Recent drivers/mfd/twl4030* renames to twl broke compile for
various boards as the series was missing a patch to change
the board-*.c files.

This patch renames include twl4030.h to include twl.h
and also renames twl4030_i2c_ routines.

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030

OMAP3xxx and OMAP4430 UART IP blocks have a restriction wrt RX FIFO.
Empty RX fifo read causes an abort.

OMAP3xxx:
	UART IP revision >= 0x52 have this issue
	MVR register format is:
	Bits  Field Name  Description  				Type  Reset
	31:8   RESERVED 					RO  	0x0

	3:0    MINOR  	Minor revision number of the module.  	RO  	0x--

OMAP4xxx:
	All revisions have this issue
	Revision id check is not used as the format of MVR resigster has changed
	For omap4 MVR register reads as: 0x50410602 => Revision id = 0x0602
	Format of MVR register on omap4 is: (Courtesy: Cousson, Benoit)

CM-T35 can be assembled with different set of peripherals thus making
certain interfaces available to user as GPIOs or dedicated pins. Because
of it CM-T35 bootloader sets up mux configuration only for pins
necessary to boot the system and the rest of the mux configuration is
done by the kernel. Besides, having mux configuration in the kernel
allows to minimize dependancy on bootloader.

Pandora board file updates:
- change keycodes of game buttons
  it was decided not to use ABXY layout by the developers.
- drop i2c bus 3 speed to 100kHz
  this is needed for battery monitoring chip to work reliably.
- drop pandora_lcd platform_device
  the older DSS driver was never functional on l-o or mainline
  kernels due to missing panel driver, so remove unneeded
  pandora_lcd platform_device. This also removes last OMAP_TAG

Note that this data is __initdata, and gets optimized

is not set.

the SDMMC registers instead of 34xx naming with just

Initially only for 34xx. This code allows us to:

- Make the code more generic as the omap internal signal
  names can stay the same across omap generations for some
  devices

- Map mux registers to GPIO registers that is needed for
  dynamic muxing of pins during off-idle

- Override bootloader mux values via kernel cmdline using
  omap_mux=some.signa1=0x1234,some.signal2=0x1234

- View and set the mux registers via debugfs if
  CONFIG_DEBUG_FS is enabled

WARN if a clock/hwmod is missing a clockdomain association since
resulting hwmod will not be able to correctly enable/disable clocks.
Signed-off-by: NKevin Hilman <khilman@deeprootsystems.com>
Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Earlier, the hwmod code had considered the OCP_SYSCONFIG.CLOCKACTIVITY
bits to be incremental power saving bits, controlling internal IP
block clock gates.  This was a misapprehension.  The CLOCKACTIVITY
bits are used to indicate, in advance, which clocks will be cut when
the module acknowledges an idle request.  This enables the IP block to
take whatever action is necessary to complete any in-progress work
before asserting its IdleAck.

In the current Linux-OMAP code, this implies that the clock framework
should be changing module CLOCKACTIVITY bits as module clocks are enabled
and disabled.  We don't do that yet, but in the future, we should.
This must wait until the clock tree is annotated with omap_hwmod pointers
(or vice-versa).  In the meantime, drop most of the hwmod code that
controls CLOCKACTIVITY bits to avoid confusion.

This patch has benefited from many illuminating discussions with (in
alphabetical order) Benoît Cousson <b-cousson@ti.com>, Rajendra Nayak
<rnayak@ti.com>, and Sebastien Sabatier <s-sabatier1@ti.com>.

Replace the existing u8 array of module MPU IRQ lines with a struct
that includes a name - similar to the existing struct
omap_hwmod_dma_info.  Device drivers can then use
platform_get_resource_byname() to retrieve specific IRQs without nasty
dependencies on array ordering.
