* ARM: ux500: Allow PRCMU regulator to be probed during a DT enabled bootLee Jones2012-06-011-0/+1
| | | | | | | | | | This patch adds the correct compatible string for use during Device Tree population. Without it the DB8500 PRCMU regulators would be processed when DT is enabled.

* ARM: ux500: Only initialise STE's UIBs on boards which support themLee Jones2012-06-013-3/+10
| | | | | | | | | | | | | ST-Ericsson uses User Interface Boards to extend functionality of some of their development boards. However, these aren't compatible with all the supported boards found in Mainline (Snowball for instance). This patch ensures that the UIBs are only probed on boards which can actually support them. This in turn saves lots of unnecessary error messages normally found in Snowball's boot log.

* ARM: ux500: Disable platform setup of the ab8500 when DT is enabledLee Jones2012-06-011-3/+4
| | | | | | | | | | | | The final piece of the ab8500 puzzle. Here we prevent any of the ab8500-* drivers from being registered from platform code when Device Tree is enabled, as we expect DT do probe each of these individually. We also provide the relevant compatible strings, so that DT knows which nodes it needs to pay attention to during population.

* ARM: ux500: Re-enable SMSC911x platform code registration during non-DT bootsLee Jones2012-06-011-0/+1
| | | | | | | | | | | | The patch to disable SMSC911x registration was applied twice in the upstream kernel by mistake. Git interpreted this as 'take the same entry from a similar struct' which was close by. This was the wrong thing to do. This patch rectifies this error and re-enables SMSC911x registration when Device Tree is not enabled.

* ARM: ux500: Remove DB8500 PRCMU platform registration when DT is enabledLee Jones2012-06-011-2/+1
| | | | | | | | | | Now the DB8500 has Device Tree support it will be probed when the DT is parsed, rendering the requirement for platform registration void.

* ARM: ux500: Disable SMSC911x platform code registration when DT is enabledLee Jones2012-06-011-2/+1
| | | | | | | | | | Now the SCMC911x is correctly enabled in Device Tree, there is no need to continue registering it from platform code. In fact, if we continue doing so, the system will throw an error on boot.

| | | | | | | | | | | | During Device Tree enablement it is necessary to remove <hw_component>_add_<device> calls one at at time, as and when particular devices are DT enabled.

| | | | | | | | | | | | | | | | | | | | | | ab8500-i2c is used as core code to register the ab8500 device.

We define GPIO ranges to cover the pins exposed. The DB8500 has more pins than this but we restrict the driver to the pins that can be controlled from the combined GPIO and pin control hardware to begin with. ChangeLog v1->v2: - Base on the latest pinctrl development from pinctrl-mergebase-20120418 so we can get rid of legacy group count mechanism. Also drop the range checks for group index, this is handled by the core now. Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

However on most reference designs the electronics already contain external pull-ups which means the internal pull-ups will lower the common resistance and increase power consumption on these lines, and in some reference designs the keypad inputs are not used so this will just cause problems. So remove these pull-ups and add them on demand instead if needed.

The cpu_is_u5500() macros that can read out the CPU ID is left until the next kernel cycle, this makes it possible to merge deletion of dependent drivers without breakage. This also has the upside of removing the mailbox driver which was our only driver that was outside the drivers/* hiearchy, now the machine directory only handles machines and nothing else.
