This adds modifications to the core of the Glamo driver to expose functionality
to support DRM and KMS.

This adds the Glamo DRM and KMS driver, but not the modifications needed
elsewhere to support it.

As those constans are alread bitfields it's wrong
Those constants are already bitfields.

Since it is not use and probably never will be it's safe to remove it.

Currently the pcf50633-regulator driver data is set to the pcf50633 core
structure, but the pcf50633-regulator remove handler assumes that it is set to
the regulator device. This patch fixes the issue by accessing the pcf506533
core structure through its parent device and setting the driver data to the
regulator device.

Platform devices allocated with platform_device_alloc should use
platform_device_add_data to set the platform data, because kfree will be called
on the platform_data when the device is released.

Currently the child devices were not freed if the irq could not be requested.
This patch restructures the function, that in case of an error all previously
allocated resources are freed.

Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.

Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.
I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

The TWL4030 IRQ handler has a bug which leads to spinlock lock-up. It is
calling the 'unmask' function in a process context. :The mask/unmask/ack
functions are only designed to be called from the IRQ handler code,
or the proper API interfaces found in linux/interrupt.h.
Also there is no need to have IRQ chaining mechanism. The right way to
handle this is to claim the parent interrupt as a standard interrupt
and arrange for handle_twl4030_pih to take care of the rest of the devices.
