[PATCHv4 0/9] *** ARM: Update arch-vt8500 to Devicetree ***

[Tony Prisk]

This patchset updates arch-vt8500 to devicetree and removes all the old-style
code. Support for WM8650 has also been added.

Example dts/dtsi files are given for the three currently supported models.

Major changes:

GPIO code has been converted to a platform_device and rewritten as WM8505
support was broken. Add support for WM8650 gpio controller.

UHCI support was missing. Added this as a generic non-pci uhci controller as
it doesn't require anything special. Should be usable by any system that doesn't
have special requirements to get the UHCI controller working.

Framebuffer code patched to support WM8650. The bindings for this are of concern
but there doesn't seem to be a formalized binding yet. This patch is based off
Sascha Hauer's current patch on the dri-devel mailing list and should be easily
patched out when its finalized.

Patchset based on Arnd's arm-soc/for-next branch.


Could I get this reviewed, hopefully for inclusion into v3.7.

Regards
Tony Prisk

Changes
v2:
Cleanup style/formatting errors
Removed erroneous commit message about GPIO not being converted to devicetree
Corrected arch-vt8500/irq.c header to correct filename
Changed GPIO driver to use module_platform_driver()
Renamed vt8500_gpio_bank_regs -> vt8500_gpio_bank_regoffsets
Changed vt8500_gpio_bank_regoffset fields to unsigned int
Changed bit-setting code to use BIT() macro
Removed of_find_compatible() and use pdev->dev.of_node in _probe()
Removed regoff field and related code - leftover from old design
Added kerneldoc regarding struct vt8500_gpio_bank_regoffsets fields
Update MODULE_LICENSE on all platform devices to "GPL v2" to match their headers
Renamed dts board files to clarify product names

v3:
Corrected serial driver issue after porting to device tree. pdev->id no longer
valid.
Corrected irq.c to properly initialize slaved interrupt controller.
Updated framebuffer drivers to use phandles for display node.
Corrected dts definitions for updated framebuffer driver.

EHCI/UHCI patch (Patch 4/9) already in -next via usb-next tree.

Included common clock frame support.
Added initialization code to arch/arm/mach-vt8500/vt8500.c for clocks.
Updated wm8650.dtsi to include basic clocks.

v4:
Added missing GPL header to clk-vt8500.c
Corrected unsigned variables in gpio-vt8500.c
Changed gpio-vt8500.c to use readl/writel _relaxed variants.
Update serial driver to get clock source from device tree.
Update dtsi files for uart clock sources.
Renamed vt8500_gpio.txt to vt8500-gpio.txt
Describe gpio flags property - currently no flags are defined, but will need
to be when gpio interrupts are supported. Kept for future compatibility.

Stephen W: I've taken a look on dri-devel mailing list and -next but haven't
seen a new binding document for Sascha's of_videomode_helper yet. I've left the
code as is for now - hopefully the OF helper will be formalized in this cycle.
I took a look at the GPIO flags - this was added on Arnd's recommendation as it
will be needed later once the GPIO controller is also an interrupt-controller.
I've add documentation that it should be =0 for now.
