ARM: mach-shmobile: kzm9g: Reference DT implementation

this is a third pass at at providing a refernce DT implementation for the kzm9g baord which is intended to act as a guide for mach-shmobile developers.

It provides a minimal setup of the board using as little C code as possible.

It may be used by selecting CONFIG_MACH_KZM9G_REFERENCE and using sh73a0-kzm9g-reference.dtb

*** Please note that the clock initialisation shcheme used in
this series does not currently work with SMP as there is a yet to be resolved lock-up in workqueue initialisation.

Resolving this problem is currently regarded as future-work.

CONFIG_SMP must be disabled when using this code. ***

Major difference between v2 and v3:
* Allow UP boot to complete by initialiing CMT earlier. This is achieved by changing the position of clocsources/ in drivers/Makefile

Major difference between v1 and v2:
* Drop touchscreen initialisation, it requires INTC
* Drop SDHI initialisation, the driver seems to need some work
* Add extra entries to clock-sh73a0.c:lookups[] and
remove auxdata. Ultimtely the clocks will be described
in DT, but the code isn't there yet.
* Drop MMCIF patch, it is not needed if regulators are enabled
* Drop PCF hacks, instead, the series is based on Laruent Pinchart's *
* series: [PATCH v2 00/77] SH pin control and GPIO rework with OF support
* Use shmobile_setup_delay()

1.7.10.4

Hi Simon,

Thanks for the patch.

Could you please CC LKML on this one ? It targets a wider audience than the SH-specific patches.

Regards,

Laurent Pinchart

Sure, good thinking.

This allows the GIC interrupt controller of the sh73a0 SoC to be initialised using a flattened device tree blob.

It does not allow the INTC interrupt controller which is also present on the sh73a0 SoC to be enabled via device tree. Nor does it handle sharing of interrupts between the GIC and INTC interrupt controllers.

This limits the usefulness of this code to applications which only wish to access devices which use interrupts that can be handled by the GIC interrupt controller. Other applications should, for now, continue using non-device tree initialisation of the sh72a0 interrupt controllers.

1.7.10.4

Allow a minimal setup of the sh73a0 SoC using a flattened device tree. In particular, Configure the i2c controllers using a flattened device tree.

SCI serial controller and CMT clock source, whose drivers do not yet support configuration using a flattened device tree, are still configured using C code in order to allow booting of a board with this SoC.

*** Please note that the clock initialisation shcheme used in
this patch does not currently work with SMP as there is a yet to be resolved lock-up in workqueue initialisation.

CONFIG_SMP must be disabled when using this code. ***

remove auxdata. Ultimtely the clocks will be described

v3
* No change

v2
* Removed SDHI initialisation as the driver needs updating first
* Moved MMC DT from sh73a0.dtsi to sh73a0-reference.dtsi as it is not appropriate for use by sh73a0-kzm9g.dts yet. This is because sh73a0-kzm9g.dts and board-kzm9g.c use both the GIC and INTC interrupt controllers to provide access to a rich set of devices. This is achieved by initialising the interrupt controllers using C code. Work on allowing the INC controller to be initialised using DT is in progress, however, until that is complete only GIC may be initialised using DT.
* Add extra entries to clock-sh73a0.c:lookups[] and remove auxdata. Ultimately the clocks will be described in DT, but the code isn't there yet.

1.7.10.4

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.

*** Please note that the clock initialisation shcheme used in
this patch does not currently work with SMP as there is a yet to be resolved lock-up in workqueue initialisation.

CONFIG_SMP must be disabled when using this code. ***

---

v3
* Compile board-kzm9g.c even if CONFIG_MACH_KZM9G_REFERENCE is selected, it can co-exist with board-kzm9g-reference.c

v2
* Do not initialise touchscreen, it requires the INTC interrupt controller but for now this configuration only has the GIC interrupt controller.
* Define mmcif and sdhi in SoC dtsi and reference in board dts.
* Do not initialise SDHI, the driver needs to be updated
