GPIO numbers for the newly created gpio-regulator will differ from board to board. Therefore it's not sensible to leave this information in the top level DTSI file. Let's move them out to the DTS files where they can correctly vary. Acked-by:

Not all supported boards will require a MMCI gpio-regulator, therefore it's a good idea to only enable the node when and if it is required. Let's disable it by default. Acked-by:

UARTs no longer require call-back information, since the reset call-back was removed in 43b5f0d6. The only AUXDATA dependencies remaining for UARTs are DMA settings. Acked-by:

Here we add the device node for the SDI4 (MMC) port to the u9540 Device Tree source file. This will allow successful probing of the internal MMC storage device when booting with DT enabled. Acked-by:

Regulator supply names should be allocated by board rather than per SoC, as the same SoC could be wired differently on varying hardware. Here we push all regulator-name allocation out to the dbx5x0 subordinate board files; HREF and Snowball. Requested-by:

The Device Tree machine description for the ux5x0 was moved recently and as a consequence missed the addition of SMP operations. Without this patch SMP doesn't work and only one CPU is present after booting. Acked-by:

It is the intention to convert the MMC voltage changing from GPIO flipping to using a proper GPIO regulator interface. A prerequisite of that is to enable the GPIO regulator functionality. As this affects all ux5x0 based boards we'll do it here instead of in the Kconfigs. Acked-by:

On boot the Nomadik GPIO controller complains that an IRQ can't be configured as active high level-sensitive, so this patch converts it to be low-to-high edge triggered instead. Acked-by:

There is a very simple mechanism to change and SDI's voltage which consists of toggling some GPIOs. This scenario can be better handled if we convert it to a GPIO regulator. This patch provides one which can be read from Device Tree. Acked-by:

So far, each ST-Ericsson board supported by Device Tree has been similar enough to run though a single DT_MACHINE_INIT call. On the back of that it has been suggested that we should reduce the number of compatible strings in our dt_compat structure. After subsequent discussion with Arnd Bergmann the conclusion was to list entries by platform as opposed to by board. The other suggestion was to use a single string which would cover all supported platforms, but any wildcard entries would include unsupported chipsets, such as the u5500 and potential new chips which no not yet have DT functionality. Hence, the best solution which encompasses all supported platforms, but no unsupported ones was to list the currently enabled four chipsets; u8500, u8540, u9500 and u9540 instead. Acked-by:

The u8500 and u9540 DT_MACHINE_START calls are almost identical at the moment, referencing exactly the same function pointers. Until this changes we may as well convert the original one to be more generic and use that instead. Acked-by:

When enabling ST-Ericsson's ccu9540 development board the board's full name has not been used. This patch adapts all references of the board's short name to how it should be referenced. Reviewed-by:

'st-ericsson,u8500' is too much of a broad name to be used for any of the supported development boards supported by ST-Ericsson. As such it was never used. It has no place to remain in the board compatible list, hence why it's being removed. Acked-by:

As there will be a Device Tree created for the UIBs, there is no need to call the UIB initiation functions. Each device will be detailed and registered from the Device Tree instead. Acked-by:

To aid the kernel in its effort to move to DT only booting, we're transplanting all Device Tree related code to cpu-db8500 which will remain persistent throughout the transition. This change paths the way for complete removal of board-mop500, which will be done once the all DMA settings are moved into the respective DT source files. Acked-by:

Most devices have now been successfully DT:ed and each supported platform has its own Device Tree source file. Hence the majority of the platform specific device registration calls can now be successfully removed. Acked-by:

In ux500 platform code we currently support a number of devices. Two of these devices are fairly similar, but have key differences. Early (pre-v60) HREFs and the more up-to-date versions (v60+), and they both need to be supported by Device Tree. Here we apply a DT source file for the earlier versions. Acked-by:

There are two main versions of the ST-Ericsson hardware reference board, each with subtle differences. These versions are described in current platform data as 'mop500' for HREF v1.1 & v2.0 and 'hrefv60+' for latter incarnations. However, the boards have much in common, so this patch creates a .dtsi (Device Tree Source Include) file which describes the similarities between the two boards and individual 'hrefprev60' and 'hrefv60plus' .dts files which depict the differences.

An earlier change prevented User Interface Boards (UIBs) from being initialised on boards which did not support them. This change had the undesired effect of reordering the UIB initialisation calls with I2C registration. Here we ensure UIBs are only setup after all required infrastructure is already in place.
