In preparation for adding device tree overlay support, OF_DYNAMIC is reworked so that a set of device tree changes can be prepared and applied to the tree all at once. OF_RECONFIG notifiers see the most significant change here so that users always get a consistent view of the tree. Notifiers generation is moved from before a change to after it, and notifiers for a group of changes are emitted after the entire block of changes have been applied Automatic console selection from DT. Console drivers can now use of_console_check() to see if the device node is specified as a console device. If so then it gets added as a preferred console. UART devices get this support automatically when uart_add_one_port() is called. DT unit tests no longer depend on pre-loaded data in the device tree. Data is loaded dynamically at the start of unit tests, and then unloaded again when the tests have completed. Also contains a few bugfixes for reserved regions and early memory setup" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: (21 commits) of: Fixing OF Selftest build error drivers: of: add automated assignment of reserved regions to client devices of: Use proper types for checking memory overflow of: typo fix in __of_prop_dup() Adding selftest testdata dynamically into live tree of: Add todo tasklist for Devicetree of: Transactional DT support. of: Reorder device tree changes and notifiers of: Move dynamic node fixups out of powerpc and into common code of: Make sure attached nodes don't carry along extra children of: Make devicetree sysfs update functions consistent. of: Create unlocked versions of node and property add/remove functions OF: Utility helper functions for dynamic nodes of: Move CONFIG_OF_DYNAMIC code into a separate file of: rename of_aliases_mutex to just of_mutex of/platform: Fix of_platform_device_destroy iteration of devices of: Migrate of_find_node_by_name() users to for_each_node_by_name() tty: Update hypervisor tty drivers to use core stdout parsing code. arm/versatile: Add the uart as the stdout device. of: Enable console on serial ports specified by /chosen/stdout-path ...

| | | | | | | | | | | | | | | | Add a stdout-path property to the Versatile devicetree so that automatic console selection works without needing a console= line on the kernel command line. Signed-off-by: Grant Likely <grant.likely@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | The versatile dts is missing any clock data. Add the clocks. It is not clear from the documentation where pclk comes from, so for now it is a dummy clock which is sufficient for things to work.

| | | | | | | | | Two of the versatile irq definitions are incorrect, mostly because two devices have connections to more than one interrupt controller. Fix them by using the new interrupts-extended property to fan out without using an awful interrupt-map nexus node. Signed-off-by: Grant Likely <grant.likely@linaro.org>

* ARM: 7390/1: dts: versatile-pb/ab fix MMC IRQsLinus Walleij2012-04-231-1/+1
| | | | | | | | | | | | The MMCI driver will not work without two IRQs since this is not flagged as a single-irq variant. Looking through the complex IRQ definition for the MMCI on the versatile (including an #if 1 statement forcing MMCI IRQ0 to the VIC) this appears to the the correct IRQ number for both models.

* arm/versatile: Add device tree supportGrant Likely2011-07-281-0/+192
For testing the dt work, define a dt-enabled versatile platform. This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.
