[PATCH 7/7] ARM: shmobile: Add SDHI devices for Koelsch DTS

[Simon Horman]

From: Magnus Damm <damm@opensource.se>

Add DT support for SDHI0, SDHI1 and SDHI2 on Koelsch.

The board specific handling of CD and WP pins are
using GPIOs. SDHI0 and SDHI1 are hooked up to regular
SD connectors while SDHI2 is using micro-SD which
is lacking WP signal.

[PATCH] ARM: shmobile: r8a7791: Fix SCIFA3-5 clocks

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>

The MSTP clocks for SCIFA3-5 are MSTP1106-1108, not MSTP1105-1107

Also reinsert them at the correct position to preserve sort order.

[PATCH] ARM: shmobile: r8a7791: Fix SCIFA3-5 clocks

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>

The MSTP clocks for SCIFA3-5 are MSTP1106-1108, not MSTP1105-1107

Also reinsert them at the correct position to preserve sort order.

Hi,

I've merged this into next/dt. However, a general comment on these patches:

> Sergei Shtylyov (4):
>       ARM: shmobile: r8a7790: add Ether DT support
>       ARM: shmobile: lager: add Ether DT support

I think you should consider doing a generic binding for the ethernet
controller, that specifies the data that the driver needs as part of the device
tree contents. that way you don't have to add a new _data structure for every
new SoC that implements things -- from taking a brief look at the driver there
seems to be a bit of boiler plate and/or several parts that share common
feature sets already.

Anyway, given the way the binding is written, this can be done later by adding
a generic compatible string that expects more properties, etc -- so it's not
something that needs to be done now. But I do recommend that as you add new
SoCs in the future (if you do).

Hi Olof,

Thanks for your suggestion. If I understand your proposal correctly
then you recommend us to make the driver more generic and
configuration driven based on configuration from DT. In general I
agree about this direction, but in the case of sh-eth this seems
difficult due to huge differences between different IP variants. And
to make it worse, the documentation is often of poor quality with no
real IP version information. Because of this we keep knowledge in the
driver and adjust behavior using the SoC number as suffix in the
compatible string. The SoC number is the only "stable id" we have that
is suitable for DT ABI unfortunately.

Of course I welcome further data sharing, cleanups and bug fixes for
this driver. If you can think of anything in particular please let me
or one of the sh-eth developers know. I will do my best to help you.

Thanks,

My observation was mostly based on the fact that while there are a
number of tunables in the platform data, there seems to mostly be a
few different main collections of settings used. I.e. several of them
seem to share several of the tunables.

Maybe that's mostly coincidental, or maybe it's an indication that
most "similar-timeframe" SoCs used similar settings -- I don't know
enough to tell. Which is why I brought it up.

My observation was mostly based on the fact that while there are a
number of tunables in the platform data, there seems to mostly be a
few different main collections of settings used. I.e. several of them
seem to share several of the tunables.

Maybe that's mostly coincidental, or maybe it's an indication that
most "similar-timeframe" SoCs used similar settings -- I don't know
enough to tell. Which is why I brought it up.

I understand and agree. So similar SoCs may share the same tunables,
but if this is correct or not for all cases remains to be seen.

Actually, for sh-eth the documentation has been so poor that for some
SoCs we have to rely on undocumented registers. Because of the lacking
docs the question in my mind is where to draw the line for the ABI. By
keeping the compatible string fixed to the SoC suffix we make sure the
DTB remains compatible as long as the driver knows how to handle the
hardware. Then when we get a surprise data sheet update then we don't
have to break the ABI.

> Maybe that's mostly coincidental, or maybe it's an indication that

Historically this driver was initially developed for SH-based SoCs,
and because of that the platform data interface supports a wider range
of devices than DT which is ARM-only. There may be some
"similar-timeframe" cases too. But for sh-eth it is a mix of fast and
gigabit ethernet controllers with RMII or GMII interfaces.

