[PATCH v6 00/17] ARM: shmobile: r8a7779, marzen: CCF and multiplatform

[PATCH v6 00/17] ARM: shmobile: r8a7779, marzen: CCF and multiplatform

[Simon Horman]

The aim of this series is to add common clock framework and in turn
multiplatform support to the r8a7779 SoC and marzen-reference.  It
subsequently removes non-multiplatform support from marzen-reference.

This is based on work for R-Car Gen2 by Laurent Pinchart and Magnus Damm.


This series is a minor update to v5 to take into account:
* An Ack
* Request for caching of the pin mode
* Patches that have been queued up for v3.16

I intend to merge this series unless there are objections.


Applied on top of a merge of:
* The renesas-devel-v3.15-rc1-20140515 tag of my renesas tree.
* The clk-next branch of Mike Turquettes's tree
  This is to provide the following which were previously part of this series:
  - clk: shmobile: r8a7779: Add MSTP clock support
  - clk: shmobile: r8a7779: Add clocks support


Caveats:

* SMSC_PHY is known not to work with marzen though the reason for
  this is not known. As this is selected in the shmobile_defconfig
  it should be manually disabled before compiling that configuration
  for use on Marzen.

[PATCH v6 03/17] ARM: shmobile: Sync Marzen DTS with Marzen reference DTS

[Simon Horman]

Copy the device nodes from Marzen reference into the Marzen device tree
file. This will allow us to use a single DTS file regardless of kernel
configuration. In case of legacy C board code the device nodes may or
may not be used, but in the multiplatform case all the DT device nodes
will be used.

Based on a similar change for the Lager board by Laurent Pinchart.

[PATCH v6 07/17] ARM: shmobile: r8a7779: Move r8a7779_earlytimer_init to clock-r8a7779.c

[Simon Horman]

r8a7779_earlytimer_init() calls r8a7779_clock_init() and
r8a7779_clock_init() is defined in clock-r8a7779.c.

If both CONFIG_COMMON_CLK and CONFIG_ARCH_R8A7779 are enabled,
as will be the case when marzen-reference moves to use
the common clock framework, then setup-r8a7779.c is compiled
but clock-r8a7779.c is not.

As r8a7779_earlytimer_init() is not used by marzen-reference
simply move it to clock-r8a7779.c.

[PATCH v6 08/17] ARM: shmobile: marzen-reference: Move clock and OF device initialisation into board code

[Simon Horman]

Move the clock initialisation and OF device population from
SoC to board code. This is in keeping with the pattern used by Lager.
And the clock portion is part of decoupling clock initialisation
from SoC code in preparation for moving to the common clock framework.

[PATCH v6 10/17] ARM: shmobile: r8a7779: Initial multiplatform support

[Simon Horman]

Add Marzen and r8a7779 to CONFIG_SHMOBILE_MULTI. At this
point CCF is not yet supported so you cannot run this code
yet. For CCF support to happen several different components
are needed, and this is one simple portion that moves us
forward. Other patches need to build on top of this one.

Marzen board support exists in 3 flavours:
1) SHMOBILE_MULTI, MACH_MARZEN - board-marzen-reference.c (CCF + DT)
2) SHMOBILE, MACH_MARZEN_REFERENCE - board-marzen-reference.c (DT)
3) SHMOBILE, MACH_MARZEN - board-marzen.c (legacy C code)

When CCF is done then 2) will be removed. When 1) includes same features
as 3) then 3) will be removed.

Based on work for the Koelsch and r8a7791 by Magnus Damm.

[PATCH v6 12/17] ARM: shmobile: marzen-reference: Instantiate clkdevs for SCIF and TMU

[Simon Horman]

Now that the common clock framework is supported, the clock lookup
entries in clock-r8a7779.c are not registered anymore. Devices must
instead reference their clocks in the device tree. However, SCIF and CMT
devices are still instantiated through platform code, and thus need a
clock lookup entry.

Retrieve the SCIF and CMT clock entries by name and register clkdevs for
the corresponding devices. This will be removed when the SCIF and CMT
devices will be instantiated from the device tree.

Based on work for the Koelsch board by Laurent Pinchart.

v6
* Update for "ARM: shmobile: r8a7778: Switch to new style TMU device"

v5
* No change

v4
* As suggested by Geert Uytterhoeven and Magnus Damm
  - Make use of shmobile_clk_workaround()
  - This patch now depends on
    "ARM: shmobile: Introduce shmobile_clk_workaround()"

v3
* Initialise TMU clocks instead of CMT clocks
  - It is TMU that Marzen uses as a clocksource
* Refactor clock initialisation hack as per more recent mainline
  code for Koelsch
* Use IS_ERR to check the return value of clk_get()

[PATCH v6 14/17] ARM: shmobile: Remove non-multiplatform Marzen reference support

[Simon Horman]

Now that r8a7779 has CCF support remove the legacy Marzen reference
Kconfig bits CONFIG_MACH_MARZEN_REFERENCE for the non-multiplatform
case.

Starting from this commit Marzen board support is always enabled via
CONFIG_MACH_MARZEN, and CONFIG_ARCH_MULTIPLATFORM is used to select
between board-marzen.c and board-marzen-reference.c

The file board-marzen-reference.c can no longer be used together with
the legacy sh-clk clock framework, instead CCF is used.

I think you also need:
    CONFIG_SPI_SH_HSPI=y
    CONFIG_USB_RCAR_PHY=y
    CONFIG_PM_RUNTIME=y

(the last one is set in all shmobile defconfigs, except ape6evm and shmobile).

The other differences seem to be cruft not really related to hardware support.

Gr{oetje,eeting}s,

After some more consideration I have decided on a slightly modified plan.

1. SPI_SH_HSPI and USB_RCAR_PHY

   Thanks for noticing these. I think they do belong in this patch.
   I plan to queue up the version below:

2. PM_RUNTIME

   I would like to handle this as a follow-up patch.
   In particular, I seem to recall that Magnus wanted to
   hold back on this at some point. So I'd like his input.

While I don't dispute the need for CONFIG_USB_RCAR_GEN2_PHY in
shmobile_defconfig, this is not needed for Marzen, right?

The CONFIG_USB_RCAR_GEN2_PHY was moved from above (by savedefconfig).
I decided to include that change due to proximity to the new
CONFIG_USB_RCAR_PHY line. But perhaps it would have been better not to.

Sorry, I had missed that.

Nevermind.

BTW, avoiding this moving around in real changes is another reason for
refreshing the defconfigs on a regular basis ;-)

Good point.
