexist. For instance, we could rename
all if the sh/shmobile specific clk functions and their users from
clk_* to shclk_*, and provide a thin wrapper around them that integrates
into common clk.

We have had a few that were able to do both multiplatform and
single-platform for some time, but then changed to multiplatform-only.
I think mvebu and vt8500 are in this category.

Yes, makes sense.

What I think you should do is rename CONFIG_ARCH_SHMOBILE to
CONFIG_ARCH_SHMOBILE_SINGLE, and add a new symbol in
arch/arm/mach-shmobile/Kconfig like

config ARCH_SHMOBILE
	bool "Renesas SH-Mobile / R-Mobile" if ARCH_MULTI_V6_V7
	default CONFIG_ARCH_SHMOBILE_SINGLE
        help
          Support for Renesas's SH-Mobile and R-Mobile ARM platforms.

This way, the platform is a non-exclusive option for the multiplatform
case, and a hidden enabled option when building CONFIG_ARCH_SHMOBILE_SINGLE.
Every machine that is not ready for multiplatform can then add "depends on
CONFIG_ARCH_SHMOBILE_SINGLE".

Yeah, I am not sure if it is likely that we will be able to convert
all platforms at v3.12 timing.

I actually tried to let common clocks and sh-clk coexist when the
common clock framework was under heavy development. I recall it being
far from trivial.

One possible way to develop this could be to force the mach-shmobile
"reference DT" implementations use common clocks and keep the old
boards as-is. Then we can also make sure the "reference DT"
implementations can be used as CONFIG_ARCH_MULTIPLATFORM. So if we
only have "reference DT" code as MULTIPLATFORM and then finally kill
off the old board code one by one.

I see, that makes sense. Thanks.

Since we're on the topic of CONFIG_ARCH_MULTIPLATFORM, do you have any
recommendatoin about LPAE?

Judging by the ARM_LPAE help text it seems that selecting ARM_LPAE
will result in a kernel only working on LPAE hardware:

config ARM_LPAE
[snip]
          Say Y if you have an ARMv7 processor supporting the LPAE page
          table format and you would like to access memory beyond the
          4GB limit. The resulting kernel image will not run on
          processors without the LPA extension.

With the above text it sounds to me like we should not to a "select
ARM_LPAE" on each board in the case of CONFIG_ARCH_MULTIPLATFORM.

I sort of expect LPAE to behave similar to x86 PAE. At least the board
DT file should describe all physical memory available and depending on
kernel configuration (HIGHMEM=y/n, LPAE=y/n) we get different amounts
of usable memory in the kernel. Then if LPAE should be selected or not
is something that the distributions have to decide.

Thanks!

Works for me, but wouldn't that mean that half the shmobile boards
become incompatible with the other half, forcing you to build two
separate kernels if you want to run on all the machines?

Maybe that's not a problem for you, since you tend to have per-soc
defconfigs  anyway, and it will only be temporary.

Yes. I believe all distros are planning to build one non-LPAE nd one
LPAE kernel. There will have to be a way to enable all LPAE-capable
platforms in Kconfig, but I don't know if that exists already.

Presumably, the LPAE kernel will also be using THUMB2 in the kernel,
while the non-LPAE kernel may get built with ARMv6 platform support
enabled, which rules out THUMB2.

Also, we could enable KVM support in the non-LPAE kernel, but since 
all KVM capable CPU cores (Cortex-A7 and Cortex-A15) so far also
come with LPAE, that's not even necessary.

You can always use #address-cells=<2> in the DT root node if that
helps, and you can also keep your peripherals using #address-cells=<1>
with an appropriate ranges property in the soc bus node.
