The check for a valid mux name should be performed regardless of whether
DEBUG_FS is enabled or not. Otherwise without DEBUG_FS, we get:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] *pgd=00000000
Internal error: Oops: 5 [#1]
last sysfs file:
Modules linked in:
CPU: 0    Not tainted  (2.6.33-rc8 #10)
PC is at strcmp+0x18/0x40
LR is at omap_mux_init_signal+0x68/0x14c
...

This fixes the issue currently seen with boards not booting up
if DEBUG_FS is not enabled in defconfig.

Note that the earlier ifndef + ifdef now becomes simpler ifdef else:
If CONFIG_OMAP_MUX is selected, we use pin names. If it's not selected,
we only want the GPIO to mux register mapping.

EMMC can have two voltage supplies, Vcc and VccQ
which are implemented in the code as consumer
supplies vmmc and vmmc_aux.

If the regulator that supplies vmmc_aux is shared
with other consumers, then sending it to sleep
will disrupt those consumers.  However, the
TWL4030-family regulators may have OFF remapped
to SLEEP, in which case 'regulator_disable()'
will put the regulator to sleep only when all
consumers are disabled - which is the desired
behaviour.

This patch adds a platform data field to allow
that option.

It has been discovered that, when eMMC is powered off, current
will flow from OMAP eMMC data pull-ups to the eMMC voltage supply.
Configuring pads for OMAP off-mode does not help because eMMC is
powered off independently of OMAP off-mode.  Hence the pads are
now re-configured when eMMC is powered on or off.

This patch moves the setup code for GPIO's and Voltage
Regulators from the board file mmc-twl4030.c to the
driver omap_hsmmc.c.  PBIAS and other system control
configuration remains in the board file.

Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined.  That makes the
board initialisation now entirely independent of its original
twl4030 roots.

Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code.  It also
permits the MMC core to be compiled as a module, because the
board code no longer calls MMC core functions.

This patch adds support for flashes on 3430SDP boards. All three
NAND, NOR and OneNAND are supported. I have tested it on
3430SDP (ES2 and ES3.1).

This patch can be treated as an example to "how to utilize":
'gpmc-nand.c' and 'board-sdp-flash.c'.

Similar patches can be created for 2430sdp and 3630sdp or any other
similar board.

This patch adds 'board-sdp-flash.c', which could be utilized
by boards similar to 3430SDP. (For ex: 2430sdp, 36030sdp).

This file does initialization for all three flash devices present
in SDP boards (NOR, NAND, OneNAND), by finding there 'cs' number
dynamically using switch setting information (S8: 1-4).
This also expects partition information from core board files (for
ex: board-3430sdp.c). Which allows to choose different default
partitions for different boards.

A new structure is created for this purpose: 'flash_partitions'
in 'mach/board-sdp.h'. This has two members:
1. struct mtd_partition *parts
2. int nr_parts

A board file is expected to fill this structure and pass it to
'sdp-flsash-init'. Partition information should be passed in
structure array of 'flash_partitions'. Partition information should
be passed in below sequence in array:
NOR
OneNAND
NAND
