2012-07-23MIPS: Octeon: Use device tree to register serial ports.David Daney
Switch to using the device tree to register serial ports. Add all the ports with compatible = "cavium,octeon-3860-uart". Octeon serial ports have their own device type, required port flags, and I/O functions, so using of_serial.c is not indicated. We need to do this as late_initcall, as the 8250 driver must be initialized before we add any ports. 8250 initialization is done at device_initcall time. The OCTEON_IRQ_UART{0,1,2} symbols are removed as they are now unused and interfere with irq_domain used by the device tree code.

2012-07-23i2c: Convert i2c-octeon.c to use device tree.David Daney
There are three parts to this: 1) Remove the definitions of OCTEON_IRQ_TWSI and OCTEON_IRQ_TWSI2. The interrupts are specified by the device tree and these hard coded irq numbers block the used of the irq lines by the irq_domain code. 2) Remove platform device setup code from octeon-platform.c, it is now unused. 3) Convert i2c-octeon.c to use device tree. Part of this includes using the devm_* functions instead of the raw counterparts, thus simplifying error handling. No functionality is changed.

2012-07-23MIPS: Octeon: Add device tree source files.David Daney
The two device tree files octeon_3xxx.dts and octeon_68xx.dts are trimmed by code in a subsequent patch to reflect the hardware actually present on the board. To this end several properties that are not part of the declared bindings are added to aid in trimming off unwanted nodes. Since the device tree and the code that trims it are bound into the kernel binary, these 'marker' properties never escape into the wild, and are purely an implementation detail of the kernel early boot process. This is done for backwards compatibility with existing boards (identified by a board type enumeration value by their bootloaders). New boards will always pass a device tree from the bootloader, the built-in trees are ignored in this case.

2012-07-23of/lib: Allow scripts/dtc/libfdt to be used from kernel codeDavid Daney
libfdt is part of the device tree support in scripts/dtc/libfdt. For some platforms that use the Device Tree, we want to be able to edit the flattened device tree form. We don't want to burden kernel builds that do not require it, so we gate compilation of libfdt files with CONFIG_LIBFDT. So if it is needed, you need to do this in your Kconfig: select LIBFDT And in the Makefile of the code using libfdt something like: ccflags-y := -I$(src)/../../../scripts/dtc/libfdt Signed-off-by: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Cc: devicetree-discuss@lists.ozlabs.org Cc: Grant Likely <grant.likely@secretlab.ca> Cc: linux-kernel@vger.kernel.org Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2012-07-23pwm: fix used-uninitialized warning in pwm_get()Thierry Reding
Some versions of GCC don't seem no notice that the initialization of the index variable is tied to that of the chip variable and falsely report it as potentially being used uninitialized. However, to save anybody else from tripping over this, we now initialize the index variable unconditionally.

2012-07-23pwm: Conflict with legacy PWM APIThierry Reding
In order to avoid duplicate symbols with legacy PWM API implementations, the new PWM framework needs to conflict with any of the existing legacy implementations. This is done in two ways: for implementations provided by drivers, a conflict is added to the driver to ensure it will have to be ported to the PWM subsystem before it can coexist with other PWM providers. For architecture-specific code, the conflict is added to the PWM symbol to avoid confusion when a previously picked platform or machine can no longer be selected because of the PWM subsystem being included.