One way to deal with "similar tunables" is to break out similar
versions of the IP into a certain "software defined IP block version",
but wouldn't we describe the current state of the driver then instead
of the actual hardware? Just because the driver may work with two
different IP versions does not mean they are naturally hardware
compatible in my opinion.

To keep things simple I'd like to enforce a "SoC suffix" compatible
string policy for our drivers. I know it does not scale but in my
opinion this is the place for simplicity and stability. In parallel we
need to work on getting the IP version described in the documentation
as expected. Once we have IP version in the documentation then we can
use that in the compatible string and then hopefully we are in a
better place.

[GIT PULL] Fourth Round of Renesas ARM Based SoC Clock Updates for v3.17

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these fourth round of Renesas ARM based SoC clock
updates for v3.17.

I am sending this even though v3.16-rc6 has long since been released
as this pull-request only includes a single one line fix for a problem
introduced in patches you have already queued up for v3.16.

At it turns out the problem should not manifest at run time
as it is an error in an clock that is not used without DT modifications.
As such I am happy for you to ask me to defer this to v3.18 if you like.

This pull request is based on the previous round of
such requests, tagged as renesas-clock3-for-v3.17,
which you have already merged.


The following changes since commit a0f7e7496d56ac2da7c684e2035815318c17973a:

It is less work to just apply a patch when there's a single one like
this. Please just send it and ask us to apply it on top of the
previous branch.

[PATCH 1/3] ARM: shmobile: lager: correct memory map

[Simon Horman]

The base address of the second memory region on the lager
board is 0x140000000. Update the tag used in the dts file accordingly.

This is a documentation fix and should have no run-time affect.

This problem was introduced when the second memory region
was added to the lager dts file by 62bc32a2573c4219
("ARM: shmobile: Include all 4 GiB of memory on Lager)"
in v3.14.

Is this correct, i.e. does "scif2" match "ttySC0" below?

To answer my own question: the alias means that "ttySC0" will be mapped to
the scif2 hardware block, using of_alias_get_id().

Pulled into next/dt, thanks!

There is one new warning I got in the for-next branch after the last round
of pull requests, in mackerel_defconfig:

arch/arm/mach-shmobile/pm-sh7372.c:116:33: warning: 'sh7372_pm_domains' defined but not used [-Wunused-variable]
 static struct rmobile_pm_domain sh7372_pm_domains[] = {
                                 ^

I haven't looked at it in detail, can you find out what caused it and
send a fix with your next round?

That's due to sh7372_init_pm_domains() being protected by #ifdef CONFIG_PM,
while rmobile_init_domains() is a dummy macro if !CONFIG_PM_RMOBILE.

I think the first #ifdef should also test for CONFIG_PM_RMOBILE, to be
consistent.

However, I don't see the warning with my current tree, nor with next-20140910,
as both are selected with mackerel_defconfig, due to:

 config ARCH_RMOBILE
        bool
        select PM_RMOBILE if PM && !ARCH_SHMOBILE_MULTI

Perhaps this change hadn't trickled from Simon's tree into your tree, due
to following a different merge path?

Ah, you are right, I was testing with another branch merged in that changed
some of the Kconfig statements in shmobile to work around randconfig build
problems. Apparently one of the patches in my branch was wrong, the
shmobile branches are all good.

Sorry for the noise.

[PATCH] ARM: shmobile: r8a7794: Remove unnecessary #ifdef CONFIG_USE_OF

[Simon Horman]

The r8a7794 support is always compiled using ARCH_MULTIPLATFORM which
selects USE_OF. So #ifdef CONFIG_USE_OF is unnecessary.

[PATCH] ARM: shmobile: Add early debugging support using SCIF(A)

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add serial port debug macros for the SCIF(A) serial ports.
This includes all supported shmobile SoCs, except for EMEV2.

The configuration logic (both Kconfig and #ifdef) is more complicated than
one would expect, for several reasons:
  1. Not all SoCs have the same serial devices, and they're not always
     at the same addresses.
  2. There are two different types: SCIF and SCIFA. Fortunately they can
     easily be distinguished by physical address.
  3. Not all boards use the same serial port for the console.
     The defaults correspond to the boards that are supported in
     mainline. If you want to use a different serial port, just change
     the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt.
  4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual
     address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END
     = 0xff000000, and must not conflict with the 2 MiB reserved region
     at PCI_IO_VIRT_BASE = 0xfee00000.
       - On SoCs not using the legacy machine_desc.map_io(),
	 debug_ll_io_init() is called by the ARM core code.
       - On SoCs using the legacy machine_desc.map_io(),
	 debug_ll_io_init() must be called explicitly. Calls are added
	 for r8a7740, r8a7779, sh7372, and sh73a0.

This was derived from the r8a7790 version by Laurent Pinchart.

[PATCH] ARM: shmobile: Add early debugging support using SCIF(A)

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add serial port debug macros for the SCIF(A) serial ports.
This includes all supported shmobile SoCs, except for EMEV2.

The configuration logic (both Kconfig and #ifdef) is more complicated than
one would expect, for several reasons:
  1. Not all SoCs have the same serial devices, and they're not always
     at the same addresses.
  2. There are two different types: SCIF and SCIFA. Fortunately they can
     easily be distinguished by physical address.
  3. Not all boards use the same serial port for the console.
     The defaults correspond to the boards that are supported in
     mainline. If you want to use a different serial port, just change
     the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt.
  4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual
     address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END
     = 0xff000000, and must not conflict with the 2 MiB reserved region
     at PCI_IO_VIRT_BASE = 0xfee00000.
       - On SoCs not using the legacy machine_desc.map_io(),
	 debug_ll_io_init() is called by the ARM core code.
       - On SoCs using the legacy machine_desc.map_io(),
	 debug_ll_io_init() must be called explicitly. Calls are added
	 for r8a7740, r8a7779, sh7372, and sh73a0.

This was derived from the r8a7790 version by Laurent Pinchart.

[GIT PULL] Fourth Round of Renesas ARM Based SoC DT Updates for v4.3

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these fourth round of Renesas ARM based SoC DT updates for v4.3.

As requested by Olof, this is a repost of patches broken out of a now
defunct pull-request, "Renesas ARM Based SoC CPG MSTP Clock Domain Updates
for v4.3".  The motivation being to have driver changes in a separate
branch to DT changes.


This pull request is based on a merge of:

* "Renesas ARM Based SoC CPG/MSTP Clock Driver Updates for v4.3",
  tagged as renesas-clk-for-v4.3, which I have also sent a pull request for.

  The patches in this pull request depend on driver changes in
  renesas-clk-for-v4.3.

* "Third Round of Renesas ARM Based SoC DT Updates for v4.3",
  tagged as renesas-dt3-for-v4.3, which you have already merged.

  The patches in this pull request update nodes added by patches
  present in renesas-dt3-for-v4.3.


The following changes since commit 3f3f0ea0afe031ca20e48a212f4faa00f9920450:

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.

[PATCH 2/7] ARM: shmobile: r8a7778 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.  A notable
exception is the "sound" node, which represents multiple SoC devices,
each having their own MSTP clocks.

[PATCH 4/7] ARM: shmobile: r8a7790 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.  Notable
exceptions are the "display" and "sound" nodes, which represent multiple
SoC devices, each having their own MSTP clocks.

[PATCH 4/7] ARM: shmobile: r8a7790 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.  Notable
exceptions are the "display" and "sound" nodes, which represent multiple
SoC devices, each having their own MSTP clocks.

[PATCH 5/7] ARM: shmobile: r8a7791 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.  Notable
exceptions are the "display" and "sound" nodes, which represent multiple
SoC devices, each having their own MSTP clocks.

[PATCH 5/7] ARM: shmobile: r8a7791 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.  Notable
exceptions are the "display" and "sound" nodes, which represent multiple
SoC devices, each having their own MSTP clocks.

[PATCH 6/7] ARM: shmobile: r8a7793 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.

[PATCH 7/7] ARM: shmobile: r8a7794 dtsi: Add CPG/MSTP Clock Domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.
